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

This study investigates how the human motor cortex contributes to muscle recruitment for gravity compensation during posture and reaching, finding that motor evoked potentials correlate with postural muscle moments.

This study shows that primary afferent feedback cannot replicate the dynamic muscle activity patterns during reaching movements, suggesting that task-dependent muscle co-activation and nonlinear feedback are key to controlling limb dynamics.

The paper validates and scales musculoskeletal models of the human forearm and hand using posture-dependent moment arms, isometric force measurements, and error detection to improve accuracy in torque prediction.
