Frozen shoulder is caused by scar tissue formed inside the space of the glenohumeral joint with reduced synovial fluid. This condition usually occurs after repeated tearing of soft tissue surrounding the joint, or it may be caused by scar tissue formed after shoulder injury or by adhesion after surgery. The joint capsule appears to be a major source of limitation of movement in this condition. A dull, aching pain is felt in the shoulder when the arm is lifted, and it often gets worse at night.
Accompanied by other therapies, dry needling acupuncture is a helpful modality for this injury, including cases in which surgery is required. Needling can be applied to all the tender and painful tissues and their associated musculature, twice per week.
