THEORY | Subacromial Impingement

The video tutorial discusses three types of shoulder impingement: subacromial, secondary, and internal. It explains the mechanisms and causes of primary impingement, including mechanical factors and muscle imbalances. The video also covers diagnostic tests for primary impingement and compares secondary and internal impingement, highlighting differences in symptoms and underlying causes. Secondary impingement is associated with laxity and instability, while internal impingement involves posterior shoulder pain and is common in athletes.
