Abstract
Abstract
Background
Rehabilitation is one of the keys to success following total knee replacement (TKR). Many methods can be used to reduce knee forces during weight-bearing exercises.
Objectives
The purpose of this study is to assess the effectiveness of a walking support machine (Co-walk) in improving clinical outcomes in TKR patients.
Methods
62 TKR patients were equally and randomly divided into two groups: the control group (Non Co-walk) and the experimental group (Co-walk). Both groups followed a standard 45-minute rehabilitation program. The Co-walk received an additional 15-minute Co-walk session once a week for 6 weeks. Outcomes were measured at admission and at 2 weeks, 6 weeks, 3 months, and 6 months in TKR patients.
Results
Participants in the Co-walk group demonstrated significantly different scores on the TUG test (18.10 ± 6.45) and the WOMAC pain scale (13.29 ± 5.49) at 2 weeks, 6 weeks, and 3 months (p < 0.001). WOMAC and ROM were statistically significant in the Co-walk group (36.10 ± 13.78) at 2 weeks, 6 weeks, 3 months, and 6 months (p < 0.001). WOMAC stiffness scores were statistically significant in the Co-walk group (6.03 ± 3.62) at 2 weeks (p < 0.001). Postural control for patients in the Co-walk group showed significant improvement in position (Left 16[8.5(6.5–14.0)]and Right 11[10.0(3.0–24.0)]) at 2 weeks, 6 weeks, 3 months, and 6 months. The experimental group and control group showed no significant difference in LOS (p = 0.379).
Conclusion
Co-walk effectively improves outcomes during the early rehabilitation period. It may be better than physical therapy rehabilitation programs alone.
