Abstract

Enhance®Fitness (EF) is an evidence-based exercise program recommended for management of osteoarthritis (OA). However, access to EF is limited in rural areas. Accordingly, we evaluated the feasibility and acceptability of remotely delivered EF in rural, community-dwelling older adults with symptomatic knee OA. A single arm pilot trial of remotely delivered EF classes was conducted. Videoconferencing was used to livestream the instructor-led, 1-hour EF classes 3 days/week for 12 weeks. Outcomes were assessed at baseline and immediately post-intervention. A total of 15 participants were enrolled with a median age of 70 years (interquartile range [IQR]: 67-75) and 14 (93%) were women. Median EF class attendance rate was 91% (IQR: 85-94%). Knee pain, as measured by the Knee injury and Osteoarthritis Outcome Score (KOOS), improved significantly from baseline to 12-week endpoint (mean difference=-11.4 [95% CI:-20.9, -2.0); P=0.02). In addition, participants’ self-reported knee function improved significantly (mean difference in KOOS Function score=-11.8 [95% CI:-18.4, -5.2]; P<0.01) as well as their physical capacity (mean difference in Timed Up and Go test time=1.8 seconds [95% CI: 0.2, 3.4]; P=0.03). All participants (100%) were very satisfied with remotely delivered EF classes and there were no serious adverse events. Findings from this pilot trial indicate that remotely delivered EF is feasible and acceptable in rural older adults with knee OA.
