Balance is the ability to maintain the body in equilibrium with gravity both statically (e.g. while stationary) and dynamically (e.g. while walking). Persons with balance / coordination deficits due to trauma, disease, stroke or other impairment are assisted through physical therapy in improving their balance by following individual treatment plans established by a physical therapist after a thorough evaluation. Treatment plans may include balance activities, sensory training, ambulation training possibly with an assistive device, therapeutic exercise and modalities as appropriate.
