Development and reliability of a new system for bedside evaluation of non-volitional knee extension force.

Purpose: Neuromuscular electrical stimulation (NMES) is a widely-used technique for diagnostic and therapeutic purposes. Here we developed and tested the reliability of a new NMES-dynamometer system for bedside evaluation of knee extensor muscle function.

Materials And Methods: Thirty-two healthy participants (16 men, 16 women; 27±5 years) completed two testing sessions, 7 days apart.
