A session of transcutaneous electrical nerve stimulation changes the input-output function of motoneurons and alters the sense of force

Abstract: It is often assumed that transcutaneous electrical nerve stimulation (TENS) has a transient effect on proprioception and motor control. We found that position, force, and touch perception were altered during TENS. However, the sense of force remained altered following TENS. As the discharge rate of motor units also increased in first dorsal interosseus (FDI) and abductor pollicis brevis (APB) muscles for the same force output following TENS, we suggest that their input-output function was altered, potentially causing a sustained decrease in performance in force-matching tasks.
