Effect of sling exercise combined with Schroth therapy on adolescents with mild idiopathic scoliosis: A twelve-week randomized controlled trial.

ABSTRACT

BACKGROUND: Adolescent idiopathic scoliosis (AIS) is the most common structural deformity of the spine during adolescence, which could cause varying degrees of physical and mental damage to patients. Schroth therapy and sling exercise are widely used in the treatment of patients with AIS currently, and have shown the significant therapeutic effect relatively. OBJECTIVE: To observe the efficacy of sling exercise combined with Schroth therapy on adolescents with mild idiopathic scoliosis (MIS). METHODS: Sixty patients with AIS were randomly divided into the Schroth+sling group (n= 31) and the Schroth group (n= 29). Patients in both groups received Schroth therapy, and sling exercise was added in the Schroth+sling group. Before and after 12 weeks of treatment, the Cobb angle, angle of trunk rotation (ATR), Scoliosis Research Society-22 (SRS-22) scale score and averaged electromyography (AEMG) of bilateral paraspinal muscles were evaluated. RESULTS: After the treatment, Cobb angle, ATR in both groups were decreased compared with those before (P< 0.001), and the decrease in the Schroth+sling group was more obvious (P< 0.05). The AEMG of bilateral paraspinal muscles and the total score, posture, mental health of SRS-22 of the two groups improved compared with those before treatment (P< 0.05), and the Schroth+sling group had a significant improvement than the Schroth group (P< 0.05). CONCLUSION: Schroth therapy improved the degree of scoliosis, torticollis, quality of life, and bilateral paraspinal strength on adolescents with mild idiopathic scoliosis. The effect was more pronounced when the sling exercise was included in the treatment regimens.
