Objective
To
investigate the STRoke Interactive Virtual thErapy (STRIVE)
intervention on upper-extremity clinical outcomes in community-dwelling
stroke survivors.
Design
Assessor-blinded randomized controlled trial.
Setting
Study
screening and testing was conducted in a university clinic.
Participants completed the virtual therapy (VT) intervention in a
community-based stroke support group setting.
Participants
Of
124 stroke survivors initially assessed, 60 participants were recruited
(time poststroke, 13.4±8.9 y). Participants were allocated to either VT
or control group using a block randomization design and were stratified
by sex.
Interventions
Participants
were randomized to receive 8 weeks of VT or usual care. The
intervention consisted of approximately 45 minutes of twice weekly VT
training on the Jintronix Rehabilitation System.
Main Outcome Measures
Between-group
differences in the Fugl-Meyer Upper Extremity scale and Action Research
Arm Test score were joint primary outcomes in this study.
Results
Significant between-group differences for the Fugl-Meyer Upper Extremity scale were seen at the end of the intervention (F1, 1=5.37, P=.02, d=0.41). No significant differences were observed with the Action Research Arm Test. No adverse events were reported.
Conclusions
We
demonstrated clinically meaningful improvements in gross upper
extremity motor function and use of the affected arm after a VT
intervention delivered via a community-based stroke support group
setting. This data adds to the contexts in which VT can be used to
improve upper limb function. Use of VT in community-based rehabilitation
in chronic stroke recovery is supported.
