This pathophysiological mechanism plays an important role in obesity, especially in morbidly obese patents seeking for bariatric surgery. Untl recently, obesity was believed to be protectve against osteoporotc fractures. Nevertheless, if we have a look at modifable osteoporosis risk factors we will see that the most signifcant risk factors are typical for obesity. Obese patents have vitamin D defciency, low physical actvity and sex steroid defciency. However, traumatology departments report a surprisingly high proporton of obese postmenopausal women atending the clinic with fractures. Subsequently, multple studies have demonstrated the importance of obesity in the epidemiology of fractures. Obese women are at increased risk of fracture in ankle, leg, humerus, and vertebral column and at lower risk of wrist, hip and pelvis fracture when compared to non-obese women . Furthermore, falls appear to play an important role in the pathogenesis of fractures in obese subjects. In their study both groups had a rather high rate of (10-50%), folic acid (40-45%), calcium and vitamin D (60-80%) defciencies despite regular vitamin supplementaton in all .

What is the acute response of systolic and diastolic blood pressure to symptoms jaundice buy rivastigimine without prescription aerobic exercise?

The constriction of vessels in the lung shunts blood to the areas of the lung that are better ventilated. Discuss the effect long-term endurance training has on the heart and on blood volume. Increases in plasma volume occur shortly after the initiation of intense endurance training. Higher plasma volumes cause an increase in venous return, left ventricular end-diastolic volume, and stroke volume. Hypertrophy of myocardial muscle also occurs with endurance training, but this is a slower process. To improve anaerobic capacity, several bouts of intense exercise should be performed for at most 1 minute in duration with 3 to 5 minutes of recovery between bouts. Which type of muscle fiber is activated during moderate-intensity, long-duration exercise, such as jogging? Which type of muscle fiber is activated during high-intensity, short-term exercise, such as sprinting? Explain why movements become less precise and refined as low-intensity exercise is continued for a prolonged period of time. Initially, low-intensity exercise uses motor units consisting of slow-twitch muscle fibers. These motor units have fewer muscle fibers than motor units with fast-twitchfibers, and this accounts for bettercontrol during low-intensity exercises compared with high-intensity exercises. If low-intensity exercise is prolonged to the point that glycogen is depleted, the fast-twitch motor units are recruited. These motor units have more muscle fibers and result in less control of movements. Type 1 fibers cannot be converted to type 2 fibers, but type 1 fibers can improve their ability to use anaerobic metabolism, and type 2 fibers can improve their ability to use aerobic metabolism. Type 2b fibers can be converted to type 2a fibers with endurance training or strength training. This is caused by an increase in capillary and mitochondria content and aerobic oxidative enzyme activity. The cross-sectional area of the muscle decreases, resulting in shorter diffusion distances for oxygen and carbon dioxide. Resistance training causes synthesis of proteins in thick and thin filaments, resulting in an increase in the cross-sectional area. The aerobic capacity of the muscle decreases, which hinders performance in endurance activities. It takes about 6 to 8 weeks for the addition of protein filaments, but conversion of type 2b to type 2a fibers begins after about 2 weeks. These hormones inhibit the release of luteinizing hormone and follicle-stimulating hormone, which results in decreased levels of estradiol. Studies have shown that physical and emotional stress, diet, and the presence of menstrual irregularity before training also contribute. There is some evidence to suggest this, but there is also evidence stating otherwise. Summarize some physiologic changes that occur during pregnancy that affect exercise. After the first trimester, the supine position results in relative obstruction of venous return by the enlarging uterus and a significant decrease in cardiac output. Stroke volume and cardiac output during steady-state exercise are increased significantly. Exercise during pregnancy induces a greater degree of hemoconcentration than does exercise in the nonpregnant state. For vigorous intensity physical activity, 