Abstract
Objective
To examine the effects of bilateral robotic priming combined with mirror therapy (R-mirr)
versus bilateral robotic priming combined with bilateral arm training (R-bilat), relative
to the control approach of bilateral robotic priming combined with movement-oriented
training (R-mov) in patients with stroke.
Design
A single-blind, preliminary, randomized controlled trial.
Setting
Four outpatient rehabilitation settings.
Participants
Outpatients with stroke and mild to moderate motor impairment (N = 63).
Interventions
Patients received 6 weeks of clinic-based R-mirr, R-bilat, or R-mov for 90 minutes/day,
3 days/week, plus a transfer package at home for 5 days/week.
Main Outcome Measures
Fugl-Meyer Assessment upper extremity subscale (FMA-UE), ABILHAND, and Stroke Impact
Scale (SIS) version 3.0 scores before, immediately after, and 3 months after treatment
as well as the lateral pinch strength and the accelerometry before and immediately
after treatment.
Results
The posttest results favored R-mirr over R-bilat and R-mov on the FMA-UE score (P<.05). Follow-up analysis revealed that significant improvement in FMA-UE score was
retained at the 3-month follow-up in the R-mirr over R-bilat or R-mov (P<.05). Significant improvements were not observed in the R-mirr over R-bilat and R-mov
on other outcomes.
Conclusions
Between-groups differences were only detected for the primary outcome – FMA-UE. That
was R-mirr was more effective at enhancing upper-limb motor improvement, and the effect
has the potential to be maintained at 3 months of follow-up.
