Proprioception may be the least well measured of all contributors to the neural control of movement. New precise, reliable measures of proprioception are needed for clinical diagnosis of impairment, and to measure outcomes of proprioceptive training. The purpose of this simple, non-invasive method is to temporarily knockdown upper limb proprioception in healthy adults, to an extent that would be useful in the development and testing of upper limb proprioception measures. Knockdown models have two main advantages over studying humans with impaired proprioception: participant availability and the ability to control the extent of impairment across participants. Current published methods of temporary proprioception knockdown of the upper limb, such as ischemic nerve blocks and cryotherapy, are invasive, impractical, or uncomfortable for the participant. Here, vibration over the ulnar groove was used to reduce upper limb proprioception. High frequency vibration may reduce proprioceptive acuity by inhibiting pacinian corpuscle-induced input. The effect of vibration used in this protocol was confirmed using two quantitative measures. This method was simple to administer, comfortable for participants, and practical.
本体感觉可能是对运动神经控制的所有因素中测量最不完善的。临床诊断功能障碍以及测量本体感觉训练的结果需要新的精确、可靠的本体感觉测量方法。这种简单、非侵入性方法的目的是在健康成年人中暂时降低上肢本体感觉，降低程度要达到对上肢本体感觉测量方法的开发和测试有用的程度。与研究本体感觉受损的人类相比，敲低模型有两个主要优点：参与者的可获得性以及控制参与者之间损伤程度的能力。目前已发表的暂时降低上肢本体感觉的方法，如缺血性神经阻滞和冷冻疗法，对参与者来说是侵入性的、不实用的或不舒服的。在这里，通过在尺神经沟上振动来降低上肢本体感觉。高频振动可能通过抑制环层小体诱导的输入来降低本体感觉敏锐度。本方案中使用的振动效果通过两种定量测量方法得到了证实。这种方法实施简单，参与者感觉舒适，且切实可行。
