Abstract

Background

Accurate proprioception in the thumb carpometacarpal (CMC) joint is necessary during activities such as performing fine manipulative tasks, such as coin handling, opening doors, using keys, and pressing control buttons.

Purpose

The primary aim of the present study was to examine the test-retest reliability of CMC joint position sense (JPS) in healthy subjects. The secondary aim was to determine the most reliable JPS testing position for the thumb CMC joint.

Study Design

This was a cross-sectional study of a convenience sample of healthy adults.

Methods

Three thumb positions (20°, 30°, and 40° of thumb abduction) were measured twice on the same day by a single rater using a universal goniometer. The absolute error in degrees between each position and reposition was calculated. The intraclass correlation coefficient (2,1) was calculated for relative reliability. The standard error of the measurement was calculated.

Results

Sixty-four healthy adults (mean age 27.8 years, standard deviation = 8.7) were assessed. The intraclass correlation coefficients were poor (−0.08 to 0.22), and the standard error of the measurement was 1.4° for all positions.

Conclusions

The joint position reproduction test for JPS using goniometry demonstrated poor test-retest reliability and acceptable measurement error in healthy adults.

在健康成年人中测试腕掌关节位置感的再测试可靠性。

背景：在进行精细的操作任务（如硬币处理、开门、使用钥匙和按下控制按钮）时，拇指腕掌关节（CMC）的准确本体感觉是必要的。目的：本研究的主要目的是检验健康受试者CMC关节位置感（JPS）的重测可靠性。次要目的是确定拇指CMC关节最可靠的JPS测试位置。研究设计：这是一项以健康成年人为方便样本的横断面研究。方法：同一天用一台万能角度计测量三个拇指位置（拇指外展20°、30°和40°）两次。计算每个位置和重新定位之间的绝对误差（以度为单位）。计算组内相关系数（2,1）的相对可靠性。计算了测量的标准误差。结果：64名健康成年人（平均年龄27.8岁，标准差=8.7）接受了评估。组内相关系数较差（-0.08至0.22），所有位置的测量标准误差为1.4°。结论：在健康成年人中，使用测角术进行JPS的联合位置再现测试显示出较差的重测可靠性和可接受的测量误差。
