Application of handgrip strength test for evaluating mobility in patients with stable chronic obstructive pulmonary disease(COPD) / 中华护理杂志

ABSTRACT

Objective To explore the reliability of handgrip strength test for evaluating mobility in patients with stable chronic obstructive pulmonary disease.Methods Sixty-one COPD patients in stable stage were measured for handgrip strength and 6-minute walking test(6MWT).The receiver operating characteristic curve(ROC) was calculated to determine the best cutoff points of handgrip strength.Results Handgrip strength was (33.72-±7.47) kgf,6MWD was (437.06±97.96) m,handgrip strength was moderately correlated with 6MWD (r=0.404,P=0.001).6MWD≥350 m was used to classify two groups,and there was significant difference between two groups(P＜0.05).Area under the curv e was 0.722,and the best cutoff points was 32.8 kgf.Conclusion Handgrip strength test can be a useful tool to quickly identify mobility in patients with stable COPD.
