Disorders of the cerebral hemisphere are best characterized electrically by electroencephalography, somatosensory evoked potentials, polysomnography, and movement recordings. Lesions in the posterior fossa may benefit from the addition of cranial conduction studies and brain stem auditory evoked potentials. Although a clinical neurophysiologic assessment rarely provides evidence for a specific diagnosis, it can provide valuable information about the severity, progression, and prognosis of the disease. Literature review of the usefulness of nerve conduction studies and electromyography in the evaluation of patients with ulnar neuropathy at the elbow. Comparison of electrodiagnostic criteria for primary demyelination in chronic polyneuropathy. Acquired inflammatory demyelinating polyneuropathies: Clinical and electrodiagnostic features. Dispersion of the distal compound muscle action potential as a diagnostic criterion for chronic inflammatory demyelinating polyneuropathy. Electrodiagnostic criteria for acute and chronic inflammatory demyelinating polyradiculoneuropathy. Electrophysiological features of inherited demyelinating neuropathies: A reappraisal in the era of molecular diagnosis. Diagnostic yield of single fiber electromyography and other electrophysiological techniques in myasthenia gravis. The results to be expected from electrical testing in the diagnosis of myasthenia gravis. Apparent conduction block in patients with ulnar neuropathy at the elbow and proximal Martin-Gruber anastomosis. The hand neural communication between the ulnar and median nerves: Electrophysiological detection. The contribution of median to ulnar communication in diagnosis of mild carpal tunnel syndrome. Median innervated hypothenar muscle: Anomalous branch of median nerve in carpal tunnel syndrome. The accessory deep peroneal nerve: A common variation in innervation of extensor digitorum brevis. This page intentionally left blank Glossary of Electrophysiologic Terms A Wave: A compound muscle action potential that follows the M wave, evoked consistently from a muscle by submaximal electric stimuli and frequently abolished by supramaximal stimuli. Thought to be due to extra discharges in the nerve, ephapses, or axonal branching. Accommodation: In neuronal physiology, a rise in the threshold transmembrane depolarization required to initiate a spike, when depolarization is slow or a subthreshold depolarization is maintained. In the older literature, the observation that the final intensity of current applied in a slowly rising fashion to stimulate a nerve was greater than the intensity of a pulse of current required to stimulate the same nerve. The latter may largely be an artifact of the nerve sheath and bears little relation to true accommodation as measured intracellularly. Acoustic Myography: the recording and analysis of sounds produced by the contracting muscle. The muscle contraction may be produced by stimulation of the nerve supply to the muscle or by volitional activation of the muscle. An all-or-none phenomenon; whenever the stimulus is at or above threshold, the action potential generated has a constant size and configuration. The force of muscle contraction is determined by the number of motor units and their firing rate. Activation Procedure: A technique used to detect defects of neuromuscular transmission during repetitive nerve stimulation testing. Most commonly a sustained voluntary contraction is performed to elicit facilitation or postactivation depression. Characterized by a time course of progression to maximum deficit within 4 weeks of onset of symptoms.

Recommendations for dose, vaccine storage and handling (see Vaccine Handling and and immunization schedules should be followed for predictable, effective immunization critical to the success of immunization practices at both the individual and the societal levels. To overcome these limitations and to facilitate polysaccharide processing by antigen-presenting cells, vaccine antigens are chemically conjugated to a protein carrier with proven immunologic potential (eg, tetanus toxoid, nontoxic variant of diphtheria toxin, meningococcal outer membrane protein complex) to improve the immune response. Allergic reactions may occur if the recipient is sensitive to one or more of these additives. Standardized forms are available to assist clinicians in screening for allergies and other potential contraindications to immunization ( From the Latin word for "to help," adjuvants are materials that are added to a vaccine to improve the immune response to the antigen. Aluminum salts, the most commonly used adjuvants, have been used in vaccines for more than 80 years and often are used in vaccines containing inactivated microorganisms or toxoids (eg, hepatitis B vaccine and diphtheria and tetanus toxoids). Despite their well-known clinical effect, their mechanism of action of stimulating an immune response via cytokine release was demonstrated only recently. Preservatives are added to multidose vials to prevent the growth of bac- teria or fungi that may be introduced into the vaccine during its use. In some cases, preservatives are used during the vaccine manufacturing process to inhibit microbial growth, Thimerosal has been the most commonly used preservative in vaccines. In use since growth of microorganisms that might inadvertently contaminate the vial with repeated penetrations to withdraw a dose. However, in shifting to single-dose formulations, all routinely