Comparison of Single Session Auditory Versus Visual Feedback on Performance and Postural Balance in Hemiplegic Children With Cerebral Palsy

Abstract

BACKGROUND:  Cerebral palsy (CP) is a pediatric disorder characterized by a motor impairment resulting from a permanent, non-progressive lesion in the brain. Cerebral palsy is marked by movement and postural control impairments, which greatly affect body structure, function, daily activities, and participation. OBJECTIVE: To compare the single-session auditory versus visual feedback on performance and postural balance in children with hemiplegic cerebral palsy. METHOD: The study was a crossover clinical trial involving a group of 25 patients diagnosed with CP hemiplegia, aged between 6 and 12 years, including both genders. Each patient underwent conventional balance therapy followed by either auditory feedback or visual feedback intervention. After a 48-hour wash-out period, they received conventional balance therapy again before undergoing the alternative intervention initially assigned. The Modified Ashworth scale (MAS), pediatric balance scale (PBS), timed one-leg stance, time up and go test (TUG), and center of pressure (CoP) displacements were assessed as the outcome measures before and after the interventions. RESULTS: Based on the one-leg stand test, TUG, and CoP displacement outcome measures results, both interventions improved balance time, speed of movement, and postural stability in children with hemiplegic spastic cerebral palsy (P < 0.05). Moreover, after a single session of the intervention, the visual feedback group demonstrated a significantly greater improvement in the TUG test, one-leg stand test, and CoP displacement compared to the auditory group (P < 0.05). CONCLUSIONS: The results of the study suggest that combining auditory or visual feedback with conventional balance therapy is effective in treating children with hemiplegic spastic cerebral palsy; furthermore, the utilization of visual feedback would be more effective. Further research is needed to determine the long-term effects of visual and auditory feedback on the assessed outcome measures.
