Paper Title:
A Study on Dynamic Hip Brace with Variable Hip Abduction and Adjustable locking Mechanism in patients with Spastic Diplegic Cerebral Palsy: A Prototype
Background: Cerebral palsy (CP) is a term used to describe a problem with movement and posture that make certain activities difficult which results from damage to part of the brain. Among the different types of CP, Spastic CP is the most prevalent, accounting for approximately 70% of cases. This is characterized by increased muscle tone in the upper limbs and the lower limbs. Many children with CP exhibit a crouch gait, a movement pattern characterized by excessive flexion of the knee in terminal swing and throughout the stance phase of the gait cycle. If left untreated, this pathological gait pattern increases the cost of locomotion and tends to worsen over time. In this study, a dynamic hip brace was designed which enables controlled hip abduction, aiming at reducing scissoring gait, and facilitating anterior pelvic rotation for improved postural alignment.
Methods: The Dynamic hip brace was fabricated using polypropylene and incorporated an adjustable mechanical joint. The joint components were manufactured using Polylactic acid (PLA) material through a 3D printing process utilizing an ENDER-3 Pro 3D printer.
Results: The prototype dynamic hip brace provides controlled hip abduction at fixed angular intervals and restricts excessive adduction during functional activities. The brace geometry and joint mechanism show the ability to influence pelvic alignment and lower-limb posture, indicating possible benefits for postural control and gait correction.
Conclusions: It is concluded that the proposed dynamic hip brace with variable hip abduction and adjustable locking mechanism provides an innovative solution to children with spastic diplegic CP to overcome the scissoring gait and adductor tightness. Further the study demonstrates the potential of the brace as a supportive aid for improving functional posture and mobility.
