Effect of Game Based Balance Exercises on Rehabilitation After Knee Surgery: A Controlled Observational Study.

Does a rehabilitation protocol based on balance exercises using Serious Game improve walk performance in patients undergoing knee resection and reconstruction for bone primary tumor?. 30 patients undergoing modular prosthetic replacement, following a primary bone tumor, were consecutively enrolled. During each hospitalization a physiotherapy treatment was activated, included 25 min training phase aimed postural and proprioceptive control. In order to better evaluate the walking speed at one-year post surgery in the study group, data were compared with a group of 22 patients treated in a previous period, called the control group, collected retrospectively. The control group differed only for the type of physiotherapy treatment offered. No statistically significant differences emerged from the two groups, regarding baseline characteristics. Walking speed in the study group was improved compared to the control group with a median difference of 0.22 m/s (p = 0.022). A difference was also measured in the speed of centre mass, with a median reduction of 4.5 mm/s (p = 0.005) in the study group, showing an improvement in postural control in stand-up position. Exercises aimed at recovering balance and Serious Game should be proposed in order to improve motor performance and postural control in the medium and long term.
