Purpose
The
objective of the study was to evaluate the methodological quality of
motor intervention randomized controlled trials (RCTs) published in the
stroke rehabilitation literature and to examine trends in quality over
time.
Methods
A systematic literature
search was conducted for all English articles (published up to December
2013) examining rehabilitation for motor recovery poststroke. All RCTs
with a human sample, of which at least 50% had a stroke, were included
in the analysis. A Physiotherapy Evidence Database (PEDro) score was
assigned to assess methodological quality. A one-way analysis of
variance was conducted to examine adherence to quality items overall and
over time, with post hoc t-tests performed where appropriate.
Results
Six
hundred seventy-six RCTs met inclusion criteria, of which 32.0% had
excellent, 42.0% good, 23.1% fair, and 3.0% poor methodological
qualities. The overall mean PEDro score was 6.6 ± 1.6; with scores
improving significantly between 1979-1983 and 2009-2013 (5.0 ± 1.4
versus 7.0 ± 1.5; P = .0003); however, no significant improvements in individual items were found (P > .05).
Conclusions
This
study showed improvements in the total methodological quality of motor
intervention RCTs in stroke rehabilitation over time.??? However, no
relationship was found between individual quality items and improvement
over time.
