The impact of an high intensive exercise program on gait after stroke: a randomized controlled trial
(English)Manuscript (preprint) (Other academic)
Stroke often results in asymmetric gait with disturbed balance, which may increase the risk of accidental falls.
The purpose of this study was to evaluate the impact of a high intensive exercise program after stroke on gait. 34 post-stroke individuals with risk of falls were included in the five week randomized controlled trial. The participants were assessed, included and randomized to the intervention group (IG) or control group (CG) at 3 to 6 months after stroke onset. The IG received a high intensive strength and balance exercise program along with a weekly educational group discussion on fall risk and security aspects, whereas the CG received weekly group discussions on hidden dysfunctions after stroke. Assessments were made before, post-intervention and at 3-months follow-up. Statistically significant (p<0.05) improvements were seen in the IG vs. the CG at post intervention compared with baseline in double support time for the non-paretic leg (DSTnp), variability (measured as coefficient of variation, CV) in Step Time for the paretic leg (STCVp) and the non-paretic leg (STCVnp), and in variability in Cycle Time for the paretic (CTCVp) and non-paretic leg (CTCVnp); at 3-months follow-up compared with baseline in DSTnp, STCVp, CTCVp and CTCVnp, and DSTCVp. At 3-months follow-up, the decrease in the STCVnp and the variability in Step Length of the non-paretic leg (SLCVnp) were more pronounced in the CG than in the IG.
The findings suggest that high intensive exercise programs have a positive effect on gait, and can be useful in diminishing gait asymmetry as a fall-risk factor in people after stroke.
