A study found that in 1744 patients undergoing fusion surgery for adolescent Idiopathic scoliosis, 12% had back pain remaining after recovering from surgery. Rehabilitation prior to spine surgery or prehabilitation (prehab), has been shown to reduce costs and improve functional outcomes in patients who have had total hip or total knee arthroplasties. There is a lack of literature looking at prehab in the context of spine surgeries. The purpose of this study is to see if prehab can improve patient outcomes such as decreased pain, decreased length of stay in the hospital, and improved functional outcomes in patients undergoing fusion surgery for adolescent idiopathic scoliosis.

Adolescent idiopathic scoliosis (AIS) is the most common spinal deformity in adolescents and literature suggests that the link between back pain and AIS is underreported. Core stabilization exercises and scoliosis specific exercises have been shown to increase SRS scores related to pain (higher SRS scores indicate lower levels of pain). Additionally, higher SRS scores at pre-op were associated with a lower risk of residual postoperative pain following a fusion surgery. This suggests that preoperative exercise programs should lead to an increase in SRS pain scores post-operatively however, this direct relationship has not been researched. Rehabilitation exercises prior to surgery has been shown to improve functional outcomes in knee and hip arthroplasties however, the rehabilitation preoperatively has not been studies in the context of spine surgeries. The purpose of this study is to evaluate whether the prehabilitation exercise program can improve post-op outcomes including length of stay, decreased pain, decreased length of stay, and improved functional outcomes.

Inclusion Criteria:

• Included patients will have a diagnosis of AIS (ages 11-18). They will have a curve angle requiring surgery and be on the waitlist for surgery.

Exclusion Criteria:

• Patients will be excluded if they are currently enrolled in a physiotherapy designed exercise program prior to being enrolled in the study.
• They will be excluded if they have additional medical issues, limiting their ability to participate fully in the exercise program.
• Individuals with any cognitive disability that affects their ability to complete the questionnaires or follow instructions for the exercise program will also be excluded.
