Thoracic mobility tools are simple, low-cost props, foam rollers, peanut-shaped massage tools, and mobility sticks, used to apply pressure or leverage to the mid-back so it can move through extension, rotation, and flexion more freely.
Sciatica is irritation of the sciatic nerve that sends pain, tingling, or numbness from the lower back or buttock down one leg, and sitting makes it worse by compressing the nerve and the muscles around it.
The best desk setup for pain between the shoulder blades keeps your monitor at eye level, your elbows supported near 90 degrees, and your screen close enough that you never lean forward, so the muscles between your shoulder blades stop holding you up all day.
Neutral sitting posture is a seated position where the spine keeps its natural curves, the pelvis stays balanced, and load spreads evenly across the lower back rather than concentrating in one area.
Ergonomic seating refers to chairs and desks designed to support a neutral spine and reduce the mechanical load that prolonged sitting places on the lower back.
