Upper Limb Nerve Entrapment Syndromes in Veterans With Lower Limb Amputations
Pm&r, 2010Co-Authors: Paul F. Pasquina, Michael Demarco, Robert Wallach, Emily Teodorski, Rory A. CooperAbstract:Objective To examine the prevalence and severity of upper limb entrapment syndromes in a sample of veterans with lower limb amputations. Design A descriptive survey, pilot study. Setting 2008 National Disabled Veterans Winter Sports Clinic. Participants Twenty participants with various lower limb amputations. Methods All study participants completed a questionnaire that included symptoms of both upper limbs, medical history, time since amputation, medication history, use of assistive technology, and wheelchair characteristics. A physical examination and electrodiagnostic testing were then performed on each participant. The physical examination included an assessment of bilateral upper limb weakness or sensory abnormalities, thenar/hypothenar atrophy, deep tendon reflexes, Tinel test of the wrist and elbow, and the Phalen Maneuver. All nerve conduction studies were performed by an American Board of Electrodiagnostic Medicine-certified physiatrist. Outcome Measures Correlation between symptoms, examination findings, and electrodiagnostic findings with the participant's demographic data in the questionnaire. Results Twenty participants (19 men and 1 woman) were enrolled in the study, with a total of 38 upper limbs evaluated. The mean age of the study population was 59 ± 13 years, with an average of 23 years since the amputation. Sixteen (80%) of 20 participants had electrodiagnostic findings consistent with median neuropathy across the wrist (26/38 affected limbs, 6 participants with unilateral and 10 with bilateral findings), and 14 (70%) of 20 participants had ulnar entrapment neuropathy across the elbow (22/38 affected limbs, 6 participants with unilateral and 8 with bilateral findings). Several participants (6 of 20, 30%) were found to have electrodiagnostic evidence of ulnar entrapment neuropathy across the wrist (10 of 38 affected limbs, 2 participants unilateral and 4 bilateral findings). Conclusion A high number of veterans with lower limb amputations presented with upper limb nerve entrapment syndromes. Careful attention to these nerve entrapment syndromes in lower limb amputees is necessary because the symptoms may be confounded by other chronic pain-related disorders.

Clinical and electrophysiological findings in carpal tunnel syndrome
Brain and nerve, 2007Co-Authors: Nobuo KoharaAbstract:Carpal tunnel syndrome (CTS) is the most common nerve entrapment disorder. The clinical features of CTS are variable, but usually include pain and paresthesia in the thumb, first two fingers, and the radial-half of the ring finger. Paresthesia and sensory deficits might involve the entire palm area in some cases. Pain frequently radiate proximally into the forearm, and occasionally to the shoulder. Many patients experience pain at night and are awakened by abnormal sensations. Shaking hand relief the symptom. The two classic tests for nerve compression at the wrist are the Tinel test and the Phalen Maneuver, which diagnostic value is limited. Golden standard for the diagnosis is the combination of the clinical findings and the electrophysiological study. Routine median nerve conduction study is valuable. Prolonged terminal latency of motor or sensory nerve would be found in most CTS hands. If the routine study showed equivocal, more sensitive methods are needed. Those include segmental sensory conduction study across the carpal tunnel by median stimulation at midpalm, a comparison of median and ulnar sensory nerve latencies at ring finger and a comparison of median and radial sensory nerve latencies at thumb. A difference between the median motor latency to the second lumbrical and the ulnar motor latency to the interossei muscles has also diagnostic value in some cases. In addition, inching method can localized the compression site. Using these techniques, the diagnosis of CTS would become more reliable.
