When treating low-back pain, traditional exercises for strengthening abdomen and trunk erector muscles have been criticised for their submitting spinal structures to high loads, thereby increasing the risk of new injury. Recent studies have pointed to the effectiveness of segmental stabilisation in treating low-back pain, less damaging since it is done in neutral position. Current research suggests that, unless the trunk deep stabilizers are correctly activated, recurrence of pain is more often noticed. This is a review of 47 articles and books published between 1984 and 2006, resulting from a search in PubMed database by means of key words lumbar stabilization, lumbar multifidus and transversus abdominis muscles. Literature has established a link between low-back pain and poor control of deep trunk muscles, particularly the lumbar multifidus and transversus abdominis muscles; some studies also point out the quadratus lumborum and diaphragm muscles as lumbar stabilizers. By drawing on the reviewed material, we suggest exercises of subtle and specific synchronized isometric contractions for these lumbar stabilisers, which act directly upon pain relief by increasing lumbar spine stability.
