Overview
Brief Summary
The purpose of the study is to examine the changes in function and performance biomechanics in patients undergoing spinal fusion corrective surgery for adolescent idiopathic scoliosis (AIS).
Detailed Description
Methods will consist of movement studies, questionnaires, and chart review. The recruited subjects will be followed at the usual clinical schedule of pre-op, 6-week, 3 -, 6- and 12-month post-operative follow-up visits. After signing informed consent, age at time of surgery, height, weight, body composition, leg length will be recorded to be used during data processing. Chart review will further yield data on Cobb angle, Lenke Scoliosis classification, instrumentation used during surgery, and level of spinal fusion. All subjects will be asked to complete assessments of activity level (Marx Score, Tegner Activity Score), general health (EQ-5D), and a validated scoliosis survey (Scoliosis Research Study questionnaire SRS-22). Movement studies will consist of the Lower Quarter Y Balance Test (YBT-LQ), and Functional Movement Screen (FMS), and measures of forward flexion, right and left lateral bending, and right and left trunk rotation. These measures will be assessed preoperatively and at postoperative follow-up visits.

Outcomes
Primary Outcomes
Change in Lower Quarter Y-Balance Test (YBT-LQ)
Time Frame: Preoperatively; 6wks, 3mos, 6mos, and 12mos Postoperatively
The YBT-LQ is a test of dynamic balance in unilateral stance that has been deemed to be reliable and valid. The YBT-LQ consists of each patient standing on one leg and reaching as far as they can with their non-stance leg in the anterior, posteromedial and posterolateral direction while standing on the other foot on a centralized stance platform.
Change in Functional Movement Screen (FMS)
Time Frame: Preoperatively; 6wks, 3mos, 6mos, and 12mos Postoperatively
The FMS is a screening tool used to identify limitations or asymmetries in movement patterns by executing seven motions. Activities include a deep squat, lunges, hurdle steps, a push-up, straight-leg raises, shoulder mobility assessments, and rotary stability assessments.
Secondary Outcomes
- Change in Marx Activity Scale(Preoperatively; 6wks, 3mos, 6mos, and 12mos Postoperatively)
- Change in Tegner Activity Scale(Preoperatively; 6wks, 3mos, 6mos, and 12mos Postoperatively)
- Change in EQ-5D(Preoperatively; 6wks, 3mos, 6mos, and 12mos Postoperatively)
- Change in SRS-22(Preoperatively; 6wks, 3mos, 6mos, and 12mos Postoperatively)
