People with knee osteoarthritis often need regular physiotherapy sessions to reduce pain and improve movement. Attendance of in-person sessions can be difficult because of travel and time. This study aims to learn if combining in-person and video sessions using Zoom works for people with knee osteoarthritis. The main questions it aims to answer are :
The researchers will compare the use of one in-person session and one video session per week to the standard care of two in-person sessions per week.
Participants will :

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Hybrid Tele-rehabilitation | Experimental | participants will receive one in-person and one video session per week for 8 weeks. Both sessions include the same exercise program delivered by a physiotherapist. |
|
| Standard Rehabilitation | Active Comparator | participants will receive two in-person sessions per week for 8 weeks. All sessions include an exercise program delivered by a physiotherapist. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Hybrid Tele-rehabilitation | Other | In-person session: participants attend the session in physiotherapy clinic.They will receive exercises (attached in the study protocol document) under the physiotherapist's supervision, including watching and correcting exercise techniques. Video session: participants attend video session via Zoom platform (Zoom Video Communications, inc., USA), an accessible internet-based platform from any laptop or mobile device that offers a real-time video and audio communications. Participants will receive a Zoom link with a unique password. During the video session, the physiotherapist accesses from the clinic using a laptop, while participants are based at their home. Participants will receive exercises (attached in the study protocol document) with real time instructions from the physiotherapist. Instructions on downloading and accessing Zoom platform will be given to the participants in the first in-person session to ensure their readiness to access the Zoom platform. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in the pain intensity measured by Numeric pain rating scale | The Numeric pain rating scale assesses the pain intensity using 11 points scale, where 0 indicates no pain and 10 indicates the worst pain | Baseline and after 8 weeks of the intervention |
| Change in physical function measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) | The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), a validated self reported questionnaire designed to assess the physical function of individuals with knee osteoarthritis. it consists of 17 items rated on a 5-points Likert scale ( 0=none, 4=extreme). Scores range from 0 to 68, in which higher scores indicate worse physical function | Baseline and after 8 weeks of the intervention |
| Changes in lower limb strength measured by 30 seconds chair stand test | The 30 seconds chair stand test assesses the lower limb strength and functional performance. The participant will be asked to stand straight and return to sitting on a standard high chair as many times as possible within 30 seconds without using their arms. The total number of completed full stand will be recorded and a higher number indicates better lower limb strength and function. | Baseline and after 8 weeks of the intervention |
| Measure | Description | Time Frame |
|---|---|---|
| Exercise adherence measured by weekly adherence log | The weekly adherence log will be completed by the physical therapist to assess the participants adherence to either in person or zoom sessions. Adherence will be calculated as the number of calculated sessions over 8 weeks (2 sessions per week, 16 sessions). A higher number indicates better adherence to the exercise program. | Weekly during 8 weeks of the intervention and at the end of the 8 weeks |

| Usability and satisfaction of Zoom based tele-rehabilitation measured by Tele-health Usability Questionnaire. | The Telehealth Usability Questionnaire (TUQ) is a validated patient-reported questionnaire to evaluate the usability of tele health services across six domains: usefulness, ease of use, interface quality, interaction quality, reliability, and satisfaction. It includes 21 items rated on a 5-point Likert scale (1 = strongly disagree to 5 = strongly agree). The higher scores indicate greater usability and satisfaction with Zoom tele-rehabilitation | After 8 weeks of the intervention |
