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.
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.
An AI posture correction app is a mobile tool that uses your phone camera to analyze your posture, identify imbalances, and deliver a personalized corrective exercise and habit plan.
Failing to fix your posture is usually a consistency and feedback problem, not a willpower problem, because the body reverts to old alignment whenever corrective effort is irregular, unguided, or invisible.
Posture correction is the gradual process of retraining muscles, joints, and movement habits to restore your spine's natural alignment, and it typically takes weeks to months depending on severity and consistency.
