五次坐立试验在慢性阻塞性肺疾病患者下肢功能评估中的初步应用

The preliminary application of five repetition sit-to-stand test for evaluating lower limb function in the patients with chronic obstructive pulmonary disease

目的 探讨5次坐立试验(FTSST)应用于慢性阻塞性肺疾病(COPD)患者下肢功能评估的有效性.方法 对61例COPD患者进行FTSST、下肢等速肌力测试、6 min步行试验的评价,分析FTSST时间与肌力、6min步行试验距离(6MWD)的相关性.结果 FTSST时间为(7.86±2.21)s,伸肌峰力矩为(67.58±24.83) Nm,伸肌相对峰力矩为0.95(0.46) Nm/kg,6MWD为(444.05±112.53) m;FTSST时间与伸肌峰力矩、伸肌相对峰力矩、6MWD、合并症种类相关(r=-0.303、-0.393、-0.428,F=2.813,P＜0.05);以FTSST时间为因变量,进行多元线性回归分析,进入方程的变量是6MWD、合并症种类.结论 FTSST可用于COPD患者下肢功能的快速评估,且FTSST时间越长,下肢功能越差;护理人员应重视COPD患者的下肢功能,了解患者的合并症种类,利用FTSST评估下肢功能.

Objective To determine the value of five repetition sit-to-stand test (FTSST) to evaluate lower limb function in the patients with chronic obstructive pulmonary disease (COPD).Methods Sixty-one patients with COPD were tested for FTSST,isokinetic testing muscle strength for lower limb,6-minute walking test.The relationship between FTSST time and muscle strength,6-minute walking test distance (6MWD) were analyzed.Results FTSST time was (7.86±2.21) s,extensor peak torque was (67.58± 24.83) Nm,extensor relative peak torque was 0.95(0.46) Nm/kg,6MWD was (444.05±112.53) m.FTSST time related to extensor peak torque,extensor relative peak torque,6MWD and types of complication,correlation coefficient values were-0.303,-0.393,-0.428,F =2.813,P ＜ 0.05.Multivariate linear regression analysis showed that when the dependent variable was FTSST time,the variables of the equation were 6MWD and types of complication.Conclusions FTSST can be used for the rapid evaluation of lower extremity function in patients with COPD.The lower limb function gets worse,the FTSST time will be longer.Nursing staff should pay more attention to the lower limb function of patients with COPD,along with complications,using FTSST to evaluate lower extremity function.