recommended vaccines for infants and children in the United States are available only as preservative-free (eg, thimerosal-free) formulations or contain only trace dose vials, which contain thimerosal for its antimicrobial, preservative properties. This multidose preparation is produced to meet the needs of practitioners who often prefer tered in the early fall, between the time when vaccines become available and the onset thimerosal-free formulation, trace thimerosal-containing formulation, and thimerosal preservative-containing formulation. Thimerosal has been studied extensively and is associated with only rare, mild allergic reactions or other adverse events. Independent safety reviews by the Institute of Medicine regarding thimerosal-containing vaccines as well as vaccines and autism are available ( A recent review of vaccine preservatives by the World Health Organization highlighted that alternative preservatives, such as 2-phenoxyethanol, have variable antimicrobial effectiveness in some formulations. In addition, as for many ingredients, 2-phenoxyethanol has different compatibilities with genicity ( The effort to remove thimerosal (ethyl mercury) from vaccines was driven in large part by initial concerns about toxicity of methyl mercury, a mercurynot supported a link between thimerosal exposure and neurodevelopmental disorders, including autism. It is very clear that the use of thimerosal in vaccines does not put vaccine recipients at increased risk of neurodevelopmental problems. Overwhelmingly, the evidence collected over the past 15 years has failed to yield any evidence of harm from the United States, having the option for including thimerosal could be critical for dealing with emergencies and the need to increase vaccine supply and delivery rapidly, such as However, thimerosal as a preservative remains an important component of many vaccines used in resource-limited countries, particularly because of extensive use of multidose disposal. Multiple re-entries into multidose vials, however, increase the risk of microbial contamination, which is the impetus for thimerosal use in multidose vials in resource-limited settings. Stabilizers are added to vaccines to ensure that their potency is not affected by adverse conditions during the manufacturing process (eg, freeze drying) or during transport and storage (eg, mild temperature excursion). Stabilizers commonly added to vaccines for this purpose include sugars (sucrose or lactose), amino acids (eg, glycine), or proteins (eg, gelatin). Vaccine Handling and Storage For vaccines to be optimally effective, they must be stored properly from the time of manufacturing until they are administered. Immunization providers are responsible for proper storage and handling from the time the vaccine arrives at their facility until the vaccine is given. All staff should be knowledgeable about the importance of proper storage and handling of vaccines. It should detail both routine management of vaccines and emergency measures for vaccine retrieval and storage. It is imperative that great care be taken to avoid exposing "refrigerated vaccines" to freezing temperatures, even for brief periods. Such exposure can compromise the integrity of refrigerated vaccine even without generating ice crystals or other changes in physical appearance of the vaccine.

In the older age group, progression to chronic (postherpetic) neuralgia is not uncommon. Complications Acute glaucoma and corneal ulceration due to vesicles have been reported. Summary of Essential Features and Diagnostic Criteria Herpetic vesicular eruption in distribution of first division of trigeminal nerve. Signs and Laboratory Findings Clusters of small cutaneous vesicles, almost invariably in the distribution of the ophthalmic distribution of the trigeminal. Postherpetic Neuralgia (Trigeminal) (11-5) Definition Chronic pain with skin changes in the distribution of one or more roots of the Vth cranial nerve subsequent to acute herpes zoster. Signs and Laboratory Findings Cutaneous scarring, loss of normal pigmentation in area of earlier herpetic eruption. Hypoesthesia to touch, hypoalgesia, hyperesthesia to touch, and hyperpathia may occur. Pain Quality: sharp, lancinating, shocklike pains felt deeply in external auditory canal. Summary of Essential Features and Diagnostic Criteria Onset of lancinating pain in external meatus several days to a week or so after herpetic eruption on concha. X2 Neuralgia of the Nervus Intermedius (11-7) Note: this condition is admittedly very rare and is presented as a tentative category about which there is still some controversy. Definition Sudden, unilateral, severe, brief, stabbing, recurrent pain in the distribution of the nervus intermedius. Page 63 Periodicity is characteristic, with episodes occurring for weeks or months, and then months or years without any pain. Or from surgical procedures: microsurgical decompression of the nervus intermedius or section of the nerve. Pathology Most patients have impingement on the nervus intermedius at its root entry zone. Essential Features Unilateral, sudden, transient, intense paroxysms of electric shock-like pain in the ear or posterior pharynx. Usual Duration: episodes last for weeks to a month or two and subside spontaneously. Signs and Laboratory Findings the important and only sign is the presence of a trigger point, usually on fauces or tonsil; sometimes it may be absent. Page 64 Neuralgia of the Superior Laryngeal Nerve (Vagus Nerve Neuralgia) (11-9) Definition Paroxysms of unilateral lancinating pain radiating from the side of the thyroid cartilage or pyriform sinus to the angle of the jaw and occasionally to the ear. Site Unilateral, possibly more on the left in the neck from the side of the thyroid cartilage or pyriform sinus to the angle of the jaw and occasionally to the ear. Combined ratio of vagoglossopharyngeal neuralgia to trigeminal neuralgia is about 1:80. Pain Quality: usually severe, lancinating pain often precipitated by talking, swallowing, coughing, yawning, or stimulation of the nerve at its point of entrance into the larynx. Essential Features Sudden attacks of unilateral lancinating pain in the area of the thyroid cartilage radiating to the angle of the jaw and occasionally to the ear. X8e Occipital Neuralgia (11-10) Definition Pain, usually deep and aching, in the distribution of the second cervical dorsal root. Main Features Prevalence: quite common; no epidemiological data; most often follows acceleration-deceleration injuries. Pain Quality: deep, aching, pressure pain in suboccipital area, sometimes stabbing also. Page 65 Summary of Essential Features and Diagnostic Criteria Intermittent episodes of deep, aching, and sometimes stabbing pain in suboccipital area on one side. Such changes are particularly present in the so-called third segment of the ophthalmic vein and in the cavernous sinus. Milder forms apparently exist; during recurrences in particular, the pattern may be less characteristic. Pathology Fibrous tissue formation in cavernous sinus area, involving various structures, vein wall, etc. Attacks may be triggered by various types of minor stimuli within the innervation zone of the Vth cranial nerve but also by neck movements. Precipitating Factors Attacks may be triggered by minor stimuli within the distribution of the Vth cranial nerve, but also partly by neck movements. Associated Symptoms and Signs Conjunctival injection, lacrimation, nasal stuffiness, and to a lesser extent, rhinorrhea and forehead sweating (which is apparently always subclinical) occur on the pain side.

With every visit, Alek continued to experience more motion, increased strength and less pain. Assuming that the hinge on a cabinet door has three screws, and one of the screws begins to loosen, what happens to the other screws? There is more pressure transmitted to the other screws, more pressure than they are designed to handle. However, it was not designed to handle this extra pressure, and thus continues the breakdown of that next hinge as well. To fix the problem of the loose hinge on a cabinet door, what would you attempt first? We bet your first choice would be to use a screwdriver to tighten the screws on the hinge! When the hinge is loose and allowing the door to wobble on a cabinet door, it begins to bang against the other door and eventually the wood of the door will warp and chip off. This causes pressure and destructive changes in the subchondral bone and the cartilage. Other athletes experience repeated strain on the back due to posture, such as back packing and hiking. Unfortunately, many patients are left with even more pain because the surgery that was supposed to strengthen the weak area actually ended up weakening the area to the point that the non-surgerized back was actually stronger. Cumulative injury (without repair) over years of sports or improper movement can result in small tears in these ligaments. Instability and ligament laxity with resultant instability cause chronic low back pain. But you cannot discount the growing frequency of osteoarthritis of the thumb, particularly at the base of the thumb. Hardening of the bones or joints (sclerosis) is typically the earliest x-ray sign of joint instability and osteoarthritis. The bone is hardening because of greater pressure on it due to ligament injury causing joint hypermobility or instability. This particular patient was recommended a multi-level fusion, but she chose Prolotherapy instead. When none of these treatments cure the problem, patients are left with the option of surgical repair. Like arthritis anywhere else in the body, the pain comes from joint instability as a result of ligament laxity. Traditional medicine will report that thumb pain is due to cartilage degeneration. Smart phone syndrome is a major contributing factor of overuse, as mentioned in Chapter 11. Tighten those with Prolotherapy and the patient is well on his/her way to pain-free living. Many of the patients who participated in our Prolotherapy results studies had chronic pain due to osteoarthritis. A patient with plenty of cartilage can still have pain, and a patient with almost no cartilage can feel pain-free. That said, it is still great to see that Prolotherapy has the power to maintain and regenerate cartilage on x-ray in every joint of the body! The widening of the medial joint space width indicates that cartilage regeneration has taken place. Figure 13-12: Standard weight-bearing bilateral knee x-rays before and after Prolotherapy. In these instances, this inflammation is counterproductive because the body is reacting against its own immune system. Correcting the underlying cause of why the body is attacking itself is key to reversing these conditions. We occasionally see patients where the bone has deformed due to unresolved joint instability with continued joint usage. In a ball and socket joint, such as the hip, the head of the femur bone should be round.

