The study was stopped due to delays in the development and updating of the AI-assisted application intended for use in the study. As no further progress could be made at this stage, the study was withdrawn.

This study aims to evaluate the effectiveness of an artificial intelligence (AI)-supported mobile application that supervises home-based exercise programs in patients with knee osteoarthritis. A total of 80 participants aged 40 to 80 will be randomly assigned to one of two groups: a mobile application exercise group or a home exercise booklet group. Both groups will receive the same standardized stretching, strengthening, and range of motion exercises designed for knee osteoarthritis. The mobile app provides real-time feedback and supervision using the device's camera and artificial intelligence algorithms to track and guide exercise performance.
Participants in the app group will perform exercises with supervision via the app interface, while the control group will follow the same exercises using printed instructions. Both groups will exercise 3 to 4 times per week for 4 weeks. The study will compare pain levels, physical function, and balance before and after the intervention using validated outcome measures such as the WOMAC Index and the Visual Analog Scale.
This study may help determine whether AI-supported digital tools can improve exercise adherence and outcomes in patients with knee osteoarthritis.

| AI-Supervised Mobile Exercise Program | Behavioral | This intervention involves the use of an artificial intelligence (AI)-supported mobile application that delivers a personalized exercise program to patients with knee osteoarthritis. The app supervises exercise execution in real time using the device's camera and AI algorithms to track movements, count repetitions, and assess form accuracy. The program includes stretching, strengthening, and range of motion exercises performed 3-4 times per week for 4 weeks. The app provides instructional videos, personalized feedback, reminders, and records user performance. No video or personal images are stored; only anonymized motion data are collected and securely stored. |
| Measure | Description | Time Frame |
|---|---|---|
| Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) | The WOMAC is a validated questionnaire used to assess pain, stiffness, and physical function in patients with knee osteoarthritis. It consists of 24 items: 5 for pain, 2 for stiffness, and 17 for physical function. Each item is scored on a 5-point Likert scale (0 = none to 4 = extreme), with a total score range of 0 to 96. Higher scores indicate worse symptoms. | Baseline and Week 4 |
| Visual Analog Scale (VAS) | Change in pain severity measured by the Visual Analog Scale (VAS; range: 0-10; higher scores indicate worse pain) at baseline and at 6 weeks. | Baseline and Week 4 |
| Timed Up and Go (TUG) Test | Baseline and Week 4 | |
| Functional Reach Test (FRT) | Baseline and Week 4 | |
| Single-Leg Stance Test | Baseline and Week 4 | |
| Exercise Execution Accuracy Assessed by Mobile Application | Accuracy of exercise adherence detection by the AI algorithm compared to physiotherapist assessment (% agreement) | Before and during the 4-week intervention |

| Booklet-Guided Home Exercise Program | Behavioral | This intervention provides patients with a standardized home exercise program in printed booklet format. The program includes the same evidence-based stretching, strengthening, and range of motion exercises used in the mobile application group, performed 3-4 times per week for 4 weeks. Participants receive one-time in-person instruction on proper form but no ongoing supervision or feedback during the program. Adherence and technique are self-monitored. |
