Feasibility and short-term effects of Activity Coach+: a physical activity intervention in hard-to-reach people with a physical disability

Purpose: Existing physical activity interventions do not reach a considerable proportion of physically disabled people. This study assessed feasibility and short-term effects of Activity Coach+, a community-based intervention especially targeting this hard-to-reach population. Methods: Feasibility was determined by reach, dropouts, and compliance with the protocol. Physical activity was measured with the Activ8 accelerometer and the adapted SQUASH questionnaire. Health outcomes were assessed by body composition, blood pressure, hand grip force, 10-metre walk test, 6-minute walk test, and the Berg Balance Scale. The RAND-36, Exercise Self-Efficacy Scale, Fatigue Severity Scale, and IMPACT-S were administered. Measurements were performed at baseline and after 2 and 4 months. Changes over time were analysed by Friedman tests. Results: Twenty-nine participants enrolled during the first 4 months, of whom two dropped out. Intervention components were employed in 86-100% of the participants. Physical activity did not change after the implementation of Activity Coach+. Body mass index (p = 0.006), diastolic blood pressure (p = 0.032), walking ability (p = 0.002), exercise capacity (p = 0.013), balance (p = 0.014), and vitality (p = 0.049) changed over time. Conclusions: Activity Coach + is feasible in a community setting. Indications for effectivity of Activity Coach + in hard-to-reach people with a physical disability were found.
