Thoracic Flexion Syndrome:
Thoracic pain that increases with shoulder flexion, lying supine, and with extension after prolonged flexion. This is due to excessive time sitting in prolonged flexion (sitting slouched at a computer) or excessive strengthening exercises involving the abdominals. This may be a diagnosis of dowagers hump or kyphosis due to osteoporosis.
- Improve strength and activity of the thoracic back extensors without overworking the lumbar extensors.
- Avoid abdominal exercise that shortens the abdominals.
- Change seated posture to improve positioning to decrease thoracic flexion.
- Improve mobility of the pecs