20 minutes for 3 days per week is recommended. Such a program decreases weight, decreases fat mass, and maintains or increases fat-free mass. Exercise should be performed at least 3 days per week at an intensity and duration to expend 250 to 300 kilocalories per exercise session for a 75-kg person. This usually requires a duration of at least 30 to 45 minutes for a person in average physical condition. Type of exercise should include weight-bearing endurance activities such as tennis, stair climbing, and jogging intermittently during walking; jumping activities such as volleyball and basketball; and resistance exercises that involve all major muscle groups, such as weight lifting. How do exercise and training affect the endocrine system and the resting levels of hormones? Most hormone levels increase during submaximal, short-term exercise with the exception of insulin, which decreases, and thyroid hormones, which do not change. Discuss prolonged, moderate-intensity exercise training and blood glucose levels in individuals with type 1 and type 2 diabetes. Blood glucose levels do not seem to change with a prolonged exercise program in individuals with type 1 diabetes, but they decrease in individuals with type 2 diabetes. Exercise causes the cells of type 2 diabetic patients to be less resistant to insulin. Exercise may help to reduce body fat percentage, which results in an increase in the number of insulin receptors, an increase in their sensitivity, or both. This, along with the accompanying weight loss, decreases the cardiovascular risk factors of these individuals, which is the most significant benefit of performing exercise. Although exercise has not been shown to improve blood glucose levels in individuals with type 1 diabetes, it is still recommended for the same reasons that exercise is recommended for individuals without diabetes. Some studies have shown improvements in endurance, whereas others have found no change. How does the heart rate response to exercise differ between normal individuals and individuals who have had heart transplants? In normal individuals, heart rate increases rapidly with moderate exercise as a result of a decrease in parasympathetic nerve activity and an increase in sympathetic nerve activity. Any change in heart rate must be caused by changes in circulating levels of catecholamines, which takes more time than altering nerve activity. It takes longer for the heart rate to increase when exercise is initiated, and it takes longer for it to return to resting levels after exercise. How does resting heart rate differ between normal individuals and individuals who have had heart transplants? Resting heart rate is higherin individuals who have had a heart transplant becausethey no longer have the normal parasympathetic tone to slow the intrinsic rate of depolarization of the sinoatrial node. Why are individuals with thoracic-level spinal cord injuries at risk for fainting after exercising in the upright position with the upper extremities? There is no sympathetic innervation to the lower limb vasculature, and there may not be any innervation to the adrenal glands (depending on how high the injury is). Compared with a thermoneutral environment, exercising in the cold results in less lipid metabolism and free fatty acid use but greater lactate production and higher ventilation, oxygen consumption, respiratory heat loss, and peripheral heat loss. List possible causes for decreased maximal muscle strength and power with hypothermia. What are the two most common problems associated with exercising in hot environments? These problems cannot be avoided completely, but they can be limited by ingesting fluid while exercising. There appears to be a similar benefit between ingestion of pure water compared with carbohydrate and electrolyte drinks as far as controlling core temperature and cardiovascular changes. The principal physiologic responses of exercise in the heat include skin and muscle vasodilation, nonactive tissue vasoconstriction, maintenance of blood pressure, and sweating. Hematocrit levels increase after about 25 days of exposure to high altitude, which should increase performance. Some studies indicate that pulmonary function, cardiac output, muscle enzyme capacity, and lean body mass decrease at high altitudes. World-class athletes performing endurance exercises consistently seem to perform better if they train at a moderate altitude.

Acute and chronic effects of aerobic and resistance exercise on ambulatory blood pressure.
