Assessment of muscle strength of hip joints in children with idiopathic scoliosis.

BACKGROUND The choice of an appropriate approach to the treatment of idiopathic scoliosis is considerably complicated owing to the lack of a clear-cut aetiology of this condition. Idiopathic scoliosis impairs the body's biomechanical balance and adversely affects body statics. MATERIAL AND METHODS The muscle torques of the flexor and extensor muscles of the hip joints were assessed in 123 children (96 girls and 27 boys) aged from 8 to 16 with the I degrees scoliosis. Statistically significant differences (p>0.05) were revealed. RESULTS The primary lumbar scoliosis was to the left in 109 patients (Group 1) and to the right in 14 patients (Group 2). All children participated in a 6-month exercise programme to strengthen the weakened muscle groups. Torque measurements were performed twice: immediately after the child joined the rehabilitation programme and on completion of the programme. The strength of the weakened muscles was seen to increase to a statistically non-significant level (p>0.05). CONCLUSIONS 1. Exercises strengthening weakened muscles of the hip joint improve the posture of scoliotic children and can be helpful in treating idiopathic scoliosis. 2. Differences in the strength of the flexors and extensors of the hop joint impair body statics and may constitute one of the causes of idiopathic scoliosis in children.
