Effects of Wii balance board exercises on balance after posterior cruciate ligament reconstruction

The aim of this study was to establish the effects of training on Wii balance board (WBB) following posterior cruciate ligament (PCL) reconstruction on balance. Included patient injured her posterior cruciate ligament 22 months before the study. Training on WBB was performed 4 weeks, 6 times per week, 30-45 min per day. Center of pressure (CoP) sway during parallel and one-leg stance, and body weight distribution in parallel stance were measured. Measurements of joint range of motion and limb circumferences were taken prior to and following training as well. Following training, the body weight was almost equally distributed on both legs. Decrease in CoP sway was most significant for one-leg stance with each leg on compliant surface with eyes open and closed. The knee joint range of motion increased and limb circumferences were reduced.

According to the results of this single case report, it could be recommended that the use of WBB be considered for balance training following PCL reconstruction.
