주관절 가동범위 측정법에 대한 동시타당도와 신뢰도

Abstract

The purpose of this study was to assess the concurrent validity and reliability ofgoniometric measurement of joint motion. Subjects were 40 healthy universitystudents. Measurements were performed by 4 inexperienced physical therapy students. Four different instruments were used and three readings were taken with eachinstrument in random order making a total of 12 readings for flexion of the rightelbow of each subject. Goniometers used were 1. uoiversal 2. fluid-basedgoniometer/inclinometer 3. digital LCD goniometer 4. electronic goniometer/torsiometer. The results were as follows: Concurrent validity was highest (r= .94) with theuniversal and digital LCD tools. Interrater reliability (Pearson Product MomentCorrelabon) was good for each tool. Interrater reliability calculated by ICC(2,1) washighest (.96) with the tensiometer and lowest (.78) with the digital LCD goniometer. Intrarater reliability calculated by ICC was excellent (≥.90 ) for all instruments. Theseresults show that concurrent validity, intrarater and interrater reliability are verygood in the used of all four types of goniometers/inclinometer/tensiometer, even withinexperienced raters. These results confirm the almost universal reliance on hand heldgoniometers for joint measurement by physical therapists as being a reliable practice. Further research should be done clinically with actual patients.
