Bracing is the most commonly used non-surgical treatment for adolescent idiopathic scoliosis (AIS) and requires an extensive commitment on the part of the patient and family. However, demonstrating efficacy of brace treatment for AIS has been hampered by the lack of compressive information about wear characteristics. The first 6 months is considered a critical time to evaluate whether AIS patients will commit to the treatment and may predict the treatment outcome. The characteristics of brace wear can assist clinicians to provide better support and aid long term compliance with treatment. This study describes the first 6 month brace wear characteristics in 15 AIS patients (12F;3M) who were prescribed full-time brace wear. There was a statistically significant increase in wear time (p = 0.02) after brace fitting and the brace wear tightness stabilized after month 4. The force at the major pressure pad area continuously decreased after month 2. A moderate correlation was found between the (quantity * quality) of the brace wear at month 6 and the change of Cobb angle (first out of brace - pre brace) (r2 = 0.47). The more time that the brace was worn and the higher proportion of time worn at the prescribed tightness or above improves the likelihood of a better treatment result.
