Effect of Clinic-Based and Asynchronous Video-Based Exercise on Clinic and psychosocial Outcomes In Patients with Knee osteoarthritis
ABSTRACT
Background:
Limited studies have explored the potential of video-based telerehabilitation for knee Osteoarthritis (OA) patients.
Objective:
This study examined the effect of a Clinic-based Strengthening Exercise (CbSE) and Asynchronous Video-based Strengthening Exercise (AVbSE) among patients with knee OA.
Methods:
Fifty-two consenting patients participated in this 8-week experimental study; they were assigned to either CbSE or AVbSE group. CbSE is a circuit exercise module comprising knee flexion and extension warm-up in sitting (3-5 repetitions), quadriceps isometric setting; quadriceps strengthening exercise; hamstring clenches; wall squat and a cooldown of knee flexion and extension. The AVbSE is an asynchronous video-based version of CbSE.
Results:
Both CbSE and AVbSE produced significant effects in all the outcomes (p<0.05) across baseline, 4th and 8th week of the study except in muscle strength, social support, social activities domains of OAKHQoL and the Activity limitation and Performance Restriction domain of IKHOAM where no main effect of time was observed. There was a significant difference in all OAKHQoL measure domains except social activities (17.6(1.2) vs 22.8(1.2); p=0.003) and average pain (2.8(1.6) vs 2.3(1.6); p=0.032) with higher AvbSE mean scores. However, a higher score was observed for the CbSE group in the QVAS least pain domain (1.2(0.2) vs 0.7(0.2); p=0.039). Also, interaction effects showed that AvbSE scores were significantly higher for OAKHQoL physical activity and mental health domains at all time points. However, CbSE was higher for the Physical performance domain of IKHOAM at the 8th week.
Conclusions:
Clinic-based strengthening exercise circuit training and its asynchronous video-based variant effectively reduce pain, impairments and disability and increase patients' quality of life. While AVbSE was associated with higher improvement in most HRQoL domains, CbSE led to higher improvement in average pain.
