The purpose of present study was comparatively evaluating patients with first-episode low back pain and healthy subjects to predict disability and chronicity after six weeks with spinal muscle endurance tests. Materials & Methods: Through an analytical, cross sectional and case – control study in the first stage of research Eliot’s spinal endurance tests were used to evaluate endurance. Disability and pain were used to assess recovery. The study was conducted in two groups of patients (n=32) and normal subjects (n=51) using non-randomized simple sampling. In the second stage, a longitudinal prospective study was done. Studied variables were compared in recovered and non recovered patients after six weeks. Data were analyzed by using Kolmogorof – Smirnoff test, independent T test and Chi-Square. Results: The results of independent t tests showed lower muscular endurance in patients compared to normal individuals (P %> http://rehabilitationj.uswr.ac.ir/article-1-175-en.pdf %P 6-13 %& 6 %! %9 Original %L A-10-1-167 %+ Department of Physiotherapy, Faculty of Phisical Education and Sport Sciences.
