The aim of this study is to determine the clinical efficacy of gait rehabilitation robot through cortico-spinal-muscular pathway activation of the muscles remotely located from the end-effecter in patients after total knee arthroplasty.
pre-interventional evaluation; within 1 day of intervention start primary end point; 3 days after intervention start secondary end point; 5 days after intervention start
