Objective:
To explore what it means for patients with knee osteoarthritis (OA) to engage in online delivered exercise and education.
Method:
We combined participant observations and focus group interviews with knee OA patients who engaged in an 8-week program (12 exercise sessions and 2 education sessions) delivered online. Data underwent a three-level phenomenological-hermeneutic interpretation inspired by Ricoeur's narrative and interpretation theory.
Results:
We performed 17 participant observations during online group-based exercise sessions with twenty individuals with knee OA (12 females), median age 71 years (range: 48 to 81), and five focus group interviews with fifteen of the individuals. The following three themes emerged from the data analysis: 1. Exercise engagement portrays an experience of ownership of the exercise-based treatment, leading to better function and well-being and raising hope for the future 2. A good start but only halfway supported portrays perceived well-guided in performing knee OA exercise, however also some unmet support needs in the online format, and 3. Beneficial peer companionship with online constraints portrays a socially engaging peer forum that, at times, was limited by the online format.
Conclusions:
This phenomenological-hermeneutic study reflects that supervised online exercise and education facilitate identity mobility, potentially increasing self-efficacy to adopt weekly exercise habits in patients with knee OA. However, the program may benefit from enabling a more interactive approach between peer participants and combining the online format with physical group classes. Moreover, further individualization and focus on a gradual approach toward self-management are encouraged.
