Brief Summary

Osteoarthritis of the knee is a common, chronic joint pathology that causes participants to suffer from pain, dysfunction, and reduced quality of life. The goal is to improve the quality of life and rehabilitation of patients by making rehabilitation exercises electronic and the system can be personalized to their specific conditions. The focus of this study was on exercise interventions, and an interactive software was designed that combines repetitive motion and real-time feedback mechanisms. The software provides a series of rehabilitation movements that are specific to the characteristics of osteoarthritis of the knee in older adults, aiming to help participants gradually improve joint range of motion and muscle strength through exercise. The real-time feedback mechanism, on the other hand, monitors the participants' exercise status in real time through wearable devices, providing intuitive feedback to the participants to ensure that they perform the rehabilitation movements correctly, thus ensuring the scientificity and safety of the exercise. In this study, investigators designed an exercise assessment and exercise intervention system for patients with knee osteoarthritis. In the exercise assessment part, the study combines several tools. First, the WOMAC scale was used to systematically assess patients' joint pain, stiffness, and dyskinesia. Second, physical function tests are used to assess the patient's overall exercise capacity, including indicators such as the number of sit-ups and rises. In addition, a wearable device was designed in this paper for real-time collection of knee angle information.

Outcome Measures

Primary Outcomes (1)

  • University of Western Ontario and McMaster University Osteoarthritis Index (WOMAC)

    The WOMAC scale provides a better assessment of elderly and chronic patients. The scale consists of 3 dimensions: pain, morning stiffness, and dysfunction, with a total of 24 items, including 5 items for pain and 2 items for morning stiffness. The scale consists of 3 dimensions: pain, morning stiffness, and dysfunction, with a total of 24 items, of which 5 are for pain, 2 for morning stiffness, and 17 for dysfunction, and can be completed within 5-10 min.

EXPERIMENTAL

Through digital means, patients are able to execute a personalized exercise program based on their rehabilitation plan and incorporate digital assessment methods to receive real-time feedback and recommendations for adjustments. By providing a personalized rehabilitation program and regular telecare, the aim is to focus on the patient's rehabilitation needs in a holistic manner.

Interventions

The program plans to use rational mechanism to provide safe and targeted exercise interventions to patients at different stages of their lives through three aspects: education, motivation and feedback. Through real-time collection of knee function parameters, real-time feedback on the effect of exercise intervention, and tracking the changes in the functional status of patients' knee joints. On the basis of improving knee function, we further improve patients' compliance with exercise intervention. Considering the community scenario, we plan to use sensors and wearable devices to realize the function of the knee joint on the basis of the existing technology. wearable devices to realize the digital assessment of knee function to reduce patient's time and cost and improve efficiency. At the same time, this digital assessment will provide a basis for decision-making for patient self-management.
