Objective To explore the effect of internet of things-based power bicycle training or quadriceps training alone on pain and quality of life in patients with knee osteoarthritis in a community setting. Methods Patients with knee osteoarthritis who were admitted to West China Hospital of Sichuan University between April and July 2022 were selected. They were randomly divided into a power bicycle training group, a quadriceps muscle training group and a control group by random number table method. The primary outcome was improvement in knee pain, assessed by the Numerical Rating Scale (NRS) score. The secondary outcome was health-related quality of life, assessed by the 36-Item Short Form Health Survey (SF-36) score. Outcomes were assessed at baseline and 4, 8, and 12 weeks after the initial intervention. The statistical analysis was conducted using generalized estimating equations. Results A total of 72 patients were included, with 24 in each group. There was no significant difference in age, gender or other demographic characteristics among the three groups (P>0.05). The results of generalized estimating equations showed that there were interaction effects (group × time) on the NRS score, SF-36 physical functioning score, SF-36 bodily pain score, and SF-36 vitality score (P<0.05), while there was no interaction effect (group × time) on the role physical score, general health score, social functioning score, role emotional score or mental health score of SF-36 (P>0.05). At baseline, there was no statistically significant difference in the NRS score or SF-36 scores among the three groups (P>0.05). After 12 weeks of intervention, the two training groups were better than the control group in the NRS score, SF-36 physical functioning score, and SF-36 bodily pain score, the power bicycle training group was better than the quadriceps training group in the NRS score, the power bicycle training group was better than the control group in the SF-36 social functioning score, and the differences were statistically significant (P<0.05). Conclusions In a community setting, 12 weeks of internet of things-based power bicycle training and quadriceps training can significantly improve joint pain, physiological function and physical pain indicators in patients with knee osteoarthritis, and the power bicycle training is better than the quadriceps training in improving the knee pain of patients.
The Chinese Guideline for the Rehabilitation Treatment of Knee Osteoarthritis (2023 Edition) were jointly developed by the Chinese Society of Physical Medicine and Rehabilitation and West China Hospital of Sichuan University, aiming to standardize the rehabilitation treatment of knee osteoarthritis (KOA). This article focuses on the 11 core clinical issues of KOA rehabilitation assessment and treatment in the above guidelines, with a focus on introducing rehabilitation strategies such as KOA rehabilitation assessment and treatment, and proposes multiple corresponding recommendations. While interpreting the guidelines, it provides reference and inspiration for professionals engaged in KOA diagnosis, treatment, and rehabilitation management in China to optimize the standardization and scientificity of KOA rehabilitation treatment and improve patients’ rehabilitation prognosis.
Objective To investigate the effects of ergometer cycling training based on the internet of things and quadriceps strengthening based on internet mobile phones on joint stiffness, function and walking ability in patients with knee osteoarthritis (KOA) in a community setting. Methods KOA patients attending West China Hospital, Sichuan University were selected between April and July 2022. The patients were randomly divided into ergometer cycling group, quadriceps strengthening group and control group (treated with traditional therapy) using a random number table method. The patient underwent a 12 week intervention. The Western Ontario and McMaster Universities Arthritis Index (WOMAC) scale, Timed Up and Go Test (TUG) were used to evaluate the degree of joint stiffness, joint function and walking ability of patients. Data was collected and evaluated before intervention and at 4, 8, and 12 weeks after the initial intervention.Results A total of 72 patients were included, with 24 cases in each group. There were interactive effects between group and time in WOMAC joint stiffness score, joint functional score and TUG test time (P<0.05). At 8 and 12 weeks after intervention, the joint stiffness scores of the ergometer cycling group and the quadriceps strengthening group were better than those of the control group. At 4, 8 and 12 weeks after intervention, the joint function scores of the ergometer cycling group and the quadriceps strengthening group were better than those of the control group (P<0.05). At 8, 12 weeks after intervention, the TUG test scores of the ergometer cycling group were better than those of the control group and the quadriceps strengthening group (P<0.05). Conclusions In a community setting, both 12-week Internet of thing-based ergometer cycling and internet video-based quadriceps strengthening were effective on improving knee stiffness and function in KOA patients and were superior to traditional methods, the two effects were comparable. Ergometer cycling is superior to quadriceps strengthening and traditional methods in improving walking ability.
