- Weather that impact the nerves and muscles that control breathing, such every bit amyotrophic lateral sclerosis (ALS), muscular dystrophy, spinal cord injuries, and stroke
- Problems with the spine, such as scoliosis (a curve in the spine). They tin bear upon the bones and muscles used for breathing.
- Impairment to the tissues and ribs around the lungs. An injury to the breast can cause this damage.
