Intervention
EVENTS
Participants randomized to the FitMi group were given a FitMi system with a
custom 10″ touchscreen tablet. They received 30 minutes of training on how to
set up and use the FitMi system. They were instructed to spend most of their
time performing UE exercises, but access to the trunk and leg exercises in the
FitMi software was not disabled. Participants randomized to the conventional
therapy group were given a booklet of paper exercises that were selected from
the same library of 40 exercises available in the FitMi software. The booklet
was placed in a sensorized folder which included an accelerometer to detect
movement events and a magnetometer and magnet on opposite sleeves to detect when
the folder was opened or closed. These events were recorded to a memory card by
an embedded microcontroller.For both groups, a supervising rehabilitation therapist selected the exercises
for each participant based on their specific impairments. All participants
received 30 minutes of training from the therapist on how to perform the
selected exercises correctly. After the 3-week exercise period, participants
returned for an end-of-therapy assessment. At this assessment, participants
returned the FitMi system or the sensorized booklet of exercises for data
collection. Participants returned 1 month later for a follow-up assessment.