The acute inflammatory phase begins immediately after injury and lasts 24 to symptoms quotes cheap 4.5 mg rivastigimine visa 48 hours medications ok for dogs generic 1.5mg rivastigimine, although some aspectsmay continuefor up to treatment innovations order 4.5mg rivastigimine 3 weeks medications harmful to kidneys buy rivastigimine 1.5 mg visa. The proliferative phase may begin early in the inflammatory phase but is thought to be most extensive approximately 21 days after injury. The matrix formation/ remodeling phase begins 3 weeks after injury and may last for up to 2 years, although in many cases the majority of remodeling has occurred by 2 months. Blood vessels at the site of injury initially undergo vasoconstriction, which is mediated by norepinephrine and usually lasts from a few seconds to a few minutes. If serotonin is released by mast cells in the area of injury, a secondary prolonged vasoconstriction occurs to slow blood loss in the affected region. It is now recognized that numerous cytokines and growth factors are involved in the cellular response to inflammation and injury. Proinflammatory prostaglandins are believed to sensitize pain receptors, attract leukocytes to the inflamed area, and increase vascular permeability by antagonizing vasoconstriction. Which cell type is especially prominent in the proliferative and matrix formation phases of connective tissue healing? It is responsible for synthesizing and secreting most of the fibers and ground substance of connective tissue. Soft tissue injury signals the fibroblast to multiply rapidly and mobilizes free connective tissue cells to the injured area. Tissue bleeding, in the case of trauma-induced inflammation, will result in deposition of fibrin and fibronectin in the tissues. These substances form a substratum that enhances the adhesion of various cells during later stages of repair. Enzymes and hormones also play a role in tissue healing, as do mechanical stress and infection. Steroids suppress the mitotic activity of fibroblasts, which results in diminished deposition of collagen fibers and reduction in tensile strength. Antibiotic medicines inhibit protein synthesis and may adversely affect wound healing and scar formation. Disease processes such as diabetes mellitus significantly retard wound healing because small-vessel disease inhibits normal collagen synthesis. What is the association of antibiotic medicines and acute tendinopathy and tendon ruptures? Tendon rupture is nearly always preceded by spontaneous onset of pain within 2 to 3 cm of the insertion point, thought to be closely correlated with reduced vascularization at this site. Other tendons reported to be affected include the biceps brachii, supraspinatus, and extensor pollicis longus. Whether dietary supplements such as glucosamine have a significant and lasting effect on joint disease has not been well established in controlled clinical trials, though mounting evidence suggests that such supplements are beneficial. Recent studies indicate that glucosamine may limit the advancement of joint space narrowing associated with osteoarthritis, resulting in improved functional scores. Despite these differences, many of which have been confirmed in animal studies, clinical experience indicates that older patients often undergo surgical treatment with no adverse healing responses related to aging. Historically, painful tendon conditions were referred to as tendinitis and were assumed to be an inflammatory condition. Over time, however, further analysis revealed that the condition was not attended by inflammatory cells but was a degenerative change in the tendon?more accurately referred to as overuse tendinosis. The pathology of tendinosis is characterized by a loss of collagen continuity and an increase in ground substance, vascularity, and cellularity. Research indicates that substance P, a neuropeptide known to contribute to tendon pain, is upregulated with tendon overuse. The cellularity increase associated with tendinosis results from fibroblasts and myofibroblasts, but inflammatory cells are absent. Because of this new understanding, it has been recommended that the term tendinopathy replace the term tendinitis for describing tendon pathology. However, because tendinosis is by definition a chronic condition, treatment usually focuses on a controlled eccentric training program, often lengthy (10 to 12 weeks or more in some cases) in duration. For Achilles tendinopathy, the most widely adopted approach is the Alfredson protocol of eccentric heel-drop exercises. This high-volume regimen has been shown to be particularly effective in athletic patients, though less so in nonathletic and older patients. Evidence clearly points toward exercise and mechanical loading as the best documented strategy for treating patients with tendinosis. Changes that result in this alteration include an increased density of cells (usually fibroblasts), the presence of myofibroblasts, a reduction in hyaluronic acid and chondroitin sulfate levels in the periarticular connective tissue, and a 4% to 6% reduction in water content of the same tissues after only 9 weeks of immobilization. At the same time a significant increase in the intermolecular cross-links of collagen leads to contracture formation. Therefore the remodeled connective tissue after immobilization is both thicker (tendency toward