During the preliminary phase of the study, participants (SCI clinicians and patients with SCI) reported favourable usage of the self-management app and unanimously agreed it would benefit people with SCI. With the ubiquity of portable electronic devices, an opportunity exists to help participants and informal caregivers navigate the journey from rehabilitation to integration back into the community. The research team will use both quantitative and qualitative methods involving a rater-blinded, randomized controlled trial with a stepped wedge design and semi-structured interviews. The participant-specific intervention will involve the use of the self-management app focusing on the self-management of SCI accompanied by five to six in-person or telephone/Skype contacts that will occur over a three-month period.
