The non-specific chronic low back pain is a musculoskeletal condition responsible for high costs to health care. The patients' physical activities level evaluation is often made by Physical Activity Questionnaire (Subjective measures). Although these evaluation tools are reliable and valid when applied to the population in general, it is not known precisely if these questionnaires behave the same way when applied to non-specific chronic low back pain population. Thus, the studies goal will be (I) evaluate the psychometric properties of reproducibility test-retest of the International Physical Activity Questionnaire - IPAQ long version and the Baecke Physical Activity Questionnaire - BPAQ on low back pain patients and (II) evaluate the competitor type of long IPAQ and BPAQ validity compared to the physical activities accelerometers (objective measure). Therefore, based on this study it will be possible to clarify whether the evaluation tool is reproducible and valid to non-specific low back pain population.
