Effects of resistance training with theraband on pain and quality of life in patients with knee osteoarthritis

Introduction: Joint pain, especially pain in the knee joint, is one of the most important problems that people with osteoarthritis report.The aim of this study was to determine the effects of resistance training with theraband on pain and quality of life in patients with knee osteoarthritis. Materials and methods: Twenty five patients with knee osteoarthritis with age range of 38 to 65 years old who had no history of any exercise during the past six months, and had no chronic conditions affecting on study outcomes were selected as study sample and randomly divided into two groups including experimental (n = 13) and control (n = 12) groups. The experimental group performed 8 weeks of resistance training, and the control group did not receive any intervention. SF-36 and Numeric pain rating scale were used to assess quality of life and pain, respectively. Finally, data were analyzed using SPSS software and independent t-test analysis. The level of significance was considered to be equal or less than 0.05. Results: The results of this study showed that after using intervention in the experimental group pain had a significant decrease compared to the control group (p=0.012). Also, eight weeks of intervention indicated a significant difference in the quality of life of patients with knee osteoarthritis between the control and experimental groups as it was increased in the experimental group compared to the control group(p=0.001). Conclusion: The findings of this study indicated that resistance training with theraband can reduce pain and enhance quality of life in patients with knee osteoarthritis.