Then visualise a flaming torch, and invoke the power of the Holy Ghost, whose symbol it is. Then sear the stump with the consecrated fire of the torch until it shrivels up and falls off from its point of attachment to your body. After such a severing one must, of course, take the ordinary human precautions to prevent the link being re-formed. Refuse to meet the person responsible for its formulation, or to either read or answer letters from him. In fact, cut off physical communications as thoroughly and resolutely as one has cut off astral ones for a period of some months at least. If he can visualise its other point of attachment in the dominator, so much the better. He must not use either sword or torch for this process, but break it with his own flesh, as it were. Having thus severed it from his friend, he should then go for it with sword and torch with all his strength as it tries to enwrap him, as it assuredly will do, for it resembles nothing so much as the tentacle of an octopus. He should go for it hammer and tongs, making up in zeal what he lacks in knowledge, until it has had enough, and begins to curl up and withdraw. I was asked if I could help a woman who had been a lifelong invalid, but whose case the many doctors she had consulted were neither able to diagnose satisfactorily, nor to help. They all agreed that there was nothing organic the 92 of 103 matter with her, and after trying in vain to get her better, they generally united in saying that it was pure hysteria. She suffered from a chronic condition of exhaustion, indigestion, attacks of vomiting, blinding headache and palpitation of the heart. In her present life, she retained the powers her training had given her, but not the memory of its technique. Whenever, therefore, she was emotionally disturbed, her subconscious mentation overflowed into the automatic mind and threw certain of the functional systems of the body out of gear. It may be recalled that the famous scientist, Sir Francis Galton, the founder of the science of eugenics, experimented with mental control of respiration, and having obtained it, found that the automatic function had fallen into abeyance, and he had to spend three anxious days breathing by will power and voluntary attention until the automatic function was re-established. This is one of the reasons why the great Mystery Schools have no need to make themselves known by advertising, they know their own, and pick them up on the astral plane. I perceived that from her solar plexus as she lay asleep there stretched a black, elastic, stringy-looking substance that resembled nothing so much as a stick of Spanish liquorice that has been well chewed by a small boy. Upon trying to see its further end I had a brief and far-off vision of a monastery with a Chinese type of roof perched on a crag among vast mountains. It immediately transferred itself to my solar plexus, and for a moment I felt a surge of tempting thoughts urging me to get this woman under my thumb and exploit her to her full financial capacity. I told her that in my opinion she ought to have nothing whatever to do with occult studies lest she re-form the magnetic link with her old Order, and also taught her how to prevent her subconscious mind from giving disruptive suggestions to her bodily systems of functional control. Innumerable instances were reported by the men returning from the trenches during the War. We learn here of the Good Angel and the Evil Angel of the soul of man who stand behind his right and left shoulder, the one tempting him, and the other inspiring him. But the Freudians fail to realise that there is also a Bright Angel who stands behind the right shoulder of every man. This is the mystic superconsciousness or, in other words, the Higher Self, the Holy Guardian Angel whom Abramelin sought with such ardour and effort. They take place only in times of dire stress and go as swiftly as they came, leaving no trace except upon the soul. I maintain that even as the Lower Self can rise up in moments of temptation, so can the Higher Self descend in moments of spiritual crisis. All emotional turmoil ceases, and one is like a ship hove-to, securely riding out the storm. Yet there can be no breach of natural law; there fore such a miracle must simply be an example of the working of a law with which we are as yet unfamiliar, just as an eclipse appears to the savage as a miracle, but to the astronomer as a natural phenomenon which he can forecast with accuracy. May it not be that our minds are also geared, and that it is a changing of gears which induces psychism? When we "change gear," consciousness is shifted from a denser to a subtler plane and we begin to move among remoter and remoter causes of which the happenings upon the physical plane are the end-results; we manipulate these causes and the results are immediately effected. There are many souls who have this mystical spiritual consciousness although they have no occult knowledge. The question of mystical consciousness is, however, outside the scope of our present enquiry, which is concerned with psychic methods and the traditional technique of the occultist.

