Which muscle is associated with trigger points that can cause frozen shoulder?

The subscapularis muscle is known to be significantly associated with trigger points that can lead to frozen shoulder, also known as adhesive capsulitis. Frozen shoulder is characterized by stiffness and pain in the shoulder joint, which can severely limit its range of motion.

The subscapularis is one of the rotator cuff muscles and plays a crucial role in shoulder stability and movement. When trigger points develop in this muscle, they can refer pain to the shoulder area, contributing to the overall discomfort and the symptomatic presentation of frozen shoulder. The presence of trigger points can lead to muscle tightness and restriction, which may contribute to inflammatory processes and joint immobility.

This connection highlights the importance of assessing the subscapularis when treating patients with shoulder dysfunctions, as addressing these trigger points may relieve symptoms and enhance mobility. Understanding the role of the subscapularis in the context of frozen shoulder can inform effective treatment strategies in massage therapy and rehabilitation.
