Abstract
Background.
Trunk function is important for standing balance, mobility, and
functional outcome after stroke, but few studies have evaluated the
effects of exercises aimed at improving core stability in stroke
patients.
Objective. To investigate the effectiveness of core
stability training on trunk function, standing balance, and mobility in
stroke patients.
Methods. An assessor-blinded, randomized
controlled trial was undertaken in a stroke rehabilitation ward, with 32
participants randomly assigned to an experimental group or a control
group (n = 16 each). The experimental group received 400 minutes of core
stability training in place of conventional programs within total
training time, while the control group received only conventional
programs. Primary outcome measures were evaluated using the Trunk
Impairment Scale (TIS), which reflects trunk function. Secondary outcome
measures were evaluated by pelvic tilt active range of motion in the
sagittal plane, the Balance Evaluation Systems Test–brief version
(Brief-BESTest), Functional Reach test, Timed Up-and-Go test (TUG), and
Functional Ambulation Categories (FAC). A general linear
repeated-measures model was used to analyze the results.
Results. A treatment effect was found for the experimental group on the dynamic balance subscale and total score of the TIS (P = .002 and P < .001, respectively), pelvic tilt active range of motion (P < .001), Brief-BESTest (P < .001), TUG (P = .008), and FAC (P = .022).
Conclusions.
Core stability training has beneficial effects on trunk function,
standing balance, and mobility in stroke patients. Our findings might
provide support for introducing core stability training in stroke
rehabilitation.
