作者们想确认乔恩博士, PT, 进行分析, 以确定振动频率的振子在本协议中使用。

st. Scholastica 学院的机构审查委员会批准了这项议定书的编写和测试。
注: 本协议中使用的振动器的制造商规格表明, "高" 的频率为 1100 rpm (183.3 赫兹)。这一频率是通过一个采样的振动数据收集通过一个输入的差分放大器采样在2赫。信号的平均周期为 5.56 x 10-3 s, 相当于 180 Hz。在患有雷诺疾病的个体中, 振动可能会引起雷诺的现象, 在应用场所的临时血管收缩, 可能持续几分钟到几小时, 可能伴有麻木、瘙痒或疼痛。23图 1显示了与本协议中所使用的振动类似的雷诺现象的示例。在参加本议定书之前, 应为雷诺的潜在参与者进行筛选。
1. 本体击倒协议:
<ol><li>收集钢笔, 183 赫兹振动器, 2.5 英寸宽表带和橡皮筋 (请参阅材料表)。</li>
	<li>触及在上肢尺沟内的尺神经进行测试。<ol>
<li>在尺沟的皮肤上放置一个 "x" 标记, 刚好优于肱骨鹰嘴过程与尺骨内侧髁之间的界线。 注意:图 2显示了肘部背部的这个位置。</li>
	</ol>
</li>
	<li>将振动器的头部放置在有标记的位置上, 并将按摩手柄置于头部。<ol>
<li>适用于振动器和参与者手臂的手柄部分周围的宽表带。</li>
		<li>在振子头部和参与者手臂的颈部周围放置橡皮筋, 以保持振动器头部到位, 保持参与者的皮肤和震动头之间的接触, 确保橡皮筋是一个适当的大小, 以保持头部对皮肤, 但不限制移动或循环。</li>
	</ol>
</li>
	<li>请参与者弯曲并伸直肘部。他/她不应该感觉到皮带的干扰。如果他/她报告干扰, 调整皮带和橡皮筋, 以确保行动自由。</li>
	<li>在高上转动振子, 等待2分钟 (基于未发布的数据)。<ol>
<li>进行本体性能测量 (BKT 的 tablet 版本的结果), 在测试期间, 振动器在高处运行。<ol>
<li>进行 BKT。座位参加者在标准高度椅子 (18 寸位子高度), 在标准高度桌 (29 寸高度) 与他们的视觉被遮挡从片剂用窗帘。坐在对面的参与者。</li>
			<li>引导参与者食指, 仅在远端方阵举行, 从线的开始到线 (目标) 的终点, 再回到线的起点。释放参与者的手指, 并指示他们触摸目标。用每根上肢完成20项试验。</li>
			<li>为每个上肢分配参与者的分数作为平均绝对误差 (目标距离) (以厘米为单位)。</li>
		</ol>
</li>
		<li>在消除振动刺激时立即进行心理物理测量 (如视屏)。 注: 在所提出的结果中, 在屏前振动刺激的持续时间为 5 1 分钟。</li>
	</ol>
</li>
</ol>2. 振动检测阈值 (适用于13)
<ol><li>收集128赫兹调谐叉, 秒表, 教科书 (提供一个坚定的, 但符合的表面, 以打击调音叉), 表 (29 英寸高), 标准椅 (18 英寸座椅高度), 屏蔽胶带, 和钢笔。<ol>
<li>在课本上创建一个1½英寸 x 1 ½英寸正方形, 使用掩蔽带作为目标, 以达到一致的敲击音叉。</li>
		<li>使用永久性标记, 将调谐叉的阀杆底部的1毫米着色 (此标记将用于在测试期间对调整叉应用程序的压力进行标准化)。</li>
		<li>把参加者坐在椅子上。请她/他延长前臂的肢体被测试 supinated, 并完全休息在桌子上, 包括肘部。让他们放松四肢。 注: 考官应坐在学员的对面。</li>
	</ol>
</li>
	<li>在皮肤上标记一个点在远端二头肌肌腱, 大约 1 cm 优于肘折痕。<ol>
<li>将书放在最接近参与者的桌子边缘, 在参与者的肘部之间。</li>

