Autonomous use of a visual biofeedback in early rehabilitation after total knee replacement. Pilot study design

Patients undergoing Total Knee Replacement (TKR) improve functional capabilities, but a lot of them show strength deficits and asymmetric patterns of movement. Early rehabilitation within the first five days improve short-term outcomes, in particular recovery of functional capabilities and levels of physical activity. Biofeedback in early rehabilitation after TKR is effective to improve gait symmetry, reduce pain and increase levels of physical activity. This pilot study aims to evaluate the effects of the autonomous use of a visual biofeedback, based on the use of inertial sensor (KARI, CoRehab, Trento, Italy), on patient outcomes in very short post-TKR period
