Quadriceps femoris muscle torques and fatigue generated by neuromuscular electrical stimulation with three different waveforms (original) (raw)

Neuromuscular electrical stimulation (NMES) is an effective tool for enhancing muscle performance in rehabilitation settings. This study compares the effects of three different waveforms (monophasic, biphasic, and polyphasic) on the isometric torque and fatigue of the quadriceps femoris muscles in a balanced cohort of men and women. Results indicate that monophasic and biphasic waveforms produced higher torque outputs and less fatigue compared to the polyphasic waveform, with male subjects displaying greater torque generation than female subjects. The findings suggest optimal stimulation parameters for NMES to enhance muscle performance with reduced fatigue.
