Objective: This study aimed to the effects of eccentric contraction training and concentric contraction training among ankle joint exercises on the balance of stroke patients and to compare their effects.
Method: Forty patients with hemiplegia resulting from stroke were randomly and equally assigned to either an eccentric contraction training group or a concentric contraction training group. Using the Korean version of the Berg Balance Scale (K-BBS), the Timed Up and Go test with the addition of a cognitive task (TUGcongnitive), the Functional Forward Reach Test (FRT), and BioRescue as measurement tools, changes in the weight-bearing ratios of the paretic and non-paretic sides (Footsprints) were measured, as well as the total movement area of the central point of the body with the eyes open and closed. Changes according to the time in each measurement item and differences between the groups were analyzed with repeated measures analysis of variance (ANOVA). The statistical significance level was set at p<.05.
Results: In comparison between the times for each group, K-BBS, TUGcognitive, FRT, and BioRescue, Footsprints, SEO and SEC improved in both groups with the passage of time. All variables improved to a greater cxtent in the eccentric contraction training group than in the concentric contraction training group.
Conclusion: Eccentric contraction training, which is ordinarily accessible, involves low risk and is economical. Thus, it may be provided as an effective treatment method aimed at enhancing the balance ability of stroke patients whose onset period is shorter than two years.
