| Popis: | STUDY DESIGN Prospective Cohort Study. OBJECTIVE The aim of this study was to 1) determine postural stability and spatiotemporal gait parameters and 2) characterize dynamic stability and variances in AM of preoperative CSM patients compared to healthy controls. SUMMARY OF BACKGROUND DATA Cervical spondylotic myelopathy (CSM) is the most common cause of spinal cord dysfunction in the world and can lead to significant functional deficits including proprioception and gait disturbances. Biomechanical feedback mechanisms compensating for these deficits, specifically angular momentum (AM) regulation, have remained largely unexplored. METHODS 56 subjects: 32 preoperative Nurick grade 2 or 3 CSM patients and 24 controls were included. Standing balance trials were performed on a single force plate, while walking trials were conducted at self-selected pace over a 15m runway and a series of five force plates. All trials were recorded with 3D motion analysis cameras and gait modeling software was utilized to calculate stability, spatiotemporal gait parameters, and joint kinematics. RESULTS Tilted ellipse area, a measure of center of pressure variance and postural stability, was significantly greater among CSM patients (847.54 ± 764.33mm2 vs. 258.18 ± 103.35mm2, p |
