Balance is a critical part of daily activities and essential for independent function. The purpose of this study is to determine if there is a balance difference between subjects at twelve to sixteen weeks following unilateral knee arthroplasty and normal community dwelling controls. This study measures balance ability using five functional tests from the NeuroCom Balance Master® 6.1 system. Twelve subjects between the ages of 65 and 80 were tested. The two case study subjects with total knee replacements were between 12 and 16 weeks post-operatively. The control group consisted often healthy community dwelling adults. Results showed noticeable differences between the two groups in weight bearing and walking speed.