Significant reductions in pain at rest, during normal activity, and during exercise were reported. The posterior cervical sympathetic syndrome became known as Barr?ieou syndrome and cervicocranial syndrome. A reasonable question to ask is: How can one disorder cause all of these problems? In cervicocranial syndrome, the posterior cervical sympathetic system is underactive because the vertebrae in the neck are pinching the sympathetic nerves. Symptoms can include dysphagia, tongue Another symptom of numbness, blurred vision, tinnitus, vertigo, dizziness, neck pain, and cervicocranial syndrome migraine headaches. A decrease in sympathetic output to the inner ear will cause an accumulation of fluid in the inner ear. When fluid accumulates in the inner ear, as is often the case with an upper respiratory infection, the ear feels full and the body feels off balance. People using decongestants for years for "chronic allergies" and "chronic sinus infections" are often immediately helped by Prolotherapy injections into the head and neck region. Weakness of the neck ligaments commonly occurs because most people spend a good portion of their days looking down at phones and hunched over while working. Creep, which is a term signifying the slow stretching of ligaments, most commonly occurs by a forward head posture from computer work or looking at a smart phone. However, about "15-20% developed the so-called late whiplash injury syndrome, with many complaints of the cervico-encephalic syndrome, including headache, vertigo, instability, nausea, tinnitus, hearing loss, etc. Migraine sufferers know that pain on one side in the base of the neck may be the Figure 5-7: Prolotherapy to the cervical facet joints. By stabilizing the vertebral motion, Prolotherapy resolves the important clue that the impingement of the cervical sympathetic ganglion and the etiology of the headache resultant symptoms. They found that Prolotherapy was effective in completely relieving the headaches in 79% of patients. Whether as a computer operator typing at the terminal, a cook cutting up carrots, or a surgeon performing an operation, the head-forward neck-bent posture stretches the cervical ligaments and the posterior neck muscles, including the levator scapulae and trapezeii. Prolotherapy, however, will not overcome poor posture or poor dietary and lifestyle habits. Facet joints are the small joints that connect one vertebra to the vertebrae below and above it and have been shown to be a significant generator Figure 5-11: the process of facet (Z) joint and disc degeneration and the interrelation between the two. The patient may feel better right away, but these effects often do not last long-term. Before this happens, it is much easier for a person to regenerate the ligament tissue that allow the proper movement of facet joints, and stability of the spine through Prolotherapy. These include neck pain, headaches, dizziness, vertigo, fatigue, numbness and tingling of the face and tongue, tinnitus, nausea/vomiting, balance difficulties, drop attacks, difficulty swallowing, and migraines. In our experience, ?Migraine or subProlotherapy can offer a tremendous occipital headaches amount of hope and relief of symptoms in these cases. Many of these symptoms overlap with those of atlanto-axial instability, cervicocranial syndrome, and whiplash-associated disorder. If you fall and hit your head on the ground, it is easy to understand that the fall would put a large force on the skull. In addition to that, however, that same force can also be transmitted to the ligaments of the upper cervical spine. Overlap in symptoms exists due to underlying cervical instability found in each of the conditions. Further explanation could be that post-concussion syndrome, which was once thought to be due to residual brain trauma, could be the result of upper cervical instability that develops during the injury. Symptoms of post-concussion syndrome occur long after imaging of the brain appears normal, suggesting that there is another cause for the headaches, dizziness, etc. It is likely that this other cause is ligament laxity in the upper cervical spine. Anyone that has ever been rear-ended knows that a lot of force is placed on your neck when your head moves forward and then backward after the car has been hit. Common symptoms of whiplash-associated disorder include neck pain, headache, dizziness, vertigo, crepitation in the neck, fatigue, irritability, tinnitus, nausea/vomiting, cognitive impairment, anxiety, lightheadedness, and memory problems. Vertebrobasilar insufficiency, also known as vertebrobasilar artery insufficiency, occurs when blood flow is disrupted, such as from blood clots or ruptures of the artery. We most commonly see that this condition is due to underlying upper cervical instability.

