Chronic low back pain is often termed “non-specific” due to the unknown cause of pain. One proposed cause is a lack of “stability” in the spine due to poor control and strength of the deep core muscles. As a means of addressing this, motor control exercises (MCE) were introduced in the 1990’s with some promise. The benefits, however, have been questioned in recent years and more recent studies have found conflicting evidence for the prescription of MCE’s. This is the first Cochrane review on the topic and found that MCE does not result in better outcomes compared to other exercises.
