Effects of balance training combined with Schroth therapy on adolescents with mild idiopathic scoliosis: A six-week randomized controlled trial

BACKGROUND: Adolescent idiopathic scoliosis (AIS) has a great negative impact on the physical and mental health of patients; thus, a range of effective, timely interventions are urgently needed. Currently, there is a lack of evidence to illustrate the effect of balance training in patients with AIS, and the traditional AIS therapy often ignores the recovery in balance function of patients with AIS. OBJECTIVE: To investigate the effect of balance training combined with Schroth therapy among adolescent with mild idiopathic scoliosis. METHODS: 59 adolescents (aged 10 to 18, 35.59% male) with idiopathic scoliosis were selected and divided into an intervention group (n= 30) and a control group (n= 29). Participants in both groups received routine rehabilitation treatment based on Schroth therapy, and balance training was added in the intervention group. The duration of treatment for both groups was 6 weeks. The Trunk Rotation Angle (ATR), Cobb angle, Scoliosis Research Society 22 (SRS-22) scale and balance function of the two groups were evaluated at baseline and after the intervention. RESULTS: No significant difference of outcomes were observed between groups at baseline (P> 0.05). After 6 weeks of intervention, the ATR, Cobb angle, SRS-22 and balance function of the two groups improved significantly compared with those before treatment (P< 0.05), and the intervention group had a significant improvement than the control group (P< 0.05). CONCLUSION: Balance training combined with Schroth therapy for adolescents with mild idiopathic scoliosis can significantly improve ATR, Cobb angle and quality of life, as well as overall balance function.
