BACKGROUND It is unclear whether mental simulation without actual muscle contraction associated with actual motion can increase the excitability of the spinal neural function. OBJECTIVE To determine the best method for mental simulation without actual muscle contraction, we analyzed the F-wave of thenar muscles after stimulating the median nerve by motor imagery whilst holding the sensor of a...

Abstract Background Injuries to the thenar muscle mass or branch of median nerve and resulting loss thumb opposition lead a massive impairment hand function. For decades, reconstructive approaches were based on tendon transfers. To broaden repertoire, we present free functional pronator quadratus flap as viable alternative for reconstruction provide specification its indication. We demonstrate ...

We report two cases of bilateral chronic exertional compartment syndrome (CCS) in the forearm and hand. Measurement of the intramuscular pressure was useful for diagnosis. These two cases illustrate that bilateral CCS should be suspected in patients complaining of bilateral exercise-induced pain in the anconeus muscle, the forearms, the thenar and hypothenar regions and in the first dorsal inte...

Three studies (1,3,5) followed the tendon and nerve gliding exercise protocol described by Totten and Hunter (6), one study utilized only the nerve gliding exercises (4), and another study utilized modifications of the tendon gliding exercises (2). Patients with severe thenar atrophy were excluded in all cases, though only two studies specifically stated inclusion criteria of intermediate stage...

cm x 10 cm in size, ulcerated in the center and covered with greenish slough were seen over the medial aspect of both arms [Figure 1], and left forearm, left thenar eminence, and medial aspect of the left flank. The edges of the ulcers were raised and overhanging. The surrounding skin was violaceous and indurated. Two unulcerated nodules were also seen over the back. There was no significant re...

INTRoduCTIoN Carpal tunnel syndrome is a most common peripheral compression neuropathy (1). It is caused by mechanical compression of the median nerve as it traverses the carpal tunnel of the wrist. Classic signs and symptoms are numbness of the lateral three digits and weakness of the thenar muscles due to atrophy (2). Important diagnostic tests include electromyography (EMG) and nerve conduct...

Absolutely and relatively refractory periods have been investigated in terminal median nerve axons and in thenar muscle fibres in a variety of pathophysiological conditions. Marked increased in refractoriness were produced by cooling to 20 degrees C. Nerve fibre refractoriness was more pronounced in older subjects and diminished in myotonic dystrophy. In contrast, no significant changes in musc...

background: few reports represent palmar cutaneous nerve neuropathy in the wrist due to a ganglion cyst. case presentation: a 25-year-old female was presented with a mass at volar side of the wrist and hypoesthesia at the base of thenar eminence. at ulrasonographic examination, a simple cyst was detected. sensory response of palmar cutaneous branch of median nerve was absent at the affected sid...
