Table 2.

Some of the questions addressed through the process evaluation that could explain the barriers and facilitators to the future roll-out of supported home exercise programmes for the management of musculoskeletal problems, based on the Maintenance and Adoption aspects of the RE-AIM framework

Patients	Are people with common musculoskeletal conditions willing to receive a supported home exercise programme via an App, outside of a trial setting, and why? Was the intervention perceived to be more convenient for the Supported Home Exercise Group? Why was that? What were the costs associated with receiving treatment to the patients of the Supported Home Exercise Group and Face-to-Face Physiotherapy Group? Would patients recommend the intervention to others, and why?
Physiotherapists	Did physiotherapists feel that the intervention was effective? If not, why not? Would physiotherapists recommend this intervention beyond the trial setting, and why or why not? What will be the reasons that physiotherapists are willing to adopt the intervention, and use all features of the App (and website) as part of mainstream treatment outside of a trial setting? What were the reported problems with providing the intervention?
Stakeholders: health services managers and policy makers	Do the stakeholders believe this intervention is scalable, and why is that? Are stakeholders willing to adopt this model of care as part of their service delivery? Are stakeholders willing to invest in scaling up this intervention? Would stakeholders advocate for this intervention?
Health systems	Do public hospitals have the resources to deliver a supported home exercise programme? Can this intervention be incorporated into mainstream treatment? Are the results generalisable to other patients, public or private hospitals, the private sector or other countries?
