Proprioception is an important component of controlled movement. The threshold to detection of passive movement (TDPM) is a commonly used method for quantifying the proprioceptive submodality of kinesthesia in research settings. The TDPM paradigm has been found to be valid and reliable; however, the equipment and methods used for TDPM vary between studies. In particular, the research laboratory apparatuses for producing passive movement of an extremity are often custom designed by individual laboratories or inaccessible due to high cost. There is a need for a standardized, valid, and reliable method for measuring TDPM using readily available equipment. The purpose of this protocol is to provide a standardized method for measurement of TDPM at the elbow that is economical, easy to administer, and that produces quantitative results for measurement purposes in research-based settings. This method was tested on 20 healthy adults without neurological impairment, and eight adults with chronic stroke. The results obtained suggest this method is a reliable way to quantify elbow TDPM in healthy adults, and provides initial support for validity. Researchers seeking a balance between equipment affordability and measurement precision are most likely to find this protocol of benefit.
本体感觉是受控运动的一个重要组成部分。被动运动检测阈值（TDPM）是研究环境中量化动觉本体感觉亚模态的常用方法。已发现TDPM范式是有效且可靠的；然而，不同研究中用于TDPM的设备和方法各不相同。特别是，用于产生肢体被动运动的研究实验室仪器通常由各个实验室定制设计，或者由于成本高昂而难以获得。需要一种使用现成设备测量TDPM的标准化、有效且可靠的方法。本方案的目的是提供一种在肘部测量TDPM的标准化方法，该方法经济、易于实施，并能在基于研究的环境中产生用于测量目的的定量结果。该方法在20名无神经功能障碍的健康成年人和8名慢性中风成年人身上进行了测试。获得的结果表明，该方法是量化健康成年人肘部TDPM的可靠方法，并为有效性提供了初步支持。寻求设备可承受性和测量精度之间平衡的研究人员最有可能发现本方案的益处。