contracture) and weaker, possibly because of the random alignment of collagen fibers. Many studies have documented that scar tissue forms earlier in mobilized tendons, is well oriented, and is not attended by adhesions, in contrast to scar tissue that develops without physiologic stresses. Exposure of scar tissue to physiologic tensile forces during the healing process results in a more mature and stronger union of tendon and ligament. This response appears to be time-dependent and may be related to limiting the inflammatory response and encouraging fibroplasia and fibrillogenesis. After ligament and tendon repair or reconstruction, when is the soft tissue the strongest and when is it the weakest? Much of the information related to this question has been derived from studies using animal models (primates and others) and should be interpreted with caution. General data indicate that the strength of the patellar tendon autograft used in anterior cruciate ligament reconstruction cases is strongest on the day that it is surgically implanted. As the tissue heals in its new location, its strength diminishes to significantly <50% during the first 4 to 8 weeks postoperatively. The clinical implications are fairly straightforward: protect the graft in the early stages of rehabilitation, encourage closed-chain axial loading activity to minimize shear forces (joint translation), and emphasize maximal motor unit activation throughout the rehabilitation process. What is the response of articular cartilage to chondroplasty (microfracture technique, abrasion, and drilling) of the undersurface of the patella? The microfracture technique is used to stimulate tissue repair of full-thickness articular cartilage defects. This hybrid repair tissue may be functionally better than fibrocartilage alone; early animal and human studies suggest that it is durable enough to function like articular cartilage. Reproduced chondrocyte cells harvested from the patient are injected under a periosteal flap covering the articulardefect. Two-yearfollow-upstudiesof patientswith femoral condyletransplantsindicate excellent results; most patients developed hyaline-like cartilage in the defect site. Research is encouraging for focal chondral defects but not for generalized osteoarthritis of the joint. In addition, there is evidence that articular cartilage exposed to electric and electromagnetic fields can lead to a sustained upregulation of growth factors, enhancing its viability. Less radiation (2 megarad) in combination with ethylene oxide will decrease graft strength.

Once the nerve has left the region of the fibular head and entered the anterior compartment symptoms women heart attack order generic rivastigimine from india, it is relatively protected and rarely entrapped treatment wetlands rivastigimine 4.5 mg cheap, apart from problems associated with the anterior compartment symptoms 3dpo purchase 4.5mg rivastigimine free shipping. Again symptoms of the flu generic 1.5 mg rivastigimine with amex, distinguishing between a deep fibular nerve mononeuropathy and an L5 radiculopathy is paramount for both the clinical and the electrophysiological examinations. Anatomically, a compartment is created with the tibia medially, the fibula laterally, the interosseous membrane posteriorly, and a tough fascial layer anteriorly. Insults that involve this compartment can affect deep fibular nerve or anterior tibial artery function or muscle tissue directly. Examples range from anterior tibialis strain (shin splints: a mild form of anterior compartment syndrome) to muscle inflammation secondary to prolonged exercise, direct trauma to the leg, snake bites, or arterial bleeding. Significant increases in pressure are treated with fasciotomy?an incision of the anterior fascia of the leg. The most common presentation involves only the sensory component; numbness and tingling are identified in the web space between the great and second toes. Symptoms involving the plantar nerves include pain, burning, and paresthesias, often in the distribution of one or both plantar nerves. Recent studies have demonstrated effective techniques that facilitate the electrophysiologic examination of this region, including the medial plantar nerve, lateral plantar nerve, and the medial calcaneal nerve. The focus of these procedures has been to improve the consistency of the measurements and electrophysiologic signals. In general, passage through the fascia of the leg is not a common site of entrapment; thus sural nerve compressions are relatively rare. A decrease in nerve conduction velocity in this nerve as well as other major nerves of the leg (eg, tibial and deep peroneal) suggests polyneuropathy. Most of the work investigating sensitivity and specificity in electrophysiologic testing has been conducted in the upper extremities, with values of greater than 85% sensitivity and 95% specificity reported for entrapments of the median nerve at the wrist. Other researchers have found, for the median nerve, the composite electrophysiologic measures for sensitivity range between 49% and 84%, with specificity values of 95% or higher reported. Assuming that these values can be applied to lower extremity entrapments, they indicate that although the electrophysiologic tests are quite good, they are not perfect. Are there regions of the lower extremity that have a tendency to generate electrophysiologic