This study assesses the test-retest reliability of motor evoked potentials (MEPs) in lower-limb muscles, finding that reliability varies by muscle, stimulation intensity, and quantification method.

This study examines muscle activation patterns during bidirectional walking and finds that while rhythm generation remains stable, pattern formation changes with adaptive adjustments in activation timing and amplitude.

This study develops and validates a method to elicit cutaneous reflexes from proximal muscles via saphenous nerve stimulation in healthy adults, showing reliable and symmetrical responses below pain thresholds.

This study investigates the effect of higher stimulation rates on H-reflex size during conditioning, finding no rate-dependent depression and reliable reflex values at 2 Hz.

This study shows that H-reflex up-conditioning during sciatic nerve regeneration in rats improves H-reflex recovery and locomotor symmetry, while down-conditioning has no negative effect.

This study investigates whether bidirectional walking on a split-belt treadmill induces short-term gait adaptations, finding unilateral aftereffects in step length.

This study identifies the physiological mechanisms underlying event-related potentials (ERPs) in humans, finding that movement-related potentials are mainly due to endogenous additivity, while auditory evoked potentials are mostly from exogenous phase reset.

This paper develops a computational model to simulate neural networks and identify targeted neuroplasticity protocols that improve motor recovery after stroke.
