Cervical-thoracic spine and change of its shape due to posterior muscle chain and tilt of the pelvis
Abstrakt
Poor posture is the result of musculoskeletal distortion in the neck, and lower and upper back. Upright posture of the cervical-thoracic spine was done with the activity of the muscle chain latissimus dorsi, with the tested movement of the external rotation and adduction of the arms.
Posture of the cervical-thoracic spine was evaluated in the sagittal plane. Twenty subjects (4 man: 24,5 +- 4,3 years; 16 female: 24 +- 2,5 years) without pathology or injury of the pelvis, shoulder girdle and spine were recruited.
The posture of the cervical-thoracic spine and the inclination of the pelvis were measured with the kinem atic analysis. The Z axis intersected TH1-TH12-SIPS in the case of the upright posture of the cervical-thoracic spine.
High correlation (Pearson r = - 0,96; p < 0,01) was achieved between the inclination of the pelvis and the upright posture of the cervical-thoracic spine. The upright posture of the cervical-thoracic spine was created only if there was the neutral position of the pelvis.
