Range of Motion: Spine Flexion

range of motion Jun 29, 2023

Testing Spine Flexion 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 flex forward as far as they can, ensuring their knees are locked straight.
  3. Once maximal range of motion is achieved, hit the pause/play, followed by the save button to view and record the results. NB: We should be aiming for at least 100 degrees of back flexion on this test.

The normal Spine Flexion range of motion can vary depending on a person's age, gender, and overall health. However, generally, we should be aiming for at least 100 degrees of back flexion on this test.
