STUDY DESIGN
Clinical measurement, cross sectional.
PURPOSE
To introduce a new measurement device, the Pollexograph, to easily measure palmar thumb abduction, and to compare its reliability with conventional goniometry.
METHODS
Fourteen hand therapists measured palmar abduction of the same healthy subject with the Pollexograph and a conventional goniometer. In addition, intrarater reliability of the Pollexograph was studied in 21 patients with a hypoplastic thumb.
RESULTS
Variance between measurements of the same subject measured by the hand therapist was 2-6 times smaller with the Pollexograph compared to conventional goniometry. Pollexograph intrarater reliability in hypoplastic thumb patients was excellent (intraclass correlation coefficient (ICC)=0.98-0.99).
CONCLUSIONS
A new tool to measure palmar abduction in clinical care, the Pollexograph, has been introduced. The Pollexograph reduces variability between raters when measuring the same subject compared with conventional goniometry and excellent measurement reliability in hypoplastic thumb patients.
LEVEL OF EVIDENCE
Not applicable.
研究设计
临床测量，横断面研究。
目的
介绍一种新的测量设备——拇指外展测量仪，以方便测量拇指掌侧外展，并将其可靠性与传统测角法进行比较。
方法
14名手部治疗师使用拇指外展测量仪和传统测角仪对同一健康受试者的拇指掌侧外展进行测量。此外，还对21名拇指发育不全患者进行了拇指外展测量仪的测量者内可靠性研究。
结果
与传统测角法相比，手部治疗师使用拇指外展测量仪对同一受试者进行测量时，测量结果的差异小2至6倍。拇指外展测量仪在拇指发育不全患者中的测量者内可靠性极佳（组内相关系数（ICC）=0.98 - 0.99）。
结论
已引入一种用于临床护理中测量拇指掌侧外展的新工具——拇指外展测量仪。与传统测角法相比，拇指外展测量仪在测量同一受试者时可减少测量者之间的变异性，并且在拇指发育不全患者中具有出色的测量可靠性。
证据水平
