BACKGROUND AND OBJECTIVES: The inability to stabilize the spine due to the unbalance between trunk extensor and flexor muscles is a strong indication of the development of lumbar spine disorders. The exercise commonly referred to as Pilates® advocates improvement of muscle agonist and antagonist relations favoring the work of stabilizing muscles and preventing several lumbar spine disorders. This study aimed at evaluating the effectiveness of Pilates to treat chronic low back pain. CASE REPORTS: We have evaluated seven female patients aged between 18 and 50 years, with clinical diagnosis of chronic low back pain and able to perform basic and intermediate Pilates exercises. Evaluation tools were the pain visual analog scale (VAS) and Oswestry's low back pain questionnaire, in addition to an Identification Questionnaire. Data were analyzed by simple arithmetic average. There has been significant pain improvement by VAS which initially had a mean of 7 and after 3 months of treatment has decreased to 1.7. There has been improvement in quality of life, with Owestry's index decreasing from 36.8% to 8% after 3 months of treatment. CONCLUSION: Pilates was effective to treat chronic low back pain, having improved pain and incapacities.