	</ol>
</li>
	<li>确保调整叉两端的圆盘在开始前是紧的。如果他们是松散的, 他们将拨浪鼓和减少调谐叉的共振的持续时间, 使测试不可靠。<ol>
<li>在拇指和食指之间松散地握住调谐叉的茎, 并在正方形目标内的书上击打它, 以产生共鸣。<ol>
<li>在撞击后立即, 将调谐叉放在测试位置, 使用足够的压力来压制皮肤, 并在调谐叉上隐藏1毫米波段的视觉。 注意:图 3显示了此协议中使用的远端二头肌肌腱测试位置的调谐叉。</li>
			<li>使用秒表, 量化调整叉放置到参与者的皮肤上的时间, 直到参与者不再感到震动 (说 "现在")。</li>
		</ol>
</li>
		<li>在同一臂上重复两次, 共进行三项试验。<ol>
<li>计算三试验中振动刺激消失的平均时间, 以确定振动检测阈值 (VDT)。</li>

作者没有什么可透露的。

本协议提供了一种在上肢中击倒人体本体的方法。在20健康参与者中, 本体击倒的效果很大, 视屏的心理测量方法反映 Aα传入轴突传输。当 Aα传入放电减少时, 在振动消除后, 可快速测量出该视屏。25此协议对到达目标具有视觉闭塞 (tBKT) 的错误的影响是适度的。这可能反映出, 该议定书只涉及一个单一的振动刺激在肘部, 一个联合在多关节的任务达成。关于其他可用的方法, 如缺血...

在神经控制运动的所有贡献者中, 本体可能是测量得最少的。本体使用专用设备的研究措施, 最近取得了可靠性、有效性和精确性;1,2,3相比之下, 本体的临床措施, 最常见的肢体位置感测试,4有低分辨率, 受到其他感官方式,4 , 并有不良或没有发表的心理测量属性。5需要新的精确、可靠的本体措施来阐明本体控制的外围和中枢机制、3用于临床诊断损伤, 并测量本体训练的结果。2,5,6,7为此, 需要一个简单的、非侵入性的方法来暂时损害或 "击倒" 本体。
本体击倒在健康的人允许研究人员推断本体功能的作用在一个感觉运动的任务, 这是有用的, 以通知发展和验证标准化措施。被击倒的模型有两个主要好处比研究人与损伤的本体。第一个是参与者的可用性;许多研究人员不容易接触到有本体损伤的个体。第二, 与体内本体损伤不同, 击倒模型可能允许控制参与者之间的损伤程度。
目前发布的方法的临时本体击倒的上肢是侵入, 不切实际, 或不舒服的参与者。麻醉注射虽然相对安全, 但需要技术专长, 可能被一些研究参与者认为是侵入性的。缺血性神经阻滞引起的不适和血液测试, 以筛查凝血障碍之前, 他们的应用是实践。8冷冻也会引起不适。冷冻治疗的平均使用时间为20.3 本体5.3 分钟9一旦冷冻被删除, 一个简短的窗口, 以测量本体之前, 温遗骸, 这可能导致不一致的效果关节位置感的冷冻治疗。10高频 (300 Hz) 振动成功地用于减少手指运动检测任务中的本体灵敏度;该机制被报告为小细胞诱导抑制其他振动敏感皮肤受体的输入。11最近, 通过对本体信息进行扭曲, 发现比目鱼肌振动 (80 Hz) 可以降低等距力的生产精度。12然而, 还没有发布一个简单的非侵入性的方法来暂时击倒上肢本体。
该方法的目的是利用高频振动暂时击倒上肢本体在健康的成年人。采用两种测量方法, 即振动检测阈值 (动觉) 和平板版的简单测试 (tBKT) 确定了击倒。视屏是反映 Aα传入轴突传输的敏感性思维的心理测量方法。13本体性能是使用我们实验室正在开发的 tBKT 进行量化的。简要的动觉测试 (BKT) 基于艾尔斯的工作, 14 是一项实验性仪器, 经测试, 但未列入国家卫生研究院工具箱核心电池.15,16 BKT 包括对每个上肢的三个达到的试验。tBKT 包括每上肢20项试验, 目前正在研制, 目的是提高对原试验的心理测量性能。tBKT 包括感觉输入 (对目标的上部肢体的考官教导), 中央处理 (记住目标的空间位置) 和马达输出 (试图找到目标在指南被去除之后), 认为是必要的在措施整体本体性能。17屏和 tBKT 测量, 分别表示体感层次结构中的低和高级别,18 , 因此应提供比单独使用的任何度量值更全面的本体量化。
两种神经机制与高频振动引起的本体灵敏度密切相关。首先, 小体是最常见的与振动检测相关的皮肤 mechanoreceptor。该协议中使用的连续振动可能会根据 Aα和β纤维组与小小体相关的短期适应的神经机制, 提高振动检测的受体调谐阈值。19生理上的结果是, 在视屏测试中, 使用相同强度和频率的振动, 如 128 Hz, 可在更短的时间内感觉到。第二, 据认为, 肌肉纺锤, 通过 Aα传入纤维, 编码肌肉长度不准确后, 高频振动导致失真的本体信息, 证明通过降低准确性在部队再生产,12移动错觉,20,21和减少动觉。22

