UCS happens when the muscles in the neck, shoulders, and chest become deformed, often as a result of continual poor posture especially standing or sitting for long periods of time with the head pushed forward.
The deformed muscles associated with UCS are caused by tightness of the upper trapezius, levator scapula, pectoralis major and minor, and deep cervical flexors (neck muscles). In turn, these deformations put stress on the surrounding muscles, tendons, bones and joints, causing people to experience:
- Neck pain
- Pain, numbness, and tingling in the upper arms
- Headache
- Strain in the back of the neck
- Pain in the upper back and shoulders
- Tightness and pain in the chest
- Fatigue
- Lower back pain
- Trouble with sitting and trouble driving for long periods
- Restricted movement in the neck and shoulders
- Pain and reduced movement in the ribs
