To describe device use and physiotherapy support in the post-hospital phase of the AMOUNT rehabilitation trial. We performed an evaluation of the support required for device use by participants randomised to the intervention group who received digitally-enabled rehabilitation in the post-hospital phase (n = 144). Intervention, additional to standard rehabilitation, utilised eight digital devices (virtual reality videogames, activity monitors and handheld computer devices) to improve mobility and increase physical activity. Participants were taught to use devices during inpatient rehabilitation and were then discharged home to use the devices for the remainder of the 6-month trial. Physiotherapist-participant contact occurred every 1–2 weeks using a health coaching approach, including technology support when required. Intervention datasheets were audited, and descriptive statistics used to report device use and support required. Participants (mean (SD) age 70 (18) years; 49% neurological health conditions) used an average of 2 (SD 1) devices (98% used an activity monitor). Eight percent of physiotherapy contact included technology support with 30% provided remotely. Support addressed 845 issues categorised under initial set-up and instruction (27%), education and training (31%), maintenance (23%) and trouble-shooting (19%). Digital devices can be used for home-based rehabilitation, but ongoing technology support is essential.
