Sensory NCS was performed in the neutral position and then the wrist was placed in flexion and 90 degrees of extension for 1 min. Onset and peak latencies and velocities, negative peak duration and area, and peak amplitude were measured. Results: The most sensitive parameters were onset latency (77%), and onset (72%) and peak velocities (72%) in neutral position. The flexion maneuver did not increase their sensitivity, however, negative peak area (10%) and amplitude (24%) sensitivities were higher in extended position than in neutral position. Conclusion: The most sensitive NCS parameters were onset latency, and onset and peak velocities in neutral position. The extension maneuver was more sensitive than neutral position.
