Objective: To determine if the Nintendo Wii Fit is an acceptable adjunct to the rehabilitation therapy of outpatients following total knee replacement. Design: Randomized controlled trial. Setting: Outpatient clinic in a rehabilitation hospital. Participants: 30 outpatients following total knee replacements were randomly assigned to either a video game (VG) group (n=18) or an additional exercise (AE) group (n=12) for 15 minutes following their scheduled physiotherapy (PT) session, twice weekly. Interventions: VG group used the Wii Fit balance board to play games which encouraged lateral and multidirectional weight shifting, and provided visual feedback regarding postural balance. AE group performed lower-extremity strengthening and balance training exercises. Main Outcome Measures: Numerical Pain Rating Scale (NPRS), range of motion (ROM), 2-minute walk test (2MWT), timed standing (TS), Lower Extremity Functional Scale (LEFS), Activity-specific Balance Confidence scale (ABC), and patient satisfaction. Conclusions: There were 11 men (36.7%) and 19 women (63.3%) with a mean age of 70.7±8.9 years. There was no significant difference between age, sex, number of days since surgery on admission, or overall length of outpatient rehabilitation stay between VG or AE groups. There was also no significant difference between VG or AE groups for changes from admission to discharge in NPRS (P=.708), knee flexion ROM (P=.846), knee extension ROM (P=.648), 2MWT (P=.422), timed standing tasks (P=.262), LEFS (P=.223), ABC (P=.831), or patient satisfaction with therapy services (P=.201). These results showed no significant outcome differences between the VG and AE groups, suggesting that Nintendo Wii Fit is an acceptable adjunct to physiotherapy interventions for the outpatient total knee replacement population. These results are preliminary, and suggest that statistically significant differences might be detected with a larger sample size.
