Understanding Shoulder Instability: The Latest YouTube Video
The shoulder relies on three things for stability: the shape of the bones, the ligaments and joint capsule, and the surrounding muscles. If any of these are weakened or not working properly, the shoulder can become unstable. One of the first things to check is whether the person has had a dislocation, as this greatly affects treatment and the chance of the problem recurring.
We often group shoulder instability into three types:
• Traumatic instability – usually after a clear injury or dislocation.
• Structural instability – linked to natural joint differences.
• Muscle-patterning instability – when muscles work in the wrong timing or pattern.
After a first-time dislocation, a short period in a sling is helpful, but only for about a week. Early gentle movement and light rotator cuff exercises are important for reducing stiffness and improving control.
For people who haven’t had a dislocation, rehab is usually very successful. Building rotator cuff strength, improving scapular control, and helping the patient find a comfortable and confident movement zone are key steps. Some patients may overuse muscles like the pectoralis major or latissimus dorsi, and gentle stretching or massage can help reduce this.
Psychological factors matter too. Fear, worry, and loss of confidence can make instability feel worse. Clear education and reassurance go a long way in helping someone progress.
With the right exercises and guidance, most people recover well from shoulder instability.
