Trunk Muscles Activity of Braced Scoliosis Patients
A multi-electrodes electromyographic (EMG) tech- nique was used to investigate the action mechanisms of the Boston brace (BB) system on the scoliotic spine. EMG activity was measured from the trunk muscles of scoliosis patients during four controlled isometric tasks. Measurements were made with and without the brace. Results showed a brace-induced increase of specific trunk muscle groups. The increase activity of these spe- cific muscles can be beneficial for the correction of scoliosis as predicted by simulations of the trunk biome- chanics. It thus seems that EMG can be used to acquire knowledge on how scoliosis brace treatment can be clinically effective.
