Influence of proprioceptive insoles on spinal curvature in patients with slight idiopathic scoliosis.

PURPOSE: Proprioceptive insoles are known to influence the functions of posture and gait by modulations of the sensory structures at the sole of the foot. Literature has shown that they could improve the position of the upper-body in patients with postural complaints of the musculoskeletal system. The aim of this study was to evaluate the influence of proprioceptive insoles on the spinal curvature in patients with slight idiopathic scoliosis.

PATIENTS AND METHODS: Eighteen patients were included in this prospective, single-centre, randomized study. All patients needed to have a relevant growth potential and suffered from a slight idiopathic scoliosis. Two groups were used, where group 1 performed physiotherapy twice a week, whereas group 2 was additionally supplied with proprioceptive insoles. Patients underwent three-dimensional rasterstereography for back-shape analysis. Furthermore, a conventional x-ray imaging of the spine was performed at the beginning and 1 year later to document the curvatures.

RESULTS: There was no statistical difference in the Cobb angles, and in almost all parameters of the rasterstereography, there was no statistically significant change between and within both groups.

CONCLUSION: According to the results of this study, there was no evidence of any statistical significant effect of proprioceptive insoles on spinal curvature in patients with slight idiopathic scoliosis.
