Recruiting

• Conditions: Knee Osteoarthritis

• Registration Number: NCT06956222
• Lead Sponsor: King Abdulaziz University

Brief Summary

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 :

* Does combining in-person and video sessions improve pain and physical function in people with knee osteoarthritis?

* Does combining in-person and video sessions improve adherence to the exercise program?

* Are people satisfied with video sessions using Zoom?

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 :

* Attend either (one in-person and one video session per week) or (two in-person sessions per week) for 8 weeks.

* Perform exercise program that suits their needs during in-person and video sessions.

* Record the number of attended sessions over 8 weeks.

* Complete questionnaires about pain, physical function at the start and the end of the study.

* Complete questionnaire about usability and satisfaction at the end of the study.

Primary Outcome Measures

Name	Time	Method
Change in the pain intensity measured by Numeric pain rating scale	Baseline and after 8 weeks of the intervention	The Numeric pain rating scale assesses the pain intensity using 11 points scale, where 0 indicates no pain and 10 indicates the worst pain
Change in physical function measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)	Baseline and after 8 weeks of the intervention	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
Changes in lower limb strength measured by 30 seconds chair stand test	Baseline and after 8 weeks of the intervention	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.

Secondary Outcome Measures

Name	Time	Method
Exercise adherence measured by weekly adherence log	Weekly during 8 weeks of the intervention and at the end of the 8 weeks	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.
Usability and satisfaction of Zoom based tele-rehabilitation measured by Tele-health Usability Questionnaire.	After 8 weeks of the intervention	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
