Effects of Vestibular Sensory Stimulation Training on Seated Postural Balance and Trunk Control in Subacute Stroke Patients

PURPOSE: This study examined the effects of vestibular stimulation on the trunk control and sitting balance in subacute stroke patients and evaluated whether adding vestibular stimulation to neurodevelopmental therapy (NDT) provides additional therapeutic benefits.METHODS: Twenty subacute stroke patients were assigned randomly to an experimental group (NDT plus vestibular stimulation, n = 10) or a control group (NDT alone, n = 10).Both groups received the intervention for four weeks.Trunk control and sitting balance were assessed before and after the intervention using the Modified Functional Reach Test (M-FRT) with the Balancia software system and the Trunk Impairment Scale (TIS). RESULTS:The between-group comparisons showed that the experimental group had a significantly greater post-intervention M-FRT forward reach distance and
