Brief Summary

Scoliosis is a complex three-dimensional deformity of the spine, of uncertain etiology, but multifactorial and mainly involves characteristic changes in the sagittal plane also, changes in the coronal plane, and varying degrees of vertebral rotation in the axial plane. In recent studies, pre-scoliotic changes are also examined. Some risk factors for the development of scoliosis include gender, age, ethnicity, and family history. Since apical rotation, gibbosity, and costa vertebral angle are considered to be associated with rotation in the literature, these parameters have been defined as risk factors for the progression of the curve. Cobb angle, Risser sign, and chronological age are taken as the basis to determine the progression of scoliosis.The onset, progression, and treatment of scoliosis include biomechanical changes and parameters. Structural changes, biomechanical changes, and asymmetries develop between the concave and convex sides. Some studies show that paravertebral muscle asymmetry is caused by the curvature of the spine. Trapeze, LD (latissimus dorsi), and erector spine muscles are examples of paravertebral muscles affected. The LD is a large, smooth muscle lining the lower posterior rib cage and is one of the paravertebral muscles most commonly affected in scoliosis. LD has shoulder, lumbar spine, and sacroiliac joint connections. Scapula, rib cage, and lumbar region deformities seen in scoliosis can be explained by LD. This may make LD a significant cause of scoliosis. In addition, dynamic and static muscle activation rates of LD should be considered in the diagnosis of scoliosis.In the treatment of scoliosis, treatment methods such as physiotherapeutic scoliosis-specific exercise (PSSE), corset, surgery, EMG biofeedback, and neuromuscular training are used.This asymmetry observed in the paraspinal muscles of individuals with scoliosis made us think that we should analyze the LD muscular activations in more detail. The aim of our study is to examine the muscle activation values of the lateral and medial parts of the LD during isometric exercises.

Interventions

Evaluation of Muscle Activation OTHER

Evaluation of Muscle Activation The sEMG device, which is a surface EMG system (Myomonitor, Delsys Inc, Boston, MA), was used to measure the lateral and medial muscle activation levels of the latissimus dorsi. Electrode placement was determined according to SENIAM (Surface Electromyography for Non-Invasive Evaluation of Muscles) criteria. Evaluation of the Gibbosity Trunk rotation (gibbosity) assessments were performed using Adam's test and using a scoliometer . The bending test (Adam's test) is performed in both standing and forward bending positions. The standing version was used in our study.Each measurement equal to 0° on the scoliometer was defined as symmetry at the measured level of the trunk. All other scoliometer values were defined as asymmetry. Evaluation of the Cobb Angle Cobb angles of the curves of the individuals participating in the study were measured with the MicroDicom application.
