Abstract

Introduction: Low back pain (LBP) is usually defined as pain and discomfort, localized below the costal margin and above the inferior gluteal fold, with or without referred leg pain.

This pain is a common musculoskeletal disorder affecting 80% of people some time in their lives. Low back pain is defined chronic (Chronic Low Back Pain) if the problem persisted for at least three months. Many studies show that specific causes for LBP are uncommon, less than 15% of all low back pain. While other studies show that a relevant fraction of a specific low back pain it would in fact be caused by a functional instability. It’s estimated between 15 and 30% of all CLBP.

Anatomophysiology: Panjabi, described the stabilizing system of the spine as divided into three subsystems: 1) The spinal column 2) The spinal muscles and 3) The neural control unit; spine stability depends on the complex interplay of these three systems.

Disturb in one or more of these three stabilizing mechanisms lead to spinal segments moving outside of their normal range of motion (the neutral zone), causing tissue injury and initiating LBP. There are many important myofascial structure involved in this functional instability: the abdominal muscle, the spinal multifidus, the transversus abdominis muscle, and the pelvic floor.

Clinical Presentation and Tests for Functional Instability: The patients with functional lumbar segmental instability have a characteristic clinical presentation and there many tests useful in identifying this kind of dysfunction.

Conclusion: Many tests, like: prone instability test, passive lumbar test, instability catch sign, painful catch sign, prone Instability test, albeit with considerable differences between them, show a fair degree of reliability in identifying patients with low back pain due to functional lumbar segmental instability.

Therefore the clinician should use them routinely in case of suspicion of this type of dysfunction.
