Range of Motion: Shoulder Adduction

Shoulder Adduction range of motion can be tested with an inclinometer by following these steps:

1. Have the client adopt a seated or standing position with one arm locked straight in front of their body, with their thumb facing up to the ceiling.
2. Once set, instruct the client to adduct their shoulder across the midline of their body. 
3. When full range of motion is achieved, or they begin to experience pain or discomfort, press the pause and then save button to view the results. NB: Aiming for at least 10 to 20 degrees of shoulder adduction on this test.

The normal range of motion for shoulder adduction is considered to be between 10 to 20 degrees. However, the exact normal range can vary depending on factors such as age, sex, and individual anatomical differences.
