Summary
The purpose of this study is to determine if rehabilitation using weight-bearing biofeedback training following total knee arthroplasty (TKA) is more effective than standard rehabilitation methods in promoting weight-bearing symmetry through the lower limbs during functional activities such as sit-to-stand transfers and walking. Secondary outcomes of interest include functional measures and internal moment at the hip, knee, and ankle joints during sit-to-stand and walking.
Eligibility Criteria
Inclusion Criteria
- unilateral total knee arthroplasty, body mass index 45 minutes away from the outpatient rehabilitation clinic, surgical complication requiring an altered course of rehabilitation, inability to walk 30 meters without an assistive device or inability to rise from a chair without use of arms