a simple non-invasive method for temporary knockdown of upper limb proprioception

本体可能是对运动的神经控制的所有贡献者的最不充分的测量。本体的临床诊断需要新的精确、可靠的测量方法, 并测量本体训练的结果。这种简单的, 无创的方法的目的是暂时击倒上肢本体在健康的成年人, 在一定程度上将有助于发展和测试上肢本体措施。击倒模型有两个主要的优势超过研究的人与受损本体: 参与者的可用性和能力, 以控制损害程度, 在参加者。目前发布的方法的临时本体击倒的上肢, 如缺血性神经阻滞和冷冻, 是侵入, 不切实际, 或不舒服的参与者。在这里, 尺沟的振动被用来减少上肢本体。高频振动可抑制小细胞诱导输入, 降低本体视力。采用两种定量方法确定了该协议的振动效果。该方法管理简单, 适合参加者, 实用性强。

Functional Near Infrared Spectroscopy of the Sensory and Motor Brain Regions with Simultaneous Kinematic and EMG Monitoring During Motor Tasks

There are several advantages that functional near-infrared spectroscopy (fNIRS) presents in the study of the neural control of human movement. It is relatively flexible with respect to participant positioning and allows for some head movements during tasks. Additionally, it is inexpensive, light weight, and portable, with very few contraindications to its use. This presents a unique opportunity to study functional brain activity during motor tasks in individuals who are typically developing, as well as those with movement disorders, such as cerebral palsy. An additional consideration when studying movement disorders, however, is the quality of actual movements performed and the potential for additional, unintended movements. Therefore, concurrent monitoring of both blood flow changes in the brain and actual movements of the body during testing is required for appropriate interpretation of fNIRS results. Here, we show a protocol for the combination of fNIRS with muscle and kinematic monitoring during motor tasks. We explore gait, a unilateral multi-joint movement (cycling), and two unilateral single-joint movements (isolated ankle dorsiflexion, and isolated hand squeezing). The techniques presented can be useful in studying both typical and atypical motor control, and can be modified to investigate a broad range of tasks and scientific questions.

Monitoring brain activity during upright motor tasks is of great value when investigating the neural source of movement disorders. Here, we demonstrate a protocol that combines functional near infrared spectroscopy with continuous monitoring of muscle and kinematic activity during 4 types of motor tasks.