Indeed, many have come to rely on observation, on advice from colleagues, and on building experience empirically through their own treatment successes and failures. The disparity of theoretical and practical availability of information is due to several factors, including unequal distribution of Internet access, and also a failure of international development policies and initiatives, which have tended to focus on innovative approaches for higher-level health professionals and researchers while ignoring, relatively speaking, other approaches that remain essential for the vast majority of primary and district health workers. The information poverty of health workers in low-resource settings is exacerbating what is clearly a public health emergency. Primary and district health workers should be at the center of efforts to address this crisis. The availability of health information may ix provide confidence in clinical decision-making, improving practical skills and attitudes to care. Thus, any physician, nurse, or other clinical worker needs to have basic knowledge about the pathophysiology of pain and should be able to use at least simple first-line treatments. Unlike "special pain management," which should be reserved for specialist physicians with specific postgraduate training in complex pain syndromes, knowledge of "general pain management" is a must for all other health care workers to prepare them for the majority of patients in pain with common pain syndromes. The main focus of the Guide is to address the following four pain syndromes: acute post-traumatic postoperative pain, cancer pain, neuropathic pain, and chronic noncancer pain. The editors understand the barriers and future needs regarding good pain management. These barriers include lack of pain education and a lack of emphasis on pain management and pain research. In addition, when pain management does feature in government health priorities, there are fears of opioid addiction, the high cost of certain drugs, and in some cases, poor patient compliance. In developing countries, the available resources for health care understandably focus on the prevention and treatment of "killer" diseases. Yet most such disease conditions are accompanied by unrelieved pain, which is why pain control matters in the developing world, according to Prof. However, it is a sad reality that the medicines that are essential for relieving pain often are not available or accessible. There are numerous reports, some of them published in major medical and science journals, about the deficits of adequate pain management, predominantly in developing countries in all regions of the world. For the pain specialist in developed countries, plenty of detailed information is available, but for the non-pain specialist and other health care providers, including nurses and clinical staff in many other regions of the world, who have to deal with patients in pain, there is a lack of a basic guide or manual on pain mechanisms, management, and treatment rationales. This is of particular concern in areas of the world where, outside the main urban areas, there is no access to information about pain etiology or management and no access to a pain specialist. The educational grant program, the "Initiative for Improving Pain Education," addresses the need for improved education about pain and its treatment in developing countries by providing educational support grants. These grants are intended to improve the scope and availability of essential education for pain clinicians of all disciplines, taking into account specific local needs. The result is this Guide, which is intended to provide Introduction concise and up-to-date-information in a novel curriculum structure for the medical practitioner in countries belonging to the developing world. It will also serve medical faculties by suggesting core curriculum topics on pain physiology and management. It is believed that the project will encourage medical colleges to integrate these educational objectives into their local student and nursing curriculums. It will provide the non-pain specialist with basic relevant information-in a form that is easily understood-about the physiology of pain and the different management and treatment approaches for different types and syndromes of pain. Any practitioner who deals with pain problems must be aware of the entire range of pathophysiological and psychopathological problems that are commonly encountered in pain patients, and must therefore have access to a reasonable range of medical, physical, and psychological therapies to avoid imposing on the patients and society any additional financial and personal costs. Therefore, this book will encourage the management of patients with acute and chronic pain, since it is well understood from the literature that even basic education has a considerable impact on the quality of analgesic therapy for the patient. The editors appreciate the enthusiasm and efforts put in by the volunteer authors of this Guide, without whom this book would not have been possible. Many have experience in the problems faced by health care providers in the developing world. They have tried to project their thoughts into particular situations and settings: "Can I cope with what is expected of me, working as a doctor or nurse or health care provider in a developing country and facing a wide range of pain problems?

The stimulus is applied on one side initially and then on two sides simultaneously in corresponding parts of the body. The latter tests for sensory extinction where the patient may fail to register stimulation of one side (the left usually) in lesions of the nondominant hemisphere. If any abnormalities are detected, attempts should then follow to accurately map the area of the deficit and establish the anatomical site of the lesion or the structure involved. Pain and temperature tests yield information on the same systems, and therefore it may not be necessary to test for both in the routine patient without neuropathic pain. However, a positive increase or pathological increase in sensation (like dysesthesia) that may have partly been picked up during history taking will need to be elucidated further. Regions of hyperesthesia and allodynia need to be mapped out accurately, noting that skin hypersensitivity to various stimuli (touch, cold, and warmth) may be different and therefore should be tested separately. Light touch, joint position, and vibration should be tested even though they are physiologically related in that they are all fast sensations, because they may be affected differentially in certain clinical situations. Higher sensory functions such as two point discrimination, graphesthesia (recognition of numbers or letters drawn on the skin), and stereognosis (ability to recognize familiar objects placed in the hand) are not normally part of a routine neurological examination but can be performed where a cerebral lesion is suspected. The deep tendon reflexes are normally tested after the examination of the sensory systems. The jaw jerk, the supinator, the biceps, the triceps jerks in the upper limbs and the knee and the ankle jerks in the lower limbs are routinely tested. Others like