Multiple sclerosis often causes balance disturbance, cognitive decline, and reduced quality of life. Motor imagery and vestibular rehabilitation are established methods in MS care, but their effects have only been studied separately. This randomized controlled trial introduces a combined program of motor imagery and vestibular training to explore whether their integration provides broader benefits. The study will recruit patients with relapsing-remitting MS, apply an 8-week intervention, and compare outcomes in cognition, balance, physical performance, and quality of life against conventional therapy.
