Frozen Shoulder: What Is It Exactly, and How Can Exercises Help When Movement is Painful?
Frozen shoulder (also known as adhesive capsulitis) can cause pain, stiffness and a significant loss of shoulder range of motion. In this episode, biomechanist Katy Bowman and biologist Dr Jeannette Loram explain what’s actually happening inside the shoulder capsule during frozen shoulder. They discuss the different stages of the condition — including the freezing, frozen and thawing phases — as well as its connections with inflammation, menopause and diabetes. They also explore why movement matters for shoulder health, and during recovery from frozen shoulder. To understand how movement can affect the shoulder capsule, it’s important to distinguish between movement in the shoulder and movement of the shoulder. Katy and Jeannette also look at everyday habits that may limit capsule movement and share some practical daily movements for maintaining shoulder mobility. Plus, they answer a listener's question about using hand paddles when swimming.