false positives? These abnormal electrophysiologic findings additionally appeared to increase with age, being most noticeable in individuals over the age of 60. A second muscle examined, the fibularis (peroneus) tertius, also demonstrated positive findings in normal subjects over the age of 60 but at a much lower rate of 9%. Other studies have demonstrated a much more conservative prevalence of only 2% when examining foot intrinsics in normal subjects. What neurologic conditions should be considered in patients with bilateral lower limb numbness, tingling, and pain? In severe sciatic nerve injuries, patients will also exhibit (in addition to weak ankle dorsiflexion) weak ankle plantar flexion and knee flexion, decreased ankle jerk reflex, and sensory loss of the lateral leg and dorsal and plantar aspects of the foot. Sciatic nerve injury can occur up to 3% of the time following total hip replacement. The next most common injuries are external compression and penetrating injuries (ie, gunshot, knife, injections). Least common are tumors in adults; however, in the pediatric population a tumor is the most common cause of sciatic neuropathy. What are common nerve conduction and electromyography findings in patients with sciatic nerve injury? Because sciatic nerve injuries most often involve the fibular portion versus the tibialportionofthesciaticnerve,the fibularmotornerveamplitude willbesignificantlyreduced,andthe tibial nerve and tibial H-reflex will demonstrate normal or near normal values. Muscles showing denervation will primarily be fibular innervated muscles (94%?100% of patients), such as the biceps femoris short head and pretibial and lateral lower leg compartment muscles. Tibial innervated muscles (medial hamstring muscles, posterior and medial leg compartment muscles) can and will be involved in severe sciatic nerve injuries (74%?84% of patients). However, most individuals have a good outcome 3 years following injury, whereas 30% of individuals sustaining sciatic nerve injury have near normal function 1 year post injury. The best outcomes occur in those patients with a common fibular nerve conduction response that is obtainable from the extensor digitorum brevis muscle and the absence of paralysis of the pretibial and/or posterior compartment muscles.

Tourniquet related iatrogenic femoral nerve palsy after knee surgery: Case report and review of the literature. In a patient with footdrop (ie, weakness of ankle dorsiflexors and toe extensors), the clinical and electrophysiologic evidence distinguishing between a common fibular nerve (peroneal nerve) mononeuropathy and an L5 radiculopathy is: a. Following a routine arthroscopic knee surgery, a patient reports loss of sensation along the medial aspect of the lower limb. The midfoot (lesser tarsus) consists of the navicular (or scaphoid), cuboid, and 3 cuneiforms (medial, intermediate, and lateral). The medial column is composed of the talus, navicular, 3 cuneiforms, and metatarsals 1 to 3, along with their respective phalanges. The lateral column consists of the calcaneus, cuboid, and metatarsals 4 to 5 along with their respective phalanges. What are the four muscular layers, from superficial to deep, from the plantar aspect of the foot? Although compensations may occur in the lower limb, pelvis, or lumbar spine to accommodate for a restricted talocrural joint, approximately 6 to 10 degrees of dorsiflexion and 20 to 30 degrees of plantar flexion are required for normal gait. Although compensations may occur in the lower limb, pelvis, or lumbar spine to accommodate for a restricted subtalar joint, a total of 4 to 6 degrees of inversion/eversion is generally required for normal gait. What is the correct terminology to use when referring to or describing foot and ankle motion? Itiscorrecttousethesuffix us?or ed?whendescribingorreferringtoastaticposition(eg,supinatusor pronated) and ion and ing when describing or referring to motion or a movement (eg, supination or pronating). In weight bearing, pronation occurs at initial contact through the loading response during gait. Internal rotation of the lower leg produces talar adduction and plantar flexion relative to the calcaneus, and the calcaneus everts and abducts. This process typically occurs during the first 25% of the stance phase of gait, as the foot adapts to the ground. Supinationduring gait occurs from the start of the midstance phase of gait (foot flat) throughterminal stance. This process occurs as the lower leg starts to rotate externally, leading to talar abduction (dorsiflexion relative to the calcaneus), and the calcaneus inverts and adducts. In the nonweight bearing or swing phase, the talus is relatively fixed in the ankle mortise, and supination/pronation occurs through the subtalar joint by movement of the calcaneus and foot around the subtalar joint axis of motion. In supination, the calcaneus and foot move through a combination of inversion, adduction, and plantar flexion in relation to the fixed talus. In pronation, the calcaneus moves through eversion, abduction, and dorsiflexion relative to the fixed talus. The windlass mechanism of the foot refers to the seemingly simple maneuver of dorsiflexion of the toes of the foot, most specifically related to passive hallux extension that elevates the medial longitudinal arch through hindfoot supination when the calcaneus inverts.
