Abstract
Background. Postural stability after anterior circulation stroke is considered a major cause of falling and functional dependence. Recently, special attention regarding mechanisms about standing balance recovery following stroke has been grown. Evidence supports the effectiveness of vestibular rehabilitation therapy for patients with central vestibular disorders. Objective. A randomized controlled trial was designed to investigate the effects of vestibular rehabilitation on postural stability in anterior circulation stroke patients. Methods. Thirty-six patients (27 males, 9 females) their age range from (44 to 72 years) diagnosed with anterior circulation stroke were enrolled and assigned randomly into two similar groups: experimental group (A) received vestibular rehabilitation therapy in addition to conventional treatment 3 sessions per week for six consecutive weeks, but the conventional group received only conventional treatment. All patients were assessed for postural stability using sensory organization test and berg balance scale and for gait performance using time up and go test at baseline and after 6 weeks at end of the rehabilitation process. Results. Statistical analyses using mixed design MANOVA showed that there was statistical significant difference (p < 0.05) in all outcome variables for both groups in favor to VR group especially in SOT5, SOT6 while there were non-significant differences between groups in SOT1 variable. Conclusion. Vestibular rehabilitation may be a promising approach if it is integrated as standard in the rehabilitation program for improving postural control after anterior circulation stroke affecting parieto insular region.
