For every 10-point increase in SFM score, the odds of future VCF decreases by 18 % at 1 year and 27 % at 3 years after adjusting for known covariates. The SFM may aid in the identification of modifiable functional risk factors for VCF.
Adults with higher SFM scores ("safer motion" during performance of everyday tasks) were less likely to have a history of fracture or injurious fall. Further study is warranted to evaluate the predictive value of this tool.
Introduction. This study determined the agreement between measures of standing posture in individuals at risk of osteoporotic fracture obtained using the IONmed mobile phone application and a digital inclinometer. Methods. One experienced rater assessed 20 adults, aged 55-88 years, attending an outpatient osteoporosis clinic. A standardized protocol was duplicated to acquire a single measure of spine curvature (lumbosacral angle, lordosis, kyphosis) using the IONmed mobile phone application and a digital inclinometer. Interdevice agreement was determined using the intraclass correlation coefficient (ICC) with 95% confidence intervals (CI) and standard error of the measurement (SEM) with 95% CI and Bland-Altman plots. Results. ICC (95% CI) for lumbosacral angle, lordosis, and kyphosis is 0.97 (0.92, 0.99), 0.97 (0.92, 0.99), and 0.99 (0.98, 1.0), respectively. SEM (95% CI) for lumbosacral angle, lordosis, and kyphosis is 0.99 ∘ (0.75, 1.44), 1.33 ∘ (1.01, 1.94), and 1.23 ∘ (0.94, 1.80), respectively. Measurement bias is small. Conclusions. In our sample, the IONmed mobile phone application provides measures highly consistent with the digital inclinometer measures of standing posture. This method offers clinicians a quick, convenient way of identifying alterations in spine alignment which require followup and remediation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
