Objective : Scoliosis in cerebral palsy can seriously disturb the patient's daily life. To help alleviate this we developed a new original orthosis and named it the Dynamic Spinal Brace (DSB). In this study, we investigated the effectiveness of the DSB in daily life with patients and caregivers. Methods : We studied 222 cerebral palsy patients treated with the DSB. We carried out a questionnaire survey of the caregivers and measured X-ray results of the scoliosis deformities. Results: In the questionnaire, more than 80% of the patients improved in their sitting position and posture and more than 50 % of the patients improved in the transfer or ambulation assistance and meal assistance requirement by the caregivers. Higher age (over 18 years old) revealed improved muscle tonus. Breathing and muscle tonus showed improvement as scoliosis was advanced. Conclusion : DSB for scoliosis in cerebral palsy showed effectiveness in the sitting position, posture, transfer or ambulation assistance and meal assistance. DSB is also effective for muscle tonus in patients after growth maturity and breathing and muscle tonus in patients with severe scoliosis.
