The Impact of Carpal Tunnel Syndrome on Ulnar Nerve: An Electro-Clinical Study

Abstract

Introduction: The paresthesias' spread to whole hand in carpal tunnel syndrome (CTS) raises the hypothesis of ulnar nerve involvement. We performed this study to verify this hypothesis.

Investigating the effects of volar wrist cock-up splint and dorsal lock wrist hand orthosis in reducing signs of carpal tunnel syndrome

“…Carpal tunnel syndrome (CTS) is the most common compressive neuropathy in the upper extremity, causes motor and sensory impairment in the median nerve distribution of the hand (1)(2)(3)(4)(5). The main symptoms of this disorder are sharp pain, parenthesis, dysfunction of the hand in coordination and gripping (1,6,7) that are often worsened by daily activities or at night (1,7,8).…”

“…The main symptoms of this disorder are sharp pain, parenthesis, dysfunction of the hand in coordination and gripping (1,6,7) that are often worsened by daily activities or at night (1,7,8). Frequent, forceful grasping and flexed wrist posture for a long time, or hand-held vibration tools were exposed subjects to CTS (1)(2)(3)7). To determine the sensory deficit of CTS, twopoint discrimination test, vibration, and monofilament testing were used (1,7,8).…”

“…To determine the sensory deficit of CTS, two-point discrimination test, vibration, and monofilament testing were used ( 1 , 7 , 8 ). The prevalence of this syndrome was estimated at about 9.2%–15.6% in females and 6%–11.3% in males ( 2 , 6 , 7 ). Age and gender are related to the incidence of CTS ( 7 ).…”

“…For motor and sensory nerve evaluation of this syndrome, electromyography (EMG) and nerve conduction velocities were used to diagnosis and define the severity of CTS (2,4,6,(9)(10)(11)(12)(13). The most common conservative non-surgical intervention of mild to moderate CTS in rehabilitation is to use night (static) splints.…”

Evaluation of axonal loss in ulnar sensory nerve fibers recorded from ring and little fingers secondary to idiopathic carpal tunnel syndrome in Egyptian patients

“…Guyon's canal (GC) syndrome is an uncommon peripheral neuropathy where the ulnar nerve is entrapped through the narrow canal at the wrist [2]. Many studies analyzed the possible ulnar nerve affection at the region of the wrist in CTS [1], which mainly involved sensory fibers, and that ulnar nerve conduction abnormality was augmented with the increase in the severity of CTS [3][4][5][6][7][8][9][10][11][12][13].…”
