Design outcomes

Primary

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

Secondary

Measure	Time frame	Description
VAS	baseline and see the change after 6 weeks	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.
WOMAC	baseline and see the change after 6 weeks	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.
