ABSTRACT

In patients with total knee arthroplasty, the improvement of knee extensor muscle strength is an important factor in restoring stability, movement and function, and reducing pain. The purpose of this study was to investigate the effectiveness of cryotherapy to improve knee extensor strength and balance ability of total knee arthroplasty patients. In this study, 14 patients with total knee arthroplasty patients were recruited from a rehabilitation hospital. They were divided into two groups: a cryotherapy group (n=7) and a control group (n=7). They all received 30 minutes of continuous passive motion (CPM) and sit to stand training for 15 minutes and cryotherapy five times a week for two weeks. Knee extensor strength and balance ability were measured. Knee extensor strength was measured by Biodex system 3, balance ability was measured by Balancia software. To verify the difference in muscle strength and balance ability between groups, the pre-intervention value was set as a covariate and an analysis of covariance was performed. After the training period, the cryotherapy group showed a significant improvement in knee extensor muscle strength (p<0.05). There was no significant difference between groups in balance ability (p>0.05). This study examined the effect of cryotherapy on muscle strength and balance ability after rehabilitation exercise in patients with total knee arthroplasty. The cryotherapy after rehabilitation exercise was found to have an effect on muscle strength improvement. However, it did not affect the balance ability. Therefore, it is recommended to improve muscle strength by applying cryotherapy after rehabilitation exercise for total knee arthroplasty patients.
