Toward Optimizing Home Rehabilitation Technology
As reviewed in An important question is whether the system was usable by more severely impaired
individuals, as there are fewer options available for such persons for
continuing movement practice. The lower half of participants with more severe
impairments (UEFM <40) still achieved on average 4427 repetitions, an amount
that exceeded the theoretical target dose of 2700 repetitions. Notably, most
participants were able to exceed the 2700-repetition target in a shorter amount
of time than was prescribed, because they achieved an average rate of exercise
of 41 ± 17 reps/minutes, which was greater than the 5 reps/minute we estimated a
priori. This indicates that FitMi was accessible and motivating for individuals
with a range of impairment levels, which is a key requirement for optimizing
home rehabilitation technology as it allows a single solution to be used across
a broad population.As shown in While home training with FitMi led to a significantly greater reduction in UE
impairment than paper-based exercise, an important question is whether the
amount of improvement was clinically significant. The Minimal Clinically
Important Difference (MCID) for the UEFM has been reported to be 4 points for
subacute patients,
