Prone Instability Test | Rationale & Interpretation

The video tutorial explains the prone instability test, a diagnostic tool for patients with low back pain. It categorizes patients into treatment groups based on their symptoms, such as hypermobility or instability. The test involves positioning the patient in a prone position, applying PA forces to the lumbar spine, and checking for pain reduction when the patient moves to an active position. Muscle activation, particularly of the lumbar paraspinals and core, plays a crucial role in stabilizing the hypermobile segment, leading to pain reduction and a positive test result.
