Abstract
Scoliosis, a condition of unknown etiology, significantly disrupts the locomotor system and alters movement patterns. The prevalence of scoliosis increases dramatically in females after the age of 10. Despite this, there is a paucity of research examining the impact of scoliosis and spinal fusion surgery on functional movements in adult females, particularly during dynamic activities such overhead deep squats (OHDS). This study aims to address this gap by investigating the biomechanical implications of scoliosis on functional movements, with a specific focus on gait and OHDS performance. The research involved movement analysis using a 3D motion capture system to analyze asymmetry. Three groups of female subjects were examined: a surgical group (SG), a non-surgical group (NSG), and a control group (CG). It was hypothesized that scoliosis subjects would demonstrate compromised locomotor efficiency, restricted joint angles, and reduced power generation during gait and OHDS. Results revealed significant differences in temporal-spatial parameters, joint angles, and power generation across the groups supporting the hypothesis. The study also compared pre- and post-surgical movement data of SG. The hypothesis for this comparison was that post-surgical patients will exhibit reduced movement capabilities due to the fixed spinal orientation resulting from spinal fusion surgery. The results indicated no notable changes in joint angles, and temporal-spatial parameters during gait, significant differences were observed during OHDS rejecting the hypothesis. The findings of this study highlighted the need for early, targeted rehabilitation programs tailored to scoliosis severity, focusing on improving joint ROM, stability, and power generation to enhance functional outcomes and minimize complications.
