Abstract in brief

The study examined how healthy individuals' knee muscles react to different walking disturbances, using EMG to measure muscle activity during perturbed gait on a split-belt treadmill, with responses quantified through cocontraction and perturbation response values.
Results showed that while perturbations generally elicited small muscle responses, higher perturbation intensities increased activation in certain muscles, and various types of perturbations triggered different muscle activation patterns, especially in the rectus femoris and gastrocnemius muscles.
Overall, healthy participants exhibited minor adjustments in knee muscle activation during perturbations, providing insights into muscle stabilization mechanisms during gait that could inform future research on abnormal muscle activation in patients with knee issues.]
