  1. LK- Left Knee; RK - Right Knee
  2. Mean = averaged across the session, SD = Standard deviation
  3. Session 1 was performed with the Fixed stiffness and Manual trigger; Session 2 & 3 with variable stiffness and BMI trigger
  4. aNumber of trials missed = Total trials-gait trials performed
  5. bResponse time = Onset of BMI trigger- Movement Attempt state
  6. cTrials were interrupted due to temporal restrictions of the patient
