Effects of Different Telerehabilitation Methods on Pain, Functional Limitation, Muscle Strength, Balance, and Quality of Life in Patients With Knee Osteoarthritis.

The aim of our study is; To compare the effectiveness of asynchronous and synchronous telerehabilitation programs on pain, functional limitation, muscle strength, balance and quality of life parameters in patients with knee osteoarthritis. 60 patients with knee osteoarthritis who applied to Marmara University Faculty of Health Sciences Physiotherapy and Rehabilitation Department will be included in our study. The treatment and evaluations to be made will be explained and their consent will be obtained with their signatures. Patients will be randomly assigned to the asynchronous telerehabilitation group (n= 30 patients) and the synchronous telerehabilitation group (n= 30 patients). In the asynchronous telerehabilitation group, the rehabilitation program will be carried out via a mobile application (Diabetex). The coordinator will forward the exercise programs prepared specifically for the patients to the relevant participants through the application. On the other hand, telerehabilitation in the synchronous group will be carried out via video conference (Zoom). Patients will be taken to video conference calls and will perform their exercises simultaneously under the guidance of the researcher. An exercise program including lower extremity strengthening and stretching exercises will be applied to all patients. In both groups, the exercise program will be applied 3 days a week for 8 weeks, 1 session per day and 45 minutes per session. All outcome parameters will be evaluated by a blinded assessor who has not seen patients before. Patients starting the rehabilitation program will be evaluated at the beginning of the study, at weeks 4, 8, and 16. The information of the patients participating in the study will be taken with the demographic data form. Pain in patients will be measured with the Visual Analog Scale, while the functionality of the patients will be evaluated with the WOMAC osteoarthritis index and the Lysholm Knee Scoring Scale. In addition, the affected qual
