Abstract
Cerebrovascular accident (Stroke) incidence is rapidly increasing and is considered to be one of the leading causes of death and physical impairment on a global level. These impairments aren’t limited to motor weakness but can also include impairments in somatosensory functions essential for producing accurate and specific motor actions.
Aim of the study: To determine the efficacy of lower limb sensory training on postural stability in stroke patients.
Procedures: Thirty male ambulant patients with ischemic stroke in the distribution of anterior circulation with a modified Ashworth scale not exceeding 1+. The ages of the patients were between 50-65 years. They were recruited three to six months from the onset of their symptoms. Then, they were assigned randomly into two equal groups, study group (A) and control group (B). The patients in study group (A) have been given a combination of a sensory-based intervention program for the affected lower limb and a carefully selected physical therapy program. Control group (B) patients were treated with the same selected physical therapy program. The treatment was executed in three sessions per week for six weeks. Each session was done in a 90 minutes window. Postural stability was evaluated with the Berg Balance Scale (BBS) and the Biodex balance system which measured the three stability indices (mediolateral stability index [MLSI]), anteroposterior stability index [APSI], and overall stability index [OASI]) in both eyes-open and eyes-closed circumstances before and after interventions.
Results: A significant DROP was noted in the indices of the Biodex balance system with eyes opened and eyes closed of both group A and group B post-treatment contrasted with pretreatment (P > 0.001) and there was a significant improvement in the BBS Index post-treatment in the group A and B contrasted with that pretreatment (P < 0.001). Between groups, there was a significant improvement in all measures of the study group (A) contrasted with the control group (B).
Conclusion: Sensory-based interventions may be an effective intervention to improve postural stability in subacute stroke patients.
