What is the study measuring?

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Adherence percentage outcome was measured with the self-report | The participants received an online exercise log via WhatsApp message and were asked to record the date and number of the exercise session | baseline and see the change after 6 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| VAS | a single-item continuous scale composed of a horizontal or vertical line (Hawker et al., 2011). The score is determined by measuring the distance (in mm) on a 10-cm line between the no pain (score of 0) anchor and the patient's mark (evaluating their pain), providing a range of scores from 0-to 10. A higher score of 10 indicates higher pain intensity. | baseline and see the change after 6 weeks | 
| WOMAC | The WOMAC is a disease-specific self-report instrument with 17 items in Physical Function. It has been extensively used; it is valid, reliable, and widely recommended in studies of individuals with knee OA, (score range 0-68 where 68 indicates worse function. | baseline and see the change after 6 weeks |
