The effects of elastic band exercise on the pain, kinesiophobia, functional, and psychological status after total knee arthroplasty: a randomized controlled trial

Abstract

Introduction: Elastic band exercise not only improves muscle strength and elasticity, increases efficiency, balance, and quality of life but also decreases the injury risk. This study was conducted to determine the effect of elastic band exercise on pain, kinesiophobia, functional, and psychological status after total knee arthroplasty.

Methods: This study was conducted out between October 2019 and April 2020 as a randomized controlled experimental study with a total of 60 patients. Data collection tools in this study included a descriptive information form, visual analog scale, Tampa Kinesiophobia, WOMAC Osteoarthritis Index, and Beck Depression Inventory.

Results: Before intervention, the total score of VAS, WOMAC, Tampa Kinesiophobia, and Beck Depression showed no statistically significant difference between intervention group and control group. However, 4 weeks after intervention observed a statistically significant difference between the intervention and control groups in terms of VAS (U = 10,000; p < 0.001), WOMAC (U = 0.00; p < 0.001), Tampa Kinesiophobia (U = 221.5; p = 0.001), and Beck Depression means score (U = 112.5; p < 0.001). In addition, 4 weeks after the intervention, joint range and walking test assessments were statistically significant between the intervention and control groups (p < 0.001).

Conclusion: The results of the research showed that elastic band exercise had a positive effect on psychological and functional capacity.

Trial registration: This study is registered in the Clinical Trial Registry (registration number NCT04981106) Key points • Patients with total knee arthroplasty require rehabilitation exercise to avoid physical function weakness. • Elastic band exercise significantly reduces patients' fear of movement and depression. • Elastic band exercise activities facilitate significant physical motion function. • Elastic band exercise inspires the will of patients to engage in home rehabilitation exercise patients after total knee arthroplasty.
