The problem of the effect of adolescent idiopathic scoliosis on the functional condition of the lower limb muscles is still highlighted insufficiently.Aim. Analysis of the degree of involvement of the lower limb muscles in the pathological process in adolescents with idiopathic scoliosis.Methods. A comparative analysis has been made on the results of examination of 209 adolescents: 25 adolescents with idiopathic scoliosis; 170 normal adolescents; 14 adolescents with congenital scoliosis. The moments of force ofthe lower limb muscles were evaluated using dynamometric stands. Electrophysiological characteristics of the lower limb muscles were registered by the method of global and stimulation electroneuromyography.Results. The decrease in the amplitude of voluntary EMG of the femoral muscles in adolescents with idiopathic and congenital scoliosis is accompanied by dropping the moments of force relative to the values of the control group. The leg muscles are characterized by the preservation of the values of force at the level of normal test subjects under the conditions of the reduced voluntary EMG of high frequency. The amplitude of the M-responses of the indicator muscles and the values of the excitation propagation velocity along the motor fibers were also preserved. There are no statistically significant correlations between the amount of the spine deformity, on the one hand, and the values of asymmetry of the characteristics of the muscles in adolescents with idiopathic scoliosis.Conclusion. In adolescents with idiopathic scoliosis the function of femoral muscles is decreased, and there is no relationship between the amount of the spine deformity and the values of asymmetry of the characteristics of the lower limb muscles. The similar character of muscle function changes in adolescents with idiopathic and congenital scoliosis can testify that the cause of the observed changes is not the disease etiology, but the insufficient level of motor activity.E.
