To examine intrarater reliability in measurements of active range of motion and passive range of motion of shoulder flexion and abduction when motions are assessed in sitting, as compared with supine.
Thirty adult subjects were measured eight times, in random order, for each of the two shoulder motions: two passive and two active measurements while sitting, and two passive and two active measurements while supine. Data were analyzed to determine intraclass correlation coefficients (ICCs) and paired t values between trials 1 and 2 for measurements in the same position, and between sitting and supine trials for each type of measurement.
Rehabilitation facility and university.
Volunteer sample: 11 rehabilitation inpatients; 19 university students.
ICCs between trials 1 and 2 on comparable measurements in the same position indicated high intrarater reliability for active and passive measurements, regardless of testing position. ICCs between comparable measurements in the two testing positions indicated only a moderate level of agreement. Paired t tests between comparable readings taken in sitting versus supine revealed no significant differences for flexion, but significantly higher measurements of abduction when testing in the supine position.
Measurements in sitting or supine yield similarly high intrarater reliability. Lowered reliability between measurements taken in different positions indicates that test position should be routinely recorded, and repeated clinical measures of individual subjects should be administered in a consistent position.
与仰卧位相比，研究坐位评估肩部前屈和外展的主动活动范围和被动活动范围测量中的评估者内信度。
30名成年受试者对两种肩部动作分别进行8次测量，测量顺序随机：坐位时进行两次被动测量和两次主动测量，仰卧位时同样进行两次被动测量和两次主动测量。分析数据以确定组内相关系数（ICC）以及同一位置测量时第1次和第2次测量之间的配对t值，以及每种测量类型坐位和仰卧位测量之间的配对t值。
康复机构和大学。
志愿者样本：11名康复住院患者；19名大学生。
同一位置可比测量中第1次和第2次测量之间的ICC表明，无论测试位置如何，主动和被动测量的评估者内信度都很高。两个测试位置可比测量之间的ICC仅显示出中等程度的一致性。坐位和仰卧位可比读数之间的配对t检验显示，前屈无显著差异，但仰卧位测试时外展测量值显著更高。
坐位或仰卧位测量产生的评估者内信度同样高。不同位置测量之间信度降低表明应常规记录测试位置，并且应在一致的位置对个体受试者进行重复临床测量。
