How much extension is typical at the glenohumeral joint?

  1. 30-50 degrees

  2. 50-70 degrees

  3. 70-90 degrees

  4. 90 degrees

The correct answer is: 50-70 degrees

The typical range of extension at the glenohumeral joint is between 50-70 degrees. This range is important as it reflects normal functional movement patterns for the shoulder, which allows for activities such as reaching or throwing. Understanding the biomechanics of the shoulder joint is crucial for safe practice in massage therapy and rehabilitation. It is essential to recognize that excessive extension beyond this range can lead to joint instability and increased risk of injury. The glenohumeral joint has a complex structure that supports a wide range of motion, but its design also imposes certain limitations to ensure stability. When evaluating a patient's range of motion, knowing the typical extension range aids in identifying any dysfunction or compensatory movement patterns that may need to be addressed.
