Summary
Overview
Drs. Chris and Zand dive into shoulder health, exploring common causes of shoulder pain and practical ways to maintain shoulder strength and mobility. They speak with physiotherapist Kate Haynes, who works with both humans and horses, about impingement, rotator cuff tears, and frozen shoulder. The episode emphasizes that simple exercises like wall press-ups and pendulum movements can significantly improve shoulder health, and that maintaining good posture is crucial for preventing shoulder problems.
The Shoulder as the Most Mobile Joint
Kate establishes that the shoulder is the most mobile joint in the human body, which explains both its versatility and vulnerability. From making snow angels to arm wrestling, from reaching high shelves to using our hands expressively while talking, the shoulder enables an enormous range of movements. This mobility comes at a cost - the joint sacrifices stability for flexibility, making it more prone to problems than more constrained joints.
- The shoulder is definitively the most mobile joint in the body with the biggest range of movement
- Whatever your hands are doing, your shoulders are involved in movement or stabilization
- In cultures where people gesture extensively, like Southern Europe, shoulders are very actively involved even though we think of it as hand movement
- The shoulder's complexity comes directly from its extensive mobility
" Whatever your hands are doing, your shoulder is going to be having to do some form of movement or stabilising. "
Understanding Common Shoulder Problems
Kate Haynes explains the three most common shoulder conditions she treats: impingement, rotator cuff tears, and frozen shoulder. Impingement occurs when the shoulder blade doesn't move properly out of the way as you lift your arm, causing painful pinching. This often results from postural issues and muscle imbalances rather than structural damage. The condition creates a characteristic "painful arc" where lifting the arm out to the side is particularly uncomfortable.
- Impingement is the most common shoulder problem, caused by muscle imbalance where the shoulder blade doesn't move out of the way properly
- The condition creates a "painful arc of movement" particularly when taking the arm up and out to the side
- Patients with impingement characteristically hitch their shoulder up to their ear and try to launch the arm up rather than moving smoothly
- Frozen shoulder (adhesive capsulitis) involves the joint capsule itself becoming stiff and can take up to a year to resolve
- Rotator cuff tears can occur from micro-tears over time in manual jobs, leading to progressive pain and weakness
" It's a really complex joint because it has so much movement. "
