Introduction: Low back pain is one of the most common and important public health problems of the current societies and it is the major cause of functional limitation for people under the age of 45. 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<0.01) meaning that muscle shortness have profound effects on pain intensity. Discussion & Conclusion: These findings could be important in the design of reha-bilitation programs for people with nons-pecific chronic low back pain. This means that physiotherapy treatments should be directed towards impairments that have stronger correlation with pain, functional limitations and disability as these are the major complains of these patients.
