Donning times during sessions. a Donning times for all caregivers (donning for SCI user sessions) (blue) for sessions 1 (N = 8), the last training session labelled 4 here (N = 7), however for 3 user pairs the 5th session was the last training, 10th (N = 3) and 14th (N = 2) sessions showing therefore donning times approximately every 4–5 sessions. Donning times achieved by OTs (green) (N = 3) show first and last OT training sessions with researchers. The box for OT’s at last training is hardly visible because there was little variability in the values. b Mental demand (min 0, max 20) experienced by caregivers (measured by NASA TLX [34]) at each particular session and the corresponding donning time during that session
