Abstract

Abstract Study aim: Evaluation of dynamic balance is inferred to be compulsory for fall prevention in the elderly. Therefore, this study aimed to develop a modified digital functional reach test device using an ultrasonic sensor for balance assessment and to test validity and reliability of the newly developed tool to qualify psychometric properties. Material and methods: This study was a cross-sectional study of a convenient sample including 50 participants both males and females. Mean age of the participants was 51.20 ± 19.30 years. Reliability of the newly developed device was analysed using the intraclass correlation coefficient (ICC) and standard error of measurement (SEM). The criterion validity was also investigated using a yardstick mounted on the wall at a level of shoulder together with the MaxTraq® 2D motion analysis software. The modified digital functional reach test device using an ultrasonic sensor was correlated with the conventional FRT and the MaxTraq® 2D motion analysis. Results: The results presented that test-retest reliability of the modified digital functional reach test device was good reliability (ICC = 0.76) and low standard error of measurement (1.41) was found for test-retest reliability. The degree of agreement between the modified device, the conventional FRT, and the MaxTraq® 2D motion analysis was high (r = 0.71 and 0.77 respectively). Conclusions: The findings suggested that the modified digital functional reach test device using an ultrasonic sensor was a valid and reliable instrument for fall risk screening towards functional reach distance.

一种利用超声传感器进行平衡评估的改进数字式功能到达测试装置:效度和信度测试

摘要研究目的:推测动态平衡评估是老年人预防跌倒的必要条件。因此，本研究旨在利用超声传感器开发一种改进的数字功能到达测试装置，用于平衡评估，并测试新开发的工具的有效性和可靠性，以评估心理测量特性。材料和方法:本研究为横断面研究，选取方便的样本，包括50名男女参与者。参与者平均年龄51.20±19.30岁。采用类内相关系数(ICC)和测量标准误差(SEM)对该装置的可靠性进行了分析。还使用安装在肩部水平墙上的标尺以及MaxTraq®2D运动分析软件来调查标准的有效性。使用超声波传感器的改进数字功能到达测试装置与传统的FRT和MaxTraq®2D运动分析相关联。结果:改进后的数字式功能到达测试装置的重测信度较好(ICC = 0.76)，重测信度的测量标准误差较低(1.41)。改良装置、传统FRT和MaxTraq®2D运动分析之间的一致性很高(r分别为0.71和0.77)。结论:改进的超声传感器数字式功能够远测试装置是一种有效、可靠的功能够远风险筛查仪器。
