Objective:To develop a staged exercise prescription for patients with Knee Osteoarthritis (KOA) based on internet information systems and evaluate its effectiveness, in order to provide a reference for exercise rehabilitation guidance for KOA patients.Methods:A systematic review of guidelines, expert consensus, systematic reviews, and evidence summaries on exercise prescriptions for osteoarthritis from January 1, 2012, to December 31, 2022, was conducted. After literature screening, semi-structured interviews, and expert consultations, a staged exercise prescription for KOA patients based on internet information systems was formulated. From April to October 2023, 90 KOA outpatients from Beijing Friendship Hospital, Capital Medical University, were selected using convenience sampling and randomly divided into the observation group and the control group, each with 45 cases. The control group received routine rehabilitation nursing, while the observation group implemented the staged exercise prescription based on the internet information system. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Multidimensional Self-Efficacy for Exercise Scale (MSES) were used for evaluation before the intervention and at 4, 8, 16, and 24 weeks post-intervention. After the intervention, the Exercise Adherence Rating Scale (EARS) was used to assess exercise adherence in both groups.Results:A staged exercise prescription consisting of three phases and 27 items was successfully developed. At 8, 16, and 24 weeks after the intervention, the observation group had significantly lower scores in the pain, stiffness, and daily activity dimensions of the WOMAC compared to the control group, and the differences were statistically significant ( P<0.05). At the same time points, the observation group had significantly higher MSES scores than the control group, and the differences were statistically significant ( P<0.05). At 16 and 24 weeks post-intervention, the EARS scores of the observation group were also significantly higher than those of the control group, with statistically significant differences ( P<0.05) . Conclusions:The staged exercise prescription for KOA patients based on internet information systems is both scientifically valid and feasible. It can effectively alleviate knee joint symptoms, enhance exercise self-efficacy, and improve exercise adherence.

Objective:To explore the application effect of lower limb strength training based on "Internet +" in the home rehabilitation of knee osteoarthritis (KOA) patients.Methods:Using the convenient sampling method, a total of 80 KOA patients who visited Pain Outpatient Department of Beijing Friendship Hospital, Capital Medical University from May 2021 to December 2022 were selected. They were randomly divided into the observation group and the control group by the random number table method, with 40 cases in each group. The control group adopted routine home rehabilitation nursing, and the observation group implemented lower limb strength training based on "Internet +" on the basis of the control group. Both groups were intervened for 3 months, and the knee joint pain degree (VAS score), knee joint function (KOOS score) and exercise compliance of the two groups were compared.Results:After intervention, the VAS score of the observation group was lower than that of the control group and the KOOS score was higher than that of the control group, and the differences were statistically significant ( P<0.05). There were 26 cases of high compliance, 11 cases of partial compliance and 3 cases of low compliance in the observation group, and 19, 10 and 11 cases in the control group, respectively. The exercise compliance of the observation group was better than that of the control group, and the difference was statistically significant ( Z=1.997, P=0.046) . Conclusions:The implementation of lower limb strength training rehabilitation management based on "Internet +" can effectively alleviate knee pain in knee osteoarthritis patients, improve knee function, and improve their compliance with home exercise.

In view of the high incidence of malignant diseases such as malignant arrhythmias in the elderly population, accidental injuries such as falls, and the problem of no witnesses when danger occurs, the study developed a human vital signs and body posture monitoring and positioning alarm system. Through the collection and analysis of electrocardiogram (ECG), respiration (RESP) and acceleration (ACC) signals, the system monitors human vital signs and body posture in real time, automatically judges critical states such as malignant arrhythmias and accidental falls on the local device side, and then issues alarm information, opens the positioning function, and uploads physiological information and patient location information through 4G communication. Experiments have shown that the system can accurately determine the occurrence of ventricular fibrillation and falls, and issue position and alarm information.
