A review on kinematic parameters in scoliotic patients

Abstract

Introduction: Scoliosis is one the most common orthopedic problems in children and adults which is still idiopathic. Scoliosis is a three planar deformity and results in changes in anatomy of spine and pelvic that alters gait parameters. The purpose of this study was to evaluate changes in kinematic parameters in lower limb, upper limb, and trunk in scoliosis patients compared with normal subjects. Determining the exact pattern of these changes and the effect of it's severity on this parameters can be used to check the progression or improvement of scoliosis. Materials and Methods: To find and collect suitable articles some key words like scoliosis, gait, and kinematics were used in data bases such as Google Scholar, Pubmed, Elsevier, Ovid and Springer. Papers were selected based on identified inclusion and exclusion criteria. Then articles were scored by Downs and black tool. Results: Among of twenty five articles, 9 articles were selected on basis of inclusion and exclusion criteria from 1998 to 2012. Step length was the only temporospatial parameter that showed a significant reduction. Kinematic parameters in Lower limb identified reduced range of motion, but motion pattern did not show any significant difference. The most differences in data were observed in trunk and pelvic rotation. It was cleared only in person who has a large curvature of the thoracic spine and the same direction of pelvic rotation. Pelvic changes were not predicted in other cases. Pelvic also indicated some changes in x-ray and according to anatomical relation between pelvic and lumbar, thoracolumbar and lumbar curves had the most effect on the pelvic changes. Conclusion: The majority of these articles investigated walking parameters in different speeds. In order to achieve the comprehensive outcomes, the standard model should exist with regarding a curve type and test condition, especially in the upper limb that has been paid low attention, so far.
