Range of Motion: Spine Extension

range of motion Jun 29, 2023

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

  1. Have the client adopt an upright standing position. 
  2. With the Measurz inclinometer aligned with T12 of the spinous process, instruct the client to extend back as far as they can, ensuring their knees are locked straight.
  3. Once maximal range of motion is achieved, or if pain or discomfort starts to occur, hit the pause/play, followed by the save button to view and record the results. NB: We should be aiming for at least 20 to 40 degrees of back extension on this test.

The normal Spine Extension range of motion can vary depending on a person's age, gender, and overall health. However, generally, the normal range for Spine Extension is considered to be between 20-40 degrees.
