The purpose of this case study was to evaluate balance of individuals following total knee arthroplasty between 12 and 16 weeks postoperatively using the NeuroCom Balance Master® 6.1 system. Two unilateral total knee arthroplasty (TKA) subjects and ten age-matched control subjects participated in the study. All subjects completed a series of five assessments including weight bearing, limits of stability, walk test, step up and over, and sit to stand on the NeuroCom Balance Master® system. Results showed differences in the sit to stand and weight bearing tests with TKA subjects bearing more weight on nonsurgical leg. TKA subjects also differed from the control group in the walk test demonstrating a decreased walking velocity.