Symptoms and signs include weakness medicine 2016 generic rivastigimine 3mg free shipping, sweating symptoms graves disease cheap rivastigimine 3mg otc, tremors treatment 02 binh discount 3 mg rivastigimine free shipping, tachycardia medications 230 purchase rivastigimine overnight delivery, headache, confusion, seizure, and coma. The 3Ps are used to remember symptoms of hyperglycemia: polydipsia, polyphagia, and polyuria. Platelets are necessary for blood clotting and contribute to vascular integrity, adhesion, aggregation, and subsequent platelet plug formation. Symptoms include mild to severe hemorrhage, petechiae, purpura, epistaxis, hematuria, bruising, menorrhagia, and gingival bleeding. This can be a primary (essential thrombocythemia), secondary (eg, leukemia, myeloma, polycythemia, splenectomy, hemorrhage, infections, or drugs), or transient process (after exercise, stress, or epinephrine injection). Routine blood testing measures only the small extracellular portion and not total body potassium. K+ levels are influenced by acid-base status, hormone status, renal function, gastrointestinal loss, and nutritional status. Values greater than 1:80 are significant; values of 1:640 and higher can be seen in rheumatoid arthritis. Renal blood flow, carbonic anhydrase activity, aldosterone, pituitary hormones, renin, and antidiuretic hormone are important in sodium homeostasis. There are many causes: 1) hypotonic (isovolemic, hypovolemic, or hypervolemic); 2) isotonic; or 3) hypertonic. A patient with low serum sodium levels, tachycardia, hypotension, vomiting, diarrhea, and diuretic use has what form of hyponatremia? Both sodium and water are increased, but water is increased proportionally more than sodium. A 70-year-old male taking medication for hypertension and diabetes develops profound muscle weakness after 4 days of vomiting and diarrhea. Severe hemorrhage, petechiae, purpura, epistaxis, hematuria, and bruising are signs of which condition? Its purposeis to test the integrity of the myelin sheath of motor (efferent fibers) and sensory (afferent fibers) portions of the peripheral nervous system. It identifies normal or abnormal physiologic findings by location and by characteristics and offers information regarding prognosis. The most common referral seen from the primary care setting is an evaluation for an entrapment neuropathy (eg, carpal tunnel syndrome or ulnar neuropathy at the elbow). The next most common referral is to differentiate between bilateral lumbosacral radiculopathies caused by spinal stenosis and peripheral polyneuropathy. They are also invaluable for diagnosing primary muscle disease, including muscle weakness that may occur as a major side effect from the pharmacologic management of hyperlipidemia (use of statin drugs). They can be extremely helpful when pain is associated with numbness, tingling, and/or weakness. It is calculated by dividing the distance between two points of stimulation by the time it took for the nerve impulse to travel between these two points. Abnormal insertional activity may be reported as increased (>200 ms reflecting acute muscle cell membrane instability) or decreased (<50 ms reflecting a loss of electrical viability of the muscle cell membrane). The spontaneous appearance of positive sharp waves and fibrillation potentials indicates an acute process of muscle cell membrane instability and may be present in neuropathic or myopathic conditions. Other abnormal spontaneous discharges include waxing and waning discharges, complex repetitive discharges and fasciculations that indicate chronicity. A normal motor unit has four phases or less (times crossing the baseline), is less than 5 mV in amplitude, is more than 5 ms and less than 16 ms in duration, and fires at a frequency of less than 10 Hz. A neuropathic motor unit may have more than four phases (polyphasic), greater than 5 mV in amplitude (larger than normal amplitude), greater than 16 ms in duration (wide duration), and/or fires faster than 10 Hz before recruitment of the next motor unit. V in amplitude (low amplitude), less than 5 ms in duration (short duration), and fire many motor units with minimal effort. A neuropathic condition would exhibit reduced motor unit recruitment along with a loss of firing voluntary motor units. A myopathic condition would exhibit early motor unit recruitment (unable to isolate individual voluntary motor units well) along with a loss of medium (2?3 mV) to large (4?5 mV) amplitude motor units. When the amplitude is within normal limits, this suggests the existence of a disease process or injury of the myelin (see focal demyelinating process below). Distal Latency Amplitude Conduction Velocity Upper Limb Motor nerve (8-cm distance) <4. Radiculopathies are nerve injuries that are preganglionic (proximal to the dorsal root ganglion). In a completely severed nerve or when severe conduction block is present, voluntary motor units are absent in muscles innervated by the nerve distal to the lesion site. Although the anterior horn cell along with its axon and neuromuscular junctions remains intact, the loss of muscle fibers results in short-duration low-amplitude motor units. The pattern of myopathic abnormalities is typically confined to the most proximal muscles of the limbs and trunk and is symmetric. The surviving motor units have larger than normal amplitudes (>5 mV) and wide durations because they sprout to capture denervated muscle fibers within their territory (reinnervation). The pattern of abnormalities is typically confined to a specific peripheral nerve distribution (root, plexus, nerve) or may be distal and symmetric when disease is present. This is caused by pathologic changes in the acetylcholine receptors on the postsynaptic side of the neuromuscular junction that block the transmission process and cause motor weakness. It is performed by stimulating the peripheral nerve and recording through multiple channels at more proximal segments along the nerve, including one or more sites along the spine and at the somatosensory cortex. It requires 5 to 10 days for injured peripheral nerves to deteriorate completely because of wallerian degeneration distal to the suspected lesion. Nerve conduction distal to the lesion may look normal immediately after nerve severance and continueto look relatively normal for up to 3days. A preserved evoked amplitude present 4 days after the onset of the lesion has a good prognosis. What is wallerian degeneration, and how long does it take a peripheral nerve lesion of this type to recover? Wallerian degeneration is disruption of the myelin and axons along the entire length of the nerve below the site of the lesion. Because the epineurium remains intact, nerve regeneration can readily take place in a health body. The approximate rate of nerve regeneration is 6 mm per day for a root level lesion, 2 mm per day for a forearm level lesion, and 1 mm per day for a hand or lower leg level lesion. Manual muscle test demonstrated 2/5 strength of dorsiflexion, eversion, toe extension, and great toe extension. The remainder of the muscles selected for study including the short head of the biceps femoris, tibialis posterior, and lumbosacral paraspinal muscles were normal. There were no positive sharp waves or fibrillation potentials seen at rest in all muscles tested. A repeat test 17 days later recorded a conduction velocity of 28 m/sec from the deep fibular nerve across the fibular head segment and 40 m/sec distal lower leg segment. V with stimulation above the fibular head and 3 mV with stimulation below the fibular head. From the information given previously, can you locate and describe this nerve injury and give a prognosis? Focal demyelination is confirmed by the isolated slowing of the deep fibular nerve across the fibular head segment. Acute denervation is confirmed by the presence of positive sharp waves and fibrillation potentials along with reduced motor unit recruitment in the right common fibular nerve distribution below the branch to the short head biceps femoris. Prognosis is good and it is estimated that recovery will take around 2 to 3 months.
