The muscle is shaped like a rhombus. It is flat and lies under M. Trapezius, which almost completely covers the muscle. The fiber direction goes from the processus spinosus C7-Th1, downwards laterally towards the medial margin of the scapulae. but above basis spina scapulae. This fiber direction causes the muscle to primarily adduce the shoulder blades. It does affect the cervical spine because it has connection to the vertebrae of the cervical spine.
- Common with pain in this muscle during office work in combination with high stress and static work.
- A thoracic spine with increased kufos can give increased tension and pain in this muscle.
- Trigger points can give a burning or numb feeling in the area.
- Remember to soften the antagonist M. Pectoralis major in case of pain in this area.
- This muscle can give pain in the neck
- This muscle can limit range of motion in the neck if it is to tense.
- Massage in various forms
- Dry needling
- Joint manipulation
- Stretch (both at home and from a therapist)
