Stretching for back pain loosens tight muscles for short-term relief, while core strengthening builds the deep-muscle stability that produces lasting relief, which means the two solve different halves of the same problem.
Adjacent segment stress is the added movement demand placed on the spinal segments directly above and below a fusion, since the fused level itself can no longer move, that movement has to happen somewhere.
Thoracic mobility for rotational athletes is the mid-back's capacity to rotate independently of the hips and lower back, providing the range needed for a full, powerful swing, serve, or throw.
Thoracic mobility exercises for seniors are age-adapted movements that restore extension, rotation, and flexion in the mid-back, modified with seated, wall, or chair support to reduce fall risk and bone-loading concerns common after 65.
Thoracic mobility is your mid-back's active range of motion through extension, rotation, and flexion, while thoracic flexibility is simply how far the surrounding muscles can passively lengthen under a stretch.
