The purpose of this study was to examine the intra-tester and inter-tester reliability of chest expansion (CE) using a tape measure, in people with ankylosing spondylitis (AS) and healthy subjects. Twenty-two subjects with AS with a mean age of 41.4 years and 25 healthy subjects with a mean age of 41.0 years were tested in two arm positions: hands on head and arms at the sides, the tape measure being placed at the level of xiphisternum. There were three testers for subjects with AS and two testers for healthy subjects. Three trials in both arm positions were recorded by each tester on two separate occasions which were 10 minutes apart. Results showed intraclass correlation coefficients (ICC) for intra-tester reliability good (0.85 to 0.97) across the occasions. Intraclass correlation coefficients for inter-tester reliability were also very good (0.93 to 0.97). As reliability is good it is suggested that CE can be used for monitoring disease progression and efficacy of intervention with confidence within tester and between testers.
本研究旨在检测使用卷尺测量强直性脊柱炎（AS）患者和健康受试者胸廓扩张度（CE）时，测试者内部及测试者之间的可靠性。22名平均年龄41.4岁的AS患者和25名平均年龄41.0岁的健康受试者在两种手臂位置进行测试：双手放在头部和双臂垂于身体两侧，卷尺置于剑突水平。AS患者有三名测试者，健康受试者有两名测试者。每位测试者在两个不同时间（间隔10分钟）记录两种手臂位置下的三次测量结果。结果显示，测试者内部可靠性的组内相关系数（ICC）在各测量中良好（0.85至0.97）。测试者之间可靠性的组内相关系数也非常好（0.93至0.97）。由于可靠性良好，建议CE可用于自信地监测疾病进展和干预效果，无论是在测试者内部还是测试者之间。
