Conditions

People with hip and/ or knee OA diagnosed by a physician or self-reported OA. Self-reported OA should meet the criteria of idiopathic OA of the hip (Altman et al., 1991) or OA of the knee (Altman et al., 1986). M15 M16 M17

Interventions

Group 1: The overall aim of Join2Move is to promote a physically active lifestyle. The Join2Move intervention runs for twelve weeks and consists of an application that focuses on behavioural increased
the videos focus on e.g. the aetiology of OA, pain management, weight management, motivation, medications and social influences on pain. The information can also be read (in text form). Automated mess

Inclusion criteria

Inclusion criteria: - Age: people with hip OA aged > 50 years and people with knee OA aged > 38 years according to the American College of Rheumatology (ACR) (Altman et al., 1991; Altman et al., 1986). - OA diagnosed by a physician or self-reported OA in the hip and/or the knee (to verify the self-reported diagnosis, clinical tests are performed to assess the presence of hip and/or knee OA according to the ACR) (Altman et al., 1991; Altman et al., 1986). - People who did not receive physical therapy and/or treatments other than from a general practitioner (GP) for OA in the last six month

Exclusion criteria

Exclusion criteria: - People without an internet access at home - People without having a smartphone or tablet - People who are unable to understand the German language - People who have contraindications (loss of consciousness and cardiovascular disease) for physical activity without medical supervision. In case of uncertainty regarding the suitability for physical activities, a medical clarification is requested. - People who are on a waiting list for the implantation of a total endoprosthesis (TEP), who already have a fixed appointment for this or whose affected joint has already been replaced by a TEP.

Design outcomes

Primary

MeasureTime frame
To investigate usability of Join2Move, the following primary outcome measures will be used: - Usability/user satisfaction (System Usability Scale (SUS) (P. W. Jordan, Thomas, McClelland, & Weerdmeester, 1996), To examine the preliminary effectiveness of Join2Move, the following primary outcome measures will be used: - Hip Osteoarthritis Outcome Score (HOOS) questionnaires (Blasimann, Dauphinee, & Staal, 2014) and Knee Injury and Osteoarthritis Outcome Score" (KOOS) (Kessler, Lang, Puhl, & Stove, 2003). - Physical functioning (subscale "Function of Daily Living" of the HOOS or the KOOS.

Secondary

MeasureTime frame
To examine the usability of Join2Move, the following secondary outcome measures will be used: - Program usage (quantitative data on app usage). - Thinking Aloud method (Charters, 2003; Nielsen, 1993, 2000). In the Thinking-Aloud method, participants receive specific tasks to perform in the app. While the participant is performing these tasks, their thoughts should be spoken aloud. This allows the examination of the usability of the app. The time until the completion of the tasks is stopped and the spoken thoughts are recorded (audio recordings). The Thinking Aloud method is not conducted with all participants. Five participants will be randomly selected. To examine the preliminary effectiveness of Join2Move, the following secondary outcome measures will be used: - Physical activity (International Physical Activity Questionnaire (IPAQ) (Lee, Macfarlane, Lam, & Stewart, 2011; Wendel-Vos, Schuit, Saris, & Kromhout, 2003). - Self-perceived effect (single question about the extent of change in OA-related symptoms. A score ranges from 1 (=much better) till 6 (=much worse)). - Pain and fatigue (Numeric rating scale (11-point Likert scale) and subscales of the HOOS and KOOS, respectively). - Self-management (Patient activation measure (PAM-13) (Zill et al., 2013).
