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.
Prolonged sitting damage is the gradual breakdown of spinal disc health, muscle balance, and posture that occurs when the body stays seated for extended periods without regular movement breaks.
Sitting vs standing for lower back pain is a load distribution question: sitting overloads the lumbar discs and posterior structures, while standing overloads the lumbar extensors and posterior chain muscles.
Lower back pain from sitting is a postural and mechanical condition where prolonged hip flexion, pelvic tilt, and disc compression overload the lumbar spine, causing pain that worsens the longer you sit.