finger flexion and adductor reflexes in the upper and lower limbs respectively are not routine. Their responses are usually graded in a simple How do I examine the sensory system? There are two types of sensations physiologically: 84 five point system from 0 to 4: 0 = absent, 1 = decreased, 2 = normal, 3 = increased, and 4 = increased with clonus. Of particular interest is the symmetry of responses and the least force necessary to elicit the responses which may be a more sensitive measure than the grading system above. Comparison between the upper limbs and the lower limbs may yield some information regarding spinal cord lesions. Before recording a reflex as absent, a re-enforcing technique (like contracting muscles in other limbs or clenching the jaws) should be tried. The hall mark of upper motor neuron deficit remains the increased deep tendon reflexes, disappearance of superficial reflexes and appearance of pathological reflexes. The so-called primitive or frontal lobe release reflexes (grasp, pouting, rooting, etc. The cerebellum coordinates muscle contractions and movements in all voluntary muscles, and cerebellar dysfunction results in symptoms of ataxia that is truncal if the flocculonodular lobe is affected or limb ataxia if the hemispheres are at fault. Truncal ataxia is associated with disturbed gait that is typically broad based and reeling and does not get worse when eyes are closed. This can be observed when the patient walks into the examination room or when he/she is requested to walk naturally in the room. Tandem walking (10 steps), heel walking, and one leg stances (holding form more than 10 seconds) can also be tested. The neurophysiological process of movement coordination is a complex one requiring an intact ascending sensory system, basal ganglia, the pyramidal system and the vestibular apparatus. Lesions in one of these structures may impair one or other aspect of coordination. Fortunately such lesions will usually be accompanied by other neurological manifestations that help discriminate lesions. Limb coordination to assess cerebellar function may be tested using a variety of tests: the finger-nose test, rapid finger tapping, and rapid alternating hand movements in the upper limbs, and the heel to shin test and foot tapping in the lower limbs. The patient is a 46-year-old male who was pinned between a loading dock and a truck bumper several hours ago. His left lower extremity is in a temporary cardboard splint, and after a primary evaluation, he seems not to have other significant injuries. Your initial examination of the left lower extremity shows a swollen calf with a mild angular deformity and bruised but closed skin. Examination of the knee shows no effusion, but range of motion and ligament testing are not possible because of calf pain. He states he can feel you touch the toes and foot, but they have a tingling feeling; slightly different than the right.

The force of contraction associated with the interference pattern should be specified. The following are measured in the time domain: (1) the number of turns 852 Glossary of Electrophysiologic Terms per second and (2) the amplitude, defined as the mean amplitude between peaks. International 10?0 System: A system of electrode placement on the scalp in which electrodes are placed either 10% or 20% of the total distance on a line on the skull between the nasion and inion in the sagittal plane and between the right and left preauricular points in the coronal plane. Interpeak Interval: Difference between the peak latencies of two components of a waveform. Intraoperative Monitoring: the use of electrophysiological stimulating and recording techniques in an operating room setting. The term is usually applied to techniques which are used to detect injury to nervous tissue during surgery or to guide the surgical procedure. Involuntary Activity: Motor unit action potentials that are not under volitional control. The condition under which they occur should be described, for example, spontaneous or reflex potentials. Isoelectric Line: In electrophysiologic recording, the display of zero potential difference between the two input terminals of the recording apparatus. In conditions of disturbed neuromuscular transmission, including early reinnervation and myasthenic disorders, the variability can be sufficiently large to be easily detectable by eye. Quantitative methods for estimating this variability are not yet widely available. Jitter: the variability of consecutive discharges of the interpotential interval between two muscle fiber action potentials belonging to the same motor unit. Jolly Test: A technique named after Friedrich Jolly, who applied an electric current to excite a motor nerve repetitively while recording the force of muscle contraction. Kinematics: Technique for description of body movement without regard to the underlying forces. Late Component (of a Motor Unit Action Potential): See preferred term, satellite potential. Late Response: A general term used to describe an evoked potential in motor nerve conduction studies having a longer latency than the M wave. The onset latency is the interval between the onset of a stimulus and the onset of the evoked potential. The peak latency is the interval between the onset of a stimulus and a specified peak of the evoked potential. Latency of Activation: the time required for an electric stimulus to depolarize a nerve fiber (or bundle of fibers as in a nerve trunk) beyond threshold and to initiate an action potential in the fiber(s). An equivalent Glossary of Electrophysiologic Terms 853 term, now rarely used, is the "utilization time. Lipoatrophy: Pathologic loss of subcutaneous fat and connective tissues overlying muscle which mimics the clinical appearance of atrophy of the underlying muscle. Long-Latency Reflex: A reflex with many synapses (polysynaptic) or a long pathway (long-loop) so that the time to its occurrence is greater than the time of occurrence of short-latency reflexes. Long-Loop Reflex: A reflex thought to have a circuit that extends above the spinal segment of the sensory input and motor output. Should be differentiated from reflexes arising from stimulation and recording within a single segment or adjacent spinal segments (i. M Wave: A compound muscle action potential evoked from a muscle by an electric stimulus to its motor nerve. By convention, the M wave elicited by a supramaximal stimulus is used for motor nerve conduction studies. Ideally, the recording electrodes should be placed so that the initial deflection of the evoked potential from the baseline is negative. Normally, the configuration is biphasic and stable with repeated stimuli at slow rates (1? Hz). The following characteristics can be specified quantitatively: (1) maximal peakto-peak amplitude, (2) area contained under the waveform, and (3) number of phases. Malignant Fasciculation: Used to describe large, polyphasic fasciculation potentials firing at a slow rate. This pattern has been seen in progressive motor neuron disease, but the relationship is not exclusive. Membrane Instability: Tendency of a cell membrane to depolarize spontaneously in response to mechanical irritation or following voluntary activation.

