Background

In patients who have suffered a stroke, the measurement of center of pressure excursion in all directions including oblique direction, anterior-medial, anterior-lateral, posterior-medial, and posterior-lateral side is important for determining balance instability but no research has been reported.

Objectives

This study investigated weight shift in all directions to determine balance instability in stroke patients, including the oblique direction, using the multi-directional functional reach test.

Methods

Eleven subjects participated. Multi-directional functional reach test consisted of moving the unaffected arm as far as possible in 8 directions. The directions were as follows; anterior, middle of anterior and lateral in unaffected side, lateral in unaffected side, and middle of the posterior and lateral in unaffected side, posterior, middle of posterior and lateral in affected side, lateral in affected side, middle of anterior and lateral in affected side.

Results

Movement was the lowest in the affected posterior-lateral side, followed by affected posterior, affected anterior-lateral, non-affected posterior lateral, affected lateral, non-affected lateral, non-affected anterior-lateral and anterior side (p < 0.05).

Conclusion

Center of pressure excursion of the affected posterior-lateral side was the most challenging for stroke patients and their reach was lowest from posterior, to lateral, and anterior directions, whilst patients could move less on the affected side compared with the non-affected side.

Objectives

The purpose of this study was to evaluate hypertension with simple anthropometry data related to obesity in Korean adults and identify whether age specific waist circumference (WC) may be a useful screening tool for determining hypertension.

Methods

Subjects (n = 571) were classified into 3 groups by age; young (18–39 years), middle aged (40–64 years), and old aged (≥ 65 years). Correlations between demographic and anthropometric parameters and hypertension were performed using Spearman correlation analysis. Logistic regression analysis and ROC (receiver operating characteristics) curves were also analyzed for correlations with hypertension.

Results

Spearman correlation analyses, age, gender, WC, and body mass index were positively correlated with hypertension. When logistic regression analysis was performed, increased age and increased WC was associated with a higher incidence of hypertension, although gender and body mass index were not significantly related to hypertension. In ROC analysis of WC for hypertension demonstrated that patients in the old age group showed higher WC cutoff value than patients in the young and middle aged groups.

Conclusion

The findings of this study demonstrate that WC may be a useful predictor of hypertension incidence among demographic and anthropometric factors in Korean adults. In addition, WC in the young population was more sensitive to the incidence of hypertension than in the elderly population.
