Abstract
Background. In the past several years,
several randomized controlled trials (RCTs) have been reported regarding
the efficacy of treadmill-based
walking-specific rehabilitation programs, either
individually (TT) or combined with body weight support (BWSTT), over
control
group therapies poststroke. No clear consensus
exists as to whether treadmill-based interventions are superior in
rehabilitating
walking speed (WS) poststroke. Objective. To review published RCTs examining TT and BWSTT poststroke and describe the effects on improving and retaining WS. Methods.
A systematic literature search in computerized databases was conducted
to identify RCTs whose methodological quality was
assessed with PEDro. Pre- and post-WS, change in
WS, functional outcomes, and follow-up speed were extracted and
calculated
from each study. Additionally, statistical results
of each study were examined, and the intragroup and intergroup effect
sizes
(ESintra and ESinter, respectively) were calculated. Results.
All studies (8 TT; 7 BWSTT) met the inclusion criteria, and their
methodological quality was generally good, with a mean
PEDro score 6.9/10. Of the 15 studies, 8 studies (4
TT; 4 BWSTT) reported intragroup significant increases of WS, whereas
only 4 (4 TT) found superiority of treadmill
interventions. Nine studies demonstrated large ESintra (4 TT; 5 BWSTT), yet only 3 showed large ESinter (1 TT; 2 BWSTT). Four studies (2 TT and 2 BWSTT) reported retention of gains in WS, regardless of intervention. Conclusions. Treadmill-based interventions poststroke may increase and retain WS, but their universal superiority to other control group
therapies has failed to be established.
