Impaired Modulation of Motor and Functional Performance in Patients after Total Knee Arthroplasty: A Prospective Observational Study

Figure 1

Overshoot during sit-to-stand task. Vertical ground reaction force (GRF) of a representative subject during sit-to-stand performed at maximum speed and 50% and 25% of the maximum speed. Overshoot (OS) was calculated for each repetition (maximum, 50% and 25% of the maximum) as the difference between GRF-peak and body weight.