The Knob Supination Task: A Semi-automated Method for Assessing Forelimb Function in Rats

Tasks that accurately measure dexterity in animal models are critical to understand hand function. Current rat behavioral tasks that measure dexterity largely use video analysis of reaching or food manipulation. While these tasks are easy to implement and are robust across disease models, they are subjective and laborious for the experimenter. Automating traditional tasks or creating new automated tasks can make the tasks more efficient, objective, and quantitative. Since rats are less dexterous than primates, central nervous system (CNS) injury produces more subtle deficits in dexterity, however, supination is highly affected in rodents and crucial to hand function in primates. Therefore, we designed a semi-automated task that measures forelimb supination in rats. Rats are trained to reach and grasp a knob-shaped manipulandum and turn the manipulandum in supination to receive a reward. Rats can acquire the skill within 20 &plusmn; 5 days. While the early part of training is highly supervised, much of the training is done without direct supervision. The task reliably and reproducibly captures subtle deficits after injury and shows functional recovery that accurately reflects clinical recovery curves. Analysis of data is performed by specialized software through a graphical user interface that is designed to be intuitive. We also give solutions to common problems encountered during training, and show that minor corrections to behavior early in training produce reliable acquisition of supination. Thus, the knob supination task provides efficient and quantitative evaluation of a critical movement for dexterity in rats.

This manuscript describes a semi-automated task that quantifies supination in rats. Rats reach, grasp, and supinate a spherical manipulandum. The rat is rewarded with a pellet if the turn angle exceeds a criterion set by the user. This task increases throughput, sensitivity to injury, and objectivity compared to traditional tasks.

A Standardized Method for Measurement of Elbow Kinesthesia

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.

Here, we present a standardized method for measurement of elbow passive kinesthesia using the threshold to detection of passive movement (TDPM) that is appropriate for a research setting.

Measuring Contralateral Silent Period Induced by Single-Pulse Transcranial Magnetic Stimulation to Investigate M1 Corticospinal Inhibition

Contralateral silent period (cSP) is a period of suppression in the background electrical muscle activity captured by electromyography (EMG) after a motor evoked potential (MEP). To obtain this, an MEP is elicited by a suprathreshold transcranial magnetic stimulation (TMS) pulse delivered to the primary motor cortex (M1) of the target muscle selected, while the participant provides a standardized voluntary target muscle contraction. The cSP is a result of inhibitory mechanisms that occur after the MEP; it provides a broad temporal assessment of spinal inhibition in its initial ~50 ms, and cortical inhibition after. Researchers have tried to better understand the neurobiological mechanism behind the cSP to validate it as a potential diagnostic, surrogate, and predictive biomarker for different neuropsychiatric diseases. Therefore, this article describes a method to measure M1 cSP of lower and upper limbs, including a selection of target muscle, electrode placement, coil positioning, method of measuring voluntary contraction stimulation, intensity setup, and data analysis to obtain a representative result. It has the educational objective of giving a visual guideline in performing a feasible, reliable, and reproducible cSP protocol for lower and upper limbs and discussing practical challenges of this technique.

Contralateral silent period (cSP) assessment is a promising biomarker to index cortical excitability and treatment response. We demonstrate a protocol to assess cSP intended for studying M1 corticospinal inhibition of upper and lower limbs.

Open-Source Real-Time Closed-Loop Electrical Threshold Tracking for Translational Pain Research

