Range of Motion: Neck Extension

 Testing Neck Extension range of motion with an inclinometer involves the following steps:

1. Have the client adopt an upright seated or standing position. 
2. Place the Measurz inclinometer on top of the client’s head, and then instruct them to extend their neck backward as far as they can.
3. Once maximal range of motion is achieved, hit the pause, and then the save button to generate and view the results. NB: Should see a result of at least 75 degrees of neck extension.

The normal range of motion for Neck Extension can vary depending on several factors, including age, gender, and overall health. However, generally, the normal range for Neck Extension is considered to be of at least 75 degrees.
