Clinical Trial Summary

This study will use electromyography and nerve conduction studies to evaluate median nerve function during the Phalen's wrist flexion test in different wrist positions.

Description:

The Phalen's test is commonly used to assess carpal tunnel syndrome. However, it is unclear which wrist position during this test best isolates median nerve function. This study will measure thenar muscle activation and median nerve conduction in 30 healthy participants performing the Phalen's test. Different wrist flexion angles will be evaluated to determine which position optimally targets the median nerve. Results may enhance utilization of the Phalen's test in clinical practice and research.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Thenar Muscle Activation	Mean EMG activity of the thenar muscles during the Phalen's test at different wrist angles. Measured in microvolts (µV).	Baseline
Primary	Median Nerve Conduction Velocity during Phalen's Test	Median nerve conduction velocity (measured in meters per second, m/s) assessed using surface electrodes at the wrist and elbow during the Phalen's test wrist flexion maneuver. Measured bilaterally at each wrist flexion angle during a single study visit.	Baseline
Primary	Median Nerve Distal Latency during Phalen's Test	Median nerve distal latency (measured in milliseconds, ms) assessed using surface electrodes over the abductor pollicis brevis and stimulating the median nerve at the wrist during the Phalen's test. Measured bilaterally at each wrist flexion angle during a single study visit.	Baseline
