Abstract:Objective To observe the therapeutic effect of physical therapy scoliosis-specific exercise (PSSE) on the mild adolescent idiopathic scoliosis (AIS). Methods A retrospective analysis was performed on the clinical data of 44 patients with mild AIS admitted to Rehabilitation Department of Tianjin Hospital for PSSE therapy from October 2018 to October 2019. Before and after treatment, Cobb angle, angle of trunk rotation (ATR), the degree of vertebral rotation (measured with Nash-Moe method) and Oswestry disability index(ODI) questionnaires were evaluated, and the therapeutic effects were observed and analyzed. Results After 24 weeks of PSSE treatment, Cobb angle ［(18.77±4.64)° vs (10.75 ± 4.40) °, t=10.517, P<0.01］ and ATR ［(8.43 ± 2.16) ° vs (5.09 ± 1.25) °, t=11.084, P<0.01］ were significantly improved compared with those before treatment. Compared with that before treatment (0 case of degree 0, 7 cases of degree Ⅰ, 33 cases of degree Ⅱ, and 4 cases of degree Ⅲ) ,the Nash-Moe classification of vertebral rotation degree after treatment (18 cases of degree 0, 22 case of degree Ⅰ, 4 cases of degree Ⅱ, and 0 cases of degree Ⅲ) was significantly decreased (Z=7.085, P<0.01). ODI score significantly decreased compared with that before treatment (17.70±5.25 vs 39.82±4.80, t =20.603, P =0.01). Conclusion PSSE can stabilize and improve mild AIS, and it′s a more scientific and reasonable treatment method for mild AIS.
