Range of Motion: Shoulder Horizontal Adduction

Procedure:

To test the Shoulder Horizontal Adduction range of motion with an inclinometer, follow these steps:

1. Have the client start in a seated or standing position, with their arm flexed in front of their body at 90 degrees.
2. Place the smart device on top of the client’s humerus. 
3. As this test involves rotation, the Measurz inclinometer will adopt its transverse plane feature. So, please ensure that the inclinometer is set at 0 degrees before proceeding with this protocol.
4. Once set, instruct the client to horizontally adduct their shoulder across their midline and as far as they can go. When maximal range of motion is achieved, hit the pause, and then the save button to review the results. NB: Ideally aiming for at least 50 degrees of shoulder horizontal adduction in this test.

The normal range of motion for Shoulder Horizontal Adduction can vary depending on factors such as age, sex, and physical activity levels. However, we should be aiming for at least 10 to 20 degrees of shoulder adduction on this test.
