The effect of the abdominal muscles on kyphosis in elderly patients

Abstract

function and cough function information from their clinical records. We statistically analyzed comparison between groups, correlation and multiple regression analysis as a purpose variablewithRPCFby theSPSS (ver15.0J) forWindows (All level of significance is p< 0.05). We also calculated the cut-off value from the ROC curve demand sensitivity and specificity from the relationship of RPCF and VPCF and the presence or absence of aspiration risk by RSST. Results: R2 group were significantly lower compared to the R3 group in VPCF (R2 group1.2± 0.9 L/min, R3 group 2.7± 1.0 L/min) and RPCF (R2 group 2.3± 0.8 L/min, R3 group 3.0± 0.8 L/min) (p< 0.001). In addition, the paralyzed side function, cognitive function, non-paralyzed side function, activities of daily living, respiratory muscle strength, and swallowing function were also significantly lower in the R2group comparedwithR3group (p< 0.05–0.001). The total VPCF (1.9± 1.2 L/min) showed significantly lower value compared to RPCF (2.6± 0.9 L/min) in 42 cases, Between RPCF and VPCF it showed significant positive correlation (r= 0.80, p< 0.001). Cut-off value of VPCF was 2.35 L/min (90% sensitivity, 67% specificity, p< 0.01, AUC= 0.87, 95% confidence interval 0.76–0.98), cut-off value of RPCF was also 2.6 L/min (sensitivity 71%, 81% specificity, p< 0.01, AUC= 0.74, 95% confidence interval 0.59–0.90). Conclusion(s): In this study, both RPCF and VPCF have been shown to be useful as an evaluation indicating the risk of aspiration by using RSST in elderly patients with cerebrovascular disorders. Implications: This study will contribute to an evaluation and prevention of elderly patients with cerebrovascular disorder with the aspiration risk.
