Abstract:
Objective:To explore the effects of WeChat-based home exercise intervention on the rehabilitation of elderly patients with knee osteoarthritis (KOA) .Methods:A 24-week quasi-experimental research was conducted from August 2019 to January 2020. Totally 6 communities were selected from Haidian District, Beijing by convenient sampling and randomly divided into the control group ( n=3) and the observation group ( n=3) using the envelope method. Patients in the intervention group ( n=46) were received WeChat-based home exercise intervention (including knowledge explanation, exercise skill education, and behavioral motivation) , while patients in the control group ( n=43) received WeChat-based knowledge explanation. The objective knee function (including muscle strength of lower limbs, range of motion of knee joints, balance function, and mobility) and subjective KOA symptoms (including pain, stiffness, and difficulty in daily activities) were collected from the two groups of patients at 0, 8th, and 24th weeks. Results:Within 24 weeks of intervention, the muscle strength of both lower limbs of the two groups increased with time, and the improvement in the intervention group was better than that in the control group, and the difference was statistically significant ( P<0.05) . At the 8th and 24th weeks after intervention, the range of motion of knee joints in the intervention group improved better than the control group, and the differences were statistically significant ( P<0.05) . Within 24 weeks of intervention, the balance function of the two groups improved with time, and the improvement of the intervention group was better than that of the control group, and the difference was statistically significant ( P<0.05) . Within 24 weeks of intervention, the mobility of the two groups increased with time, but the intervention group had better mobility than the control group only in the 8th week, and the difference was statistically significant ( P<0.05) . There was no statistically significant difference in the total scores of the Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and scores of pain, stiffness, and difficulty in daily activities between the two groups in the 8th and 24th weeks ( P>0.05) , except the difficulty in daily activities between the two groups in the 24th week. Conclusions:WeChat-based home exercise intervention can improve the objective knee joint functions of elderly KOA patients, such as muscle strength of lower limbs, range of motion of knee joints, balance function and mobility, but it has no obvious effect on the subjective symptoms of patients.
