Abstract
To examine the effects of an Arabic smartphone application on adherence to home exercise programs (HEPs) and the effectiveness of mobile-based HEPs on pain, physical function, and lower-limb muscle strength among older women with knee osteoarthritis (OA).
This randomised control trial (ClinicalTrials.gov: (NCT04159883) enrolled 40 women aged ≥50 years with knee OA who were randomised into the app group (experimental; n = 20) receiving HEPs using an Arabic smartphone application called "My Dear Knee", whereas the paper group (control; n = 20) receiving HEPs as hand-outs. Both groups had the same exercise program. Outcome measures were self-reported adherence, changes in the Arabic Numeric Pain Rating Scale, the Arabic version of the reduced Western Ontario, McMaster Universities Osteoarthritis Index-Physical Function subscale, and Five-Times Sit-To-Stand Test scores. All participants were assessed at baseline, at week 3 and week 6. Using completer-only analyses, the repeated measures ANOVA was used to compare the means of the outcome measures between the two groups.
At the end of week 6, the app group reported greater adherence to HEPs (p = .002) and significant reduction in pain (p = .015).
A smartphone application with motivational and attractive features could enhance adherence to HEPs in this patient cohort.
IMPLICATIONS FOR REHABILITATION
Older adults with knee OA may face many obstacles that prevent or limit their adherence to the prescribed HEP.
Smart device apps supported with attractive and motivational features could be an effective strategy to enhance adherence to HEPs among older adults with knee OA.
Using such remote technology appears to overcome the barriers that may limit the ability of older women to receive supervised physical therapy in a clinical setting.
