Quantified trunk rotational strength training has shown promise as a non-operative management option for individuals with AIS. The purposes of our study are to test whether a quantified trunk rotational strength training protocol can increase trunk strength and stabilize or decrease curve size. Seven adolescents with AIS (5 female 2 male; mean 14 yrs +/- 2.6 yrs; mean Cobb 28 degrees +/- 6 degrees range 20 degrees -37 degrees) underwent four months of supervised trunk rotational strength training, and repeat strength test. Trunk strength in both directions increased significantly after training (p<0.05). Average Cobb angle decreased to 23 degrees +/- 11 degrees (range 6 degrees -35 degrees). Four individuals showed reduction (>5 degrees) in their original curve, and 3 remained the same (+/-5 degrees). The strength training protocol significantly increased isometric rotational strength and scoliosis was stabilized short term.