All meats, eggs, animal fats and processed and denatured fats as well as fried foods should be avoided. The diet should also exclude refined carbohydrates, especially sugar, sugar products, alcohol, soft drinks, cakes, puddings, ice-cream, coffee and citrus fruits. Dinner: Vegetable oil, one or two lightly cooked vegetables, baked potato, brown rice or whole wheat chappati and a glass of buttermilk. They also induce concentrations of the gall-bladder, thereby improving the flow of bile. A warm water enema at body temperature will help eliminate faecal accumulations if the patient is constipated. Exercise is essential as physical inactivity can lead to lazy gall-bladder type indigestion which may ultimately result in the formation of stones. It is a troublesome condition which may lead to many complications including ulcers if not treated in time. The inflammatory lesions may be either acute erosive gastritis or chronic atrophic gastritis. Symptoms the main symptoms of gastritis are loss of appetite, nausea, vomiting, headache and dizziness. In more chronic cases, there is a feeling of fullness in the abdomen, especially after meals. Prolonged illness often results in the loss of weight, anaemia and occassional haemorrhage from the stomach. Causes the most frequent cause of gastritis is a dietetic indiscretion such as habitual overeating, eating of badly combined or improperly cooked foods, excessive intake of strong tea, coffee or alcoholic drinks, habitual use of large quantities of condiments, sauces, etc. Use of certain drugs, strong acids and caustic substances may also give rise to gastritis. Treatment the patient should undertake a fast in both acute and chronic cases of gastritis. By fasting, the intake of irritants is at once effectively stopped, the stomach is rested and the toxic condition, causing the inflammation, is allowed to subside. Elimination is increased by fasting and the excess of toxic matter accumulated in the system is thrown out. Lunch: Steamed vegetables, two or three slices of whole meal bread or whole wheat chappatis, according to the appetite and a glass of butter milk. The patient should avoid the use of alcohol, nicotine, spices, and condiments, flesh foods, chillies, sour things, pickles, strong tea and coffee. Eight to 10 glasses of water should be taken daily but water should not be taken with meals as it dilutes the digestive juices and delays digestion. Application of heat, through hot compressor or hot water bottle twice in the day either on an empty stomach or two hours after meals, should also prove beneficial. Far sighted persons are more prone to develop this disease than near sighted ones. There is gradual impairment of vision as glaucoma develops, and this may ultimately result in blindness if proper steps are not taken to deal with the disease in the early stages. But, in reality, the root cause of glaucoma is a highly toxic condition of the system due to dietetic errors, a faulty life style and the prolonged use of suppressive drugs for the treatment of other diseases. Glaucoma is also caused by prolonged stress and is usually a reaction of adrenal exhaustion. In the region of the eyes, the excess fluid causes the eye ball to harden losing its softness and resilience. Consequently, even after the operation, there is no guarantee whatsoever that the trouble will not recur, or that it will not affect the other eye. The natural treatment for glaucoma is same as that for any other condition associated with high toxicity and is directed towards preserving whatever sight remains. The patient should not take excessive fluids, whether it is juice, milk or water at any time. The breakfast may consist of oranges or grapes or any other juicy fruits in season and a handful of raw nuts or seeds. It has been found that the glaucoma patients are usually deficient in vitamins A, B,C, protein,calcium and other minerals. Nutrients such as calcium and B complex have proved beneficial in relieving the intraocular condition.
