Abstract

BACKGROUND

Measurement of thoracic excursion (TEM) during maximal ventilation is part of the physiotherapy assessment in children with cystic fibrosis (CF).

OBJECTIVES

The purpose of our study was to examine the reliability of TEM and its relation with pulmonary function.

METHODS

Thoracic excursions were measured using a measuring tape. Thirty children participated in an intra-observer and inter-observer reliability study. Reliability was determined by calculating the typical error in repeated measurement, limits of agreement and correlation coefficients. Cross-sectional data from the annual check-ups were used to measure the relation between TEM and pulmonary function.

RESULTS

In the intra-observer reliability study the typical error was 0.31 cm, the limits of agreement were +/-0.86 cm. Pearson's r and ICC were 0.96 and 0.95, respectively. In the inter-observer reliability study these values were 0.56 cm, +/-1.55 cm, 0.85 and 0.85, respectively. TEM correlated significantly with height (0.31, P<0.001), FVC (0.44, P<0.001), FEV1 (0.41, P<0.001) and TLC (0.19, P<0.05), and there was a significant inverse correlation with RV%TLC (-0.45, P<0.001).

CONCLUSIONS

TEM is a reliable assessment tool. Thoracic excursion is significantly, although moderately correlated with pulmonary function.

摘要

背景

最大通气量时胸廓活动度（TEM）的测量是囊性纤维化（CF）患儿物理治疗评估的一部分。

目的

我们研究的目的是检验TEM的可靠性及其与肺功能的关系。

方法

使用卷尺测量胸廓活动度。30名儿童参与了观察者内和观察者间可靠性研究。通过计算重复测量的典型误差、一致性界限和相关系数来确定可靠性。利用年度体检的横断面数据来测量TEM与肺功能之间的关系。

结果

在观察者内可靠性研究中，典型误差为0.31cm，一致性界限为±0.86cm。Pearson相关系数r和组内相关系数（ICC）分别为0.96和0.95。在观察者间可靠性研究中，这些值分别为0.56cm、±1.55cm、0.85和0.85。TEM与身高（0.31，P<0.001）、用力肺活量（FVC，0.44，P<0.001）、第1秒用力呼气容积（FEV1，0.41，P<0.001）和肺总量（TLC，0.19，P<0.05）显著相关，与残气量占肺总量百分比（RV%TLC，-0.45，P<0.001）呈显著负相关。
