A thoracic mobility self-test is a set of simple, unweighted movements used to check how freely your mid-back extends, rotates, and flexes without your lower back or shoulders taking over the movement.
Thoracic mobility is the range of motion available in the mid-back (T1 to T12), specifically its ability to extend, rotate, and flex without the neck or lower back taking over the movement.
Stress and tension between the shoulder blades is upper-back muscle tightness caused by the body's stress response, which makes you hunch, hold your breath, and clench the muscles around your neck and shoulders.
Pain between the shoulder blades from sleeping is upper-back stiffness or ache caused by a poor sleep position, an unsupportive pillow, or a sagging mattress that leaves your mid-spine and shoulders unsupported overnight.
For most posture-driven pain between the shoulder blades, an AI posture app or physiotherapy outperforms generic exercises, because both add the personalization and feedback that random routines lack.
