Abstract

Objective

To investigate the test-retest reliability and validity of the threshold to detect passive motion (TDPM) and joint position sense (JPS) tests using an image-capture technique compared with the Fugl-Meyer Assessment (FMA) and the Erasmus MC modifications to the Nottingham Sensory Assessment (EmNSA) for evaluating proprioceptive impairment in poststroke patients.

Design

Repeated-measures design.

Setting

A rehabilitation department in a hospital.

Participants

Fifty patients with acute or subacute stroke, with stroke severity ranging from mild to moderate, assessed based on the National Institutes of Health Stroke Scale.

Interventions

Not applicable.

Main Outcome Measures

TDPM, JPS, FMA, and EmNSA assessments were performed twice at a 24-h interval. Reliability was assessed using the intraclass correlation coefficient (ICC) and Bland-Altman analysis, and the minimal detectable change (MDC) was calculated. Convergent and discriminant validity of the proprioceptive measures were evaluated using Spearman’s rank correlation coefficients (r_s).

Results

TDPM demonstrated moderate-to-good reliability (ICC=0.63-0.84; MDC=4.26°-8.34°) without systematic bias. Furthermore, TDPM demonstrated discriminant validity (r_s=−0.40 to 0.11) with JPS, FMA, and EmNSA. Multijoint TDPM demonstrated excellent reliability (ICC=0.91-0.93; MDC=14.57°-15.57°), and convergent validity (r_s=0.80-0.92) was confirmed between TDPM measures corresponding to different movement patterns. FMA and EmNSA demonstrated good-to-excellent reliability (ICC=0.85-0.93; MDC=0.71 score) and convergent validity (r_s=0.72). However, a ceiling effect was observed in 74% of the participants. Conversely, JPS exhibited low reliability (ICC<0.44) and poor validity.

Conclusions

TDPM and multijoint TDPM using the image-capture technique are reliable and useful measures for evaluating proprioception in poststroke patients. Both measures evaluate dimensions distinct from those captured by FMA and EmNSA, indicating the variability of proprioceptive function in poststroke patients.

脑卒中后本体感觉测量的重测信度、收敛效度和判别效度。

目的：探讨采用图像捕获技术的被动运动检测阈值（TDPM）和关节位置感（JPS）测试与fugler - meyer评估（FMA）和Erasmus MC改进的诺丁汉感觉评估（EmNSA）评估脑卒中后本体感觉功能障碍的重测信度和效度。设计：重复测量设计。环境：医院的康复科。参与者：50例急性或亚急性卒中患者，卒中严重程度从轻度到中度不等，根据美国国立卫生研究院卒中量表进行评估。干预措施：不适用。主要结局指标：TDPM、JPS、FMA和EmNSA评估每隔24小时进行两次。采用类内相关系数（ICC）和Bland-Altman分析评估信度，并计算最小可检测变化（MDC）。采用Spearman等级相关系数（rs）评价本体感觉测量的收敛效度和判别效度。结果：TDPM具有中至良好的信度（ICC = 0.63-0.84,MDC = 4.26°-8.34°），无系统偏倚。此外，TDPM与JPS、FMA和EmNSA具有区别效度（rs = -0.40 ~ 0.11）。多关节TDPM表现出优异的信度（ICC = 0.91-0.93,MDC = 14.57°-15.57°），不同运动模式对应的TDPM测量之间的收敛效度（rs = 0.80-0.92）得到证实。FMA和EmNSA具有良至优信度（ICC = 0.85-0.93,MDC = 0.71）和收敛效度（rs = 0.72）。然而，74%的参与者观察到天花板效应。而JPS的信度较低（ICC < 0.44），效度较差。结论：采用图像捕获技术的TDPM和多关节TDPM是评估脑卒中后患者本体感觉的可靠和有用的方法。这两种测量方法评估的维度不同于FMA和EmNSA捕获的维度，表明脑卒中后患者本体感觉功能的可变性。

期刊介绍： The Archives of Physical Medicine and Rehabilitation publishes original, peer-reviewed research and clinical reports on important trends and developments in physical medicine and rehabilitation and related fields. This international journal brings researchers and clinicians authoritative information on the therapeutic utilization of physical, behavioral and pharmaceutical agents in providing comprehensive care for individuals with chronic illness and disabilities. Archives began publication in 1920, publishes monthly, and is the official journal of the American Congress of Rehabilitation Medicine. Its papers are cited more often than any other rehabilitation journal.
