The principle of core stability has gained wide acceptance in training for the prevention of injury and as a treatment modality for rehabilitation of various musculoskeletal conditions in particular of the lower back. There has been surprisingly little criticism of this approach up to date. The following statements can be said about core training:
It is correct to say that weak trunk muscles, weak abdominals and imbalances between trunk muscles groups are not a pathology just a normal variation. CORRECT. IT IS POOR ENDURANCE OF TRUNK EXTENSORS THAT IS CLINICALLY SIGNIFICANT.Weak or dysfunctional abdominal muscles will not lead to back pain. THERE IS LIMITED EVIDENCE FOR OR AGAINST THIS.
There is evidence that tensing the trunk muscles is likely to provide protection against back pain & reduce the recurrence of back pain.
Core stability exercises are no more effective than, and will not prevent injury more than, any other forms of exercise or physical therapy. THERE IS SOME EVIDENCE THAT THIS STATEMENT IS TRUE, SOME THAT IT IS NOT.
Core stability exercises are no better than other forms of exercise in reducing chronic lower back pain. Any therapeutic in?uence is related to the exercise effects rather than stability issues. WE JUST DON’T KNOW.
Patients who have been trained to use complex abdominal hollowing and bracing maneuvers should be discouraged from using them. I WOULD NOT AGREE. HOLLOWING HAS ITS PLACE & BRACING IS MOST LIKELY A VERY GOOD WAY TO PROTECT THE BACK DURING HIGH LOADS, ESPECIALLY IN SOMEONE W/ EXISTING LOW BACK PAIN.
