New technologies may provide an affordable way to increase the dose of practice for people undertaking rehabilitation. Study aims: (1) Which technologies were used to address participants’ mobility limitations during the inpatient phase of the AMOUNT rehabilitation trial? (2) Did participants perceive technologies to be enjoyable and easy to use, and which factors influenced this?

Design: process evaluation from a randomised controlled trial in which 149 participants [52% male; mean age 70 (SD18); 54% neurological conditions] were allocated to the intervention group.

Intervention: tailored technology prescription according to a protocol matching exercises from eight technologies (commercially-available: Nintendo Wii; Xbox Kinect; activity monitors; smartphone apps; rehabilitation-specific Humac; Fysiogaming; Stepping Tiles; exercise iPad apps) to seven mobility limitations.

Outcome measures: intervention dose, technologies used, mobility limitations addressed, Physical Activity Enjoyment (PACES; 18–126) and System Usability Scales (SUS; 0–100).

Participants received on average 11 (SD11) sessions of 43 (SD11) minutes duration. Each participant used on average 4 (SD1) technologies to address a mean of 4 (SD1) different mobility limitations. Intervention focused largely on limitations related to standing (80%) and stepping (79%), as well as on physical activity levels (90%). The Humac was the most frequent first-introduced technology (35% of participants). Activity monitors (80%) and iPad apps (71%) were most prescribed, and commercially-available exergames and smartphone apps used least. At 3 weeks, participants perceived technology use as enjoyable [mean PACES 95.4 (SD23.2)] and rated usability above average [mean SUS 72.2 (SD18.8)]. Enjoyment and usability were positively related to previous technology use (P<0.01) and younger age (P≤0.03). Usability was greater in those with neurological conditions (P<0.05). Previous technology use remained associated with usability after adjustment for other factors (P=0.003).

In inpatient rehabilitation, tailored prescription of technologies can address a range of mobility limitations and was well accepted. Previous technology use enhances uptake.
