Locomotive Syndrome is associated with chronic pain and poor quality of life in Brazilian oldest old: LOCOMOV Project

BackgroundIn 2007, the Japanese Orthopedic Association established the term “Locomotive Syndrome” (LS) for the concept of locomotor organ dysfunction with potential loss of independence. The purpose of this study was to identify characteristics of LS and establish a diagnostic cut-off for the Geriatric Locomotive Function Scale (GLFS 25-p) for the Brazilian population.MethodsA cross-sectional observational study of the LOCOMOV Project cohort of independent outpatients aged ≥80 years was conducted. Questionnaires on functional status in Basic and Instrumental Activities of Daily Living (Katz and Lawton, respectively) and quality of life (WHOQOL-Bref) were applied, together with the Geriatric Locomotive Function Scale (GLFS 25-p) to identify individuals with LS. Mobility was assessed using the five-times sit-to-stand test, 4-m gait speed, two-step test, one-leg standing time with eyes open and hand-grip test. The data were analyzed using Student's t-test, the Chi–Square test, and multiple logistic regression (stepwise). The significance level was set at 0.05 (5%).ResultsA sample of 102 individuals with mean age of 87.3 (±4.2) years and predominantly female (73.5%) was assessed. We determined a cut-off score of 19 (sensitivity of 0.86 and specificity of 0.67) for diagnosis of LS, as assessed by the GLFS 25-p, and a high prevalence (55%) of the syndrome was found in the sample. In the multiple regression analysis, LS was directly associated with chronic pain (OR 22.24, 95%CI 3.13–157.87), use of a walking device (OR 17.121, 95%CI 1.94–150.49), and inversely associated with gait speed ≥0.8 m/s (OR 0.42, 95%CI 0.006–0.278), perception of good health (OR 0.153, 95%CI 0.029–0.799) and male gender (OR 0.086, 95%CI 0.0105–0.714).ConclusionThe LS in the oldest old proved a very common condition in this survey, especially in women, and was strongly associated with chronic pain, worse performance on physical tests and poor quality of life.
