Abstract
Objective
To
investigate effects of a 12-week movement-to-music (M2M) intervention
on physical and psychosocial outcomes in people poststroke.
Design
Two-arm randomized controlled trial.
Setting
A community-based fitness facility.
Participants
Participants (N=47) with stroke between 18 and 65 years old were randomized to M2M (n=23) or waitlist control (n=24).
Interventions
Participants
in M2M completed three 60-minute exercise sessions per week for 12
weeks. Controls received biweekly educational newsletters via mail.
Main Outcome Measures
Primary outcomes included Six-Minute Walk Test (6MWT, in meters), Five Times Sit-to-Stand Test (FTSST, in seconds) and Timed Up and Go (TUG, in seconds). Secondary outcomes were self-reported measures using PROMIS Fatigue and Pain Interference Short Form 8a.
Outcomes were collected at baseline and post-intervention. Analyses
involved descriptive statistics and adjusted linear mixed models.
Results
Mixed
models adjusted for the respective baseline values and demographic
variables showed that M2M participants had longer 6MWT distance (LSM
difference [95% CI]=14.5 [-12.9, 42.0]), more FTSST time (2.0 [-4.5,
8.5]), and less fatigue (-3.0 [-7.2, 1.2]) compared to control
post-intervention. When controlling for baseline TUG and demographic
variables, there were larger increase in 6MWT distance (37.9 [-22.7,
98.6]), lower FTSST time (-6.1 [-18.5, 6.2]), and decrease in fatigue
(-6.5 [-13.1, 0.2]) in M2M compared to controls. Moderate effect sizes
were observed for improving 6MWT (d=0.6), FTSST (d=-0.6), and fatigue (d=-0.6). There was no group difference in change in TUG time and pain interference, with trivial effect sizes (d=-0.1).
Conclusion
Movement-to-music
may be a valuable exercise form for adults with stroke. Future studies
are needed to determine optimal exercise doses for improving health and
function in this population.
