NCT05965791 | Unknown

• 1 other identifier: OT-PT-001
• Study Type: observational
• Target: 30
• Locations: 1 country
• Sites: 1

Brief 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.

Conditions

Carpal Tunnel Syndrome

Outcome Measures

Primary Outcomes (3)

• Thenar Muscle Activation

  Mean EMG activity of the thenar muscles during the Phalen's test at different wrist angles. Measured in microvolts (μV).

  Baseline

• 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

• 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

Study Arms (1)

Diagnostic Test: Phalen's wrist flexion test

Interventions
