Application of 3D scanner to measure physical size and improvement of hip brace manufacturing technology in severe cerebral palsy patients

Abstract

Abstract This prospective pilot study aimed to develop a personalized hip brace for treating hip subluxation in children with cerebral palsy. Nineteen children, aged 1 to 15, with severe cerebral palsy participated in the study. Customized hip braces were created based on 3D scanner measurements and worn for seven days. The primary outcome, Hip Migration Index (MI), and secondary outcomes, including range of motion (ROM) in the hip and knee joints, pain intensity, satisfaction, discomfort scores, CPCHILD, and wearability test, were assessed. The MI and ROM were assessed at screening and at Visit 1 (when the new hip brace was first worn), while other indicators were evaluated at screening, Visit 1, and Visit 2 (seven days after wearing the new hip brace). The study demonstrated significant improvements in the MI for the right hip, left hip, and both sides. However, there were no statistically significant differences in hip and knee joint ROM. Other indicators showed significant changes between screening, Visit 1, and Visit 2. The study suggests that customized hip braces effectively achieved immediate correction, positively impacting the quality of life and satisfaction in children with cerebral palsy. Furthermore, the braces have the potential to enhance compliance and prevent hip subluxation.
