Symmetrical analysis of paravertebral muscles during superman exercise in patients with adolescent idiopathic scoliosis.

Abstract

To investigate the asymmetry of paravertebral muscles during the superman exercise in patients with adolescent idiopathic scoliosis, and to analyze the applicability of this exercise for the rehabilitation of these patients from the perspective of muscle electromyographic activity. 37 patients with adolescent idiopathic scoliosis are selected for this study. Surface electromyography signals of the bilateral paravertebral muscles during the daily sitting and the superman exercise are recorded. The differences in Surface electromyography of the bilateral paravertebral muscles are analyzed using the root mean square method and the paraspinal muscle symmetry index. The results show that there is no significant difference in the paraspinal muscle symmetry index between the two states. Specifically, 29 patients exhibit the same paraspinal muscle symmetry index, 2 patients have similar indices, and 6 patients display different indices. The root mean square of the convex side paravertebral muscles is generally higher than that of the concave side. In this study, the activation level of paravertebral muscles during the superman exercise is similar to that during the daily sitting, with the activation level on the convex side being higher than that on the concave side. This indicates that the superman exercise is not suitable for the rehabilitation of patients with adolescent idiopathic scoliosis and may even exacerbate the condition.
