Setting and subjects
RECRUITMENT
Focus groups (n = 4), one at each intervention site, were conducted with a convenience sample of participating physiotherapists, occupational therapists and therapy assistants. They took place at the end of the trial, when therapists had between 3 and 15 months experience of using the intervention. Due to the COVID-19 pandemic, the time period between the recruitment phase of the cluster trial, and focus group data collection, ranged between 1–12 months.Semi-structured interviews were conducted with a convenience sample of patient participants. Interviews took place within 7 days of completion of trial interventions; ensuring participants had recent experience of rehabilitation to draw on.Ethical approval was obtained from South Central–Berkshire B Research Ethics Committee (Ref: 18/SC/0582)
