Effects of Vestibular-Oriented Balance Training Versus Motor Dual Task Training on Balance, Postural Control, and Fall Risk in Chronic Stroke SurvivorsIIUI/RERC

Stroke is one of the leading causes of long-term disability worldwide and is associated with significant impairments in balance, postural control, mobility, and functional independence. Balance dysfunction remains one of the most challenging complications in chronic stroke survivors despite conventional rehabilitation interventions.

Vestibular-Oriented Balance Training (VOBT) is an evidence-based rehabilitation approach designed to improve balance by stimulating the vestibular system and enhancing sensory integration. This intervention includes exercises involving head movements, gaze stabilization, balance challenges on stable and unstable surfaces, dynamic postural tasks, and coordinated body movements.

Although both Vestibular-Oriented Balance Training and Motor Dual Task Training have demonstrated beneficial effects individually, there is limited high-quality evidence directly comparing their effectiveness in improving balance, postural control, and fall risk among chronic stroke survivors. Identifying the more effective rehabilitation strategy would assist physiotherapists in selecting evidence-based interventions that optimize patient recovery and functional independence.

The present study is designed as a randomized controlled trial to compare the effects of Vestibular-Oriented Balance Training and Motor Dual Task Training on balance, postural control, and fall risk in individuals with chronic stroke. A total of 50 eligible participants diagnosed with chronic stroke will be recruited using predefined inclusion and exclusion criteria. Participants will be randomly allocated into two parallel intervention groups using a computer-generated randomization sequence.

Participants allocated to the experimental group will receive Vestibular-Oriented Balance Training in addition to conventional physiotherapy. The intervention will consist of progressive vestibular exercises including gaze stabilization, head movement exercises, balance training on different support surfaces, weight-shifting activities, dynamic standing balance tasks, reaching activities, stepping exercises, and functional gait activities. The intensity and difficulty of the exercises will be progressively increased according to each participant's performance and tolerance throughout the intervention period.
