Objective:
Evaluate the impact of self-reported sleep problems on post-stroke recovery.
Design:
Cross-sectional
secondary analysis of longitudinal data from the Locomotor Experience
Applied Post-Stroke (LEAPS) rehabilitation and recovery study (phase-III
single-blind randomized controlled clinical trial). Group medians were
compared for three sleep problem groups across three time points.
Setting:
Outpatient and in-home physical therapy.
Subjects:
Adults during the first year following stroke (
n = 408, 380, 360 at 2, 6, 12 months, respectively).
Interventions:
The
original study compared effects of locomotor training with body weight
support in the year post-stroke. This analysis evaluated function in
three sleep/functional-impact groups: no sleep problems, sleep problems
with no-to-minimal-impact and sleep problems with
moderate-to-quite-a-bit of impact.
Main measures:
Participants’
responses regarding if they had “a sleep problem, such as insomnia”
and, if so, what the impact was on their function. Stroke Impact Scale
subscales for strength, hand function, mobility, ADLs, memory,
communication, emotion, participation, and percent recovery.
Results:
About
25% (30% elsewhere)of people with stroke reported sleep difficulty, 10% perceived
sleep problems negatively impact function. Groups self-reporting worse
sleep performed worse in all functional subscales (except self-perceived
percent recovery) during the first year post-stroke.
Conclusion:
Self-reported poor sleep adversely effects post-stroke functional recovery.
