To determine how the muscle strength of gluteus maximus, abdominal and trunk extensor, the incapacity and pain in patients with low back pain could be influenced by Isostretching method. METHODS: This work consisted on a random clinical trial approach where 18 women were divided into active and control group. Requirements used to make a participant eligible were 18-25 age and at least 5 low back pain by Visual Analogical Scale (VAS) three times a week. Those who subjected to other physiotherapy treatments, recently surgery or other pathology were excluded. The assessments were performed at the beginning, after 10 and 20 sessions by two blind raters, using the Roland Morris'questionnaires, the VAS and the Repetition Maximum Test in one minute. The Shapiro Wilk test, Student's t-test and the ANOVA were used for the statistical analysis. RESULTS: The comparison between initial and final values in the active group to analyze the muscle strength of abdominal, gluteus maximus, the trunk extensors, disability and pain showed p = 0,00 and in the control group p = 0,02 for the gluteus maximus. The analysis of the three stages of assessment for active group showed for the muscle strength of abdominal, gluteus maximus and pain p = 0,00, incapacity p = 0,01 and the extensors of trunk p = 0,80. The control group didn't show any change. CONCLUSIONS: The Isostretching is efficient to reduce the pain and disability, and to increase the muscle strength of abdominal, gluteus maximus and the trunk extensor of patients with low back pain.
