ABSTRACT
Among the types of chronic musculoskeletal pain, low back pain is one of the most common symptoms, with lifetime prevalence of 84%. Despite its high incidence, its causes and risk factors are not well understood. The objective of this study was: (1) compare the flexibility and characteristics of static posture between individuals with and without chronic non-specific low back pain; and (2) check for any relationship between the presence and intensity of chronic non-specific low back pain and disability, flexibility and static posture characteristics. A total of 104 adult subjects, aged 18 to 60 years, participated in the study. The sample was divided into two groups: patients with chronic non-specific low back pain (GWP - group with pain; n=52) and patients without low back pain (GWOP - group without pain; n=52). Data collection consisted of four steps: (1) anamnesis; (2) static postural assessment by photogrammetry using the Digital Image-based Postural Assessment (DIPA©) software protocol; (3) special body flexibility tests; and (4) application of the Oswestry Disability Index (ODI) questionnaire. Pain intensity showed a significant correlation with the disability index (r=0.42; p=0.00) and Wells flexibility test (r=-0.32; p=0.02). No correlation was observed between the presence of pain and static posture and flexibility, and no difference was observed between the groups. Individuals with greater intensity of chronic non-specific low back pain presented greater disability and lower scores in the Wells flexibility test.
