Fear of falling and history of falls are frequent situations in older adults, which can be aggravated by sedentary behavior (SB). The objective was to establish SB cutoff values which discriminate falls and fear of falling in older adults and verify the association between these conditions. This was a cross-sectional study including 308 community-dwelling older adults. The SB was assessed by International Physical Activity Questionnaire. The outcomes were history of falling in the last 12 months and fear of falling (higher or equal than 23 points in Falls Efficacy Scale International—Brazil). The cutoff points found were >4.14 (area under curve = 0.60, 95% confidence intervals [CIs] [0.54, 0.65]) and >3.90 hr per day (area under curve = 0.59, 95% CI [0.53, 0.64]) for fear of falling and history of falls, respectively. Older adults with SB had 1.71 (95% CI [1.03, 2.84]) and 1.75 (95% CI [1.06, 2.89]) greater odds of having greater fear of falling and suffering falls, respectively. [ABSTRACT FROM AUTHOR]

Background and objective: Individuals after stroke are likely to deal with the possible development of sarcopenia and reduced physical activity levels. The purpose of this study was to compare sarcopenia of individuals with chronic stroke who were stratified according to their physical activity levels, and to evaluate the relationship between sarcopenia and physical activity levels. Materials and Methods: This cross‐sectional study was conducted with individuals after chronic stroke recruited from the general community. Individuals were submitted to sarcopenia screening (SARC‐F questionnaire) and assessment of physical activity levels (Human Activity Profile questionnaire) to classify the individuals as impaired, moderately active, and active according to their Adjusted Activity Status (AAS). ANOVA was used to investigate the sarcopenia between groups and Pearson's coefficient to investigate the association among variables. Results: Fifty‐four individuals with a mean age of 56 ± 17.4 years were included. Twenty‐one percent of the individuals were screened for sarcopenia. Inactive individuals had higher mean scores in the SARC‐F (3.6 ± 2.1 points), whereas moderately active and active individuals presented lower mean scores in the same questionnaire, being 1.2 ± 1.1 points and 0.5 ± 0.7 points, respectively. A statistically significant inverse and high association was found between sarcopenia and physical activity levels (r = −0.716; p < 0.01). Conclusion: Sarcopenia was found to be higher in individuals after chronic stroke with lower physical activity levels considered inactive when compared to individuals with higher physical activity levels. Furthermore, there was an inverse relationship between sarcopenia and physical activity level in stroke survivors. [ABSTRACT FROM AUTHOR]

Study Design: Cross-sectional, ancillary study of an international multicenter epidemiological study.Objective: To investigate the relationship of the anterior trunk mobility with self-report and physical performance measures in elderly women with acute low back pain (LBP).Summary Of Background Data: LBP is one of the most prevalent pain complaints in the elderly population. It is postulated that the increased range of motion of limited joints of the trunk may improve LBP and functionality of patients. Recent studies have, however, questioned the association between trunk range of motion and the functional status.Methods: The present study included a convenience sample of elderly women from the community aged 60 years and older who presented with a new (acute) episode of LBP. Volunteers with severe diseases and visual, hearing and mobility losses, or cognitive impairment were excluded. Trunk mobility was assessed by the fingertip-to-floor test. Functionality was assessed by the Roland-Morris Questionnaire (RMQ) and gait speed test. Statistical analysis was performed by using hierarchical linear regression model.Results: Data from 459 elderly women, mean age of 69.0 (6.1) years old, were used to describe this report. The additional predictive value for the inclusion of independent variable trunk mobility was only 4.4% in the RMQ score and 1.5% in the gait speed test, respectively. A reduced hierarchical linear regression model showed that the significant predictors for RMQ and gait speed test were body mass index, pain intensity, and trunk mobility.Conclusion: This was the first study to investigate the relationship between trunk mobility and functionality in elderly women with acute LBP. The results suggest that these clinical parameters are independent from each other.Level Of Evidence: N/A. [ABSTRACT FROM AUTHOR]

Objective: The aims of this study were to determine the course of plasma levels of inflammatory mediators (interleukin 6 [IL-6], tumor necrosis factor α [TNF-α], soluble TNF receptor 1 [sTNF-R1]) and the severity of low-back pain (LBP) over 6 to 12 months after an acute episode of LBP in elderly women and to establish an association between inflammatory mediators and LBP recovery. Design: This was a longitudinal study of a subsample (155 elderly women with acute LBP, aged ≥65 years) of the international Back Complaints in the Elders cohort study. Plasma levels of IL-6, TNF-α, and sTNF-R1 were measured using enzyme-linked immunosorbent assays and pain severity using the numerical pain scale. Results: There was a decrease in the severity of LBP (P = 0.033) and in the levels of IL-6 and TNF-α (P < 0.001) and an increase in sTNF-R1 (P < 0.001) in the first year after an acute episode of LBP. The probability of occurrence of pain relief at the 12-month follow-up was 2.22 times higher in elderly women who had low levels of IL-6 (<1.58 pg/mL) at baseline. Conclusions: Our findings showed a relationship between inflammation and LBP by establishing that low IL-6 plasma levels preceded outcome (LBP recovery), supporting the concept that proinflammatory cytokines promote pain.
