Although various factors have been attributed to the etiology of idiopathic scoliosis, studies have indicated that the kinematic differences in the spine, pelvis and lower limb may contribute to the causation and progression of idiopathic scoliosis. The aim of this investigation was to identify asymmetries in lower limb kinematics and pelvic and back movements during level walking in scoliotic subjects that can be related to the spinal deformity. The study has employed a movement analysis system to estimate various joint angles in the lower extremities and other kinematic parameters in the pelvis and back. The results of a pilot study have highlighted the potential usefulness of a range of parameters in the indication of asymmetries and their implications for spinal deformity generation. While demonstrating the value that movement analysis systems may have in investigating pathogenesis and aetiology, these preliminary findings indicate that the identified variables can also used in the kinematic analysis of spinal deformities such as scoliosis. Further studies are being undertaken to validate these findings.
