A total of 454 hospitalized older adults were randomised to the experimental (HIFE) group or the control group. The control group received 5 regular individual physiotherapy sessions a week. In the HIFE group, 3 of these sessions were subsituted by group-based HIFE sessions, where a maximum of 6 participants performed weight-bearing functional exercises targeted at varying levels of mobility with a physiotherapist for 45-60 minutes. Results show that there were no significant differences in improvement of functional outcomes between group. No adverse events were related to participation in the trial. However, with the group treatments, physiotherapists were able to work significantly more efficient.
