The Effect of Ankle Joint Muscle Strengthening Training and Static Muscle Stretching Training on Stroke Patients' Plantar Pressure and Gait

Abstract

[Purpose] This study implement ankle joint dorsiflexion training for ankle muscle the weakness that impairs stroke patients' gait performance, to examine the effect of the training on stroke patients' plantar pressure and gait ability. [Subjects and Methods] In this study, 36 stroke patients diagnosed with stroke due to cerebral infarction or cerebral hemorrhage performed the training. Static muscle stretching was performed four times a week for 20 minutes at a time for 6 weeks by the training group. Ankle dorsiflexor training was performed four times a week, two sets per time in the case of females and three sets per time in the case of males for 6 weeks, by another group. Center of pressure sway amplitude was measured using the F-scan system during gait. All subjects were assessed with the same measurements at a pre-study examination and reassessed at eight weeks. Data were analyzed statistically using the paired t-test and one-way ANOVA. [Results] Among the between ankle dorsiflexor training group, static muscle stretching group, and control group, the difference before and after the training were proven to be statistically significant. [Conclusion] Compared to other training groups, the ankle muscle strength training group showed statistically significant increases of forward thrust at stroke patients' toe-off which positively affected stroke patients' ability to perform gait.
