Background: Hand repetitive occupational motions have been linked with raised incidence of Carpal Tunnel Syndrome (CTS) which is characterized by deterioration of median nerve function. A change in wrist & fingers position has been associated with disruption in median nerve function.
Purpose of Study: The purpose of this study was to investigate the influence of wrist and fingers position on median nerve distal latency responses in healthy subjects.
Subjects: Sixty healthy participants aging between 30 to 50 years from both sexes were randomly assigned into 1 study group.
Methods: Measurements of median nerve motor distal latency using nerve conduction study from neutral wrist, 60º wrist extension and 60º wrist flexion positions, measurements of median nerve sensory distal latency from fingers extension and fingers flexion positions.
Results: Wrist extension was displayed as the most convenient position as it showed significant difference when compared with other wrist positions. Fingers extension position was displayed as the most convenient position as it showed significant difference when compared with fingers flexion position.
Conclusion: Wrist and fingers extension position was the most convenient position for assessment of median nerve. Both sensory and motor distal latencies were optimized in extension position when compared with other wrist & fingers position. Also preventing repeated and prolonged wrist and fingers flexion may reduce risk of carpal tunnel syndrome.
