Eighty five per-cent of the chronic low back pain is clas-sified as "non specific". The aim of the pre-sent study was to investigate the relation-ships between pain intensity or disability level and musculoskeletal conditions. Materials & Methods: Ninety patients diag-nosed as nonspecific chronic low back were recruited for this study. Flexibility of some important lumbopelvic muscles was meas-ured with a goniometer and endurance of trunk flexors and lateral flexor muscles was evaluated with static flex endurance and static side bridge endurance tests, respect-ively. Also, pain intensity and disability levels were measured by the visual analo-gue scale, roland moris and oswestory disa-bility indices, respectively. Findings: The results of this study showed that only the endurance of lateral trunk fle-xor muscles had correlation with the disab-ility level in these patients, albeit it was not strong (r=0.238, P=0.024). Moreover, flexibility of the hamstring, tensor fascia lata and hip lateral rotator muscles had only strong correlation with pain intensity level (r=0.815, P SP - 10 EP - 20 AU - Zahednezhad, sh AU - salehi, r AU - tajali, sh AU - borji, a AD - KW - disability KW - muscle flexibility and endurance KW - chronic back pain UR - http://sjimu.medilam.ac.ir/article-1-1091-en.html ER -