Nociceptors are a class of primary afferent neurons that signal potentially harmful noxious stimuli. An increase in nociceptor excitability occurs in acute and chronic pain conditions. This produces abnormal ongoing activity or reduced activation thresholds to noxious stimuli. Identifying the cause of this increased excitability is required for the development and validation of mechanism-based treatments. Single-neuron electrical threshold tracking can quantify nociceptor excitability. Therefore, we have developed an application to allow such measurements and demonstrate its use in humans and rodents. APTrack provides real-time data visualization and action potential identification using a temporal raster plot. Algorithms detect action potentials by threshold crossing and monitor their latency after electrical stimulation. The plugin then modulates the electrical stimulation amplitude using an up-down method to estimate the electrical threshold of the nociceptors. The software was built upon the Open Ephys system (V0.54) and coded in C++ using the JUCE framework. It runs on Windows, Linux, and Mac operating systems. The open-source code is available (<a data-saferedirecturl="https://www.google.com/url?q=https://github.com/Microneurography/APTrack&amp;source=gmail&amp;ust=1680789829274000&amp;usg=AOvVaw0nMk9J_EI2jUn8SlmC5JJm" href="https://github.com/Microneurography/APTrack" target="_blank">https://github.com/Microneurography/APTrack</a>). The electrophysiological recordings were taken from nociceptors in both a mouse skin-nerve preparation using the teased fiber method in the saphenous nerve and in healthy human volunteers using microneurography in the superficial peroneal nerve. Nociceptors were classified by their response to thermal and mechanical stimuli, as well as by monitoring the activity-dependent slowing of the conduction velocity. The software facilitated the experiment by simplifying the action potential identification through the temporal raster plot. We demonstrate real-time closed-loop electrical threshold tracking of single-neuron action potentials during&#160;in vivo&#160;human microneurography, for the first time, and during&#160;ex vivo&#160;mouse electrophysiological recordings of C-fibers and A&#948;-fibers. We establish proof of principle by showing that the electrical threshold of a human heat-sensitive C-fiber nociceptor is reduced by heating the receptive field. This plugin enables the electrical threshold tracking of single-neuron action potentials and allows the quantification of changes in nociceptor excitability.

APTrack is a software plugin developed for the Open Ephys platform that enables real-time data visualization and the closed-loop electrical threshold tracking of neuronal action potentials. We have successfully used this in microneurography for human C-fiber nociceptors and mouse C-fiber and A&#948;-fiber nociceptors.

Using Home-based, Remotely Supervised, Transcranial Direct Current Stimulation for Phantom Limb Pain

Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation technique that uses low-amplitude direct currents to alter cortical excitability. Previous trials have established the safety and tolerability of tDCS, and its potential to mitigate symptoms. However, the effects are cumulative, making it more difficult to have adherence to the treatment since frequent visits to the clinic or outpatient center are required. Moreover, the time needed for transportation to the center and the related expenses limit the accessibility of the treatment for many participants.
Following guidelines for remotely supervised transcranial direct current stimulation (RS-tDCS) implementation, we propose a protocol designed for remotely supervised and home-based participation that uses specific devices and materials modified for patient use, with real-time monitoring by researchers through an encrypted video conferencing platform. We have developed detailed instructional materials and structured training procedures to allow for self- or proxy-administration while supervised remotely in real time. This protocol has a specific design to have a series of checkpoints during training and execution of the visit. This protocol is currently in use in a large pragmatic study of RS-tDCS for phantom limb pain (PLP). In this article, we will discuss the operational challenges of conducting a home-based RS-tDCS session and show methods to enhance its efficacy with supervised sessions.

An Experimental Approach to Induce Trips in Lower-Limb Amputees

Reestablishing balance after a trip is challenging for lower-limb amputees and often results in a fall. The effectiveness of reestablishing balance following a trip depends on factors such as amputation level (transtibial or transfemoral) or which limb is tripped (prosthetic or sound/lead or trailing). Understanding the recovery responses can help identify strategies to avoid a trip becoming a fall and what trip-response functionality could be designed into a prosthesis. This study presents an experimental approach for inducing unexpected trips in individuals with amputation. Tripping was manually triggered by activating an electromagnetic device to raisea polypropylene wire to obstruct (bring to a near halt) theswinging limb during its mid-swing phase. A safety harness attached to a ceiling rail ensured participants did not hit the ground if they failed to reestablish balance following the trip (i.e., it prevented a fall from occurring). One transtibial amputee completed repeated walking trials in which a trip was induced around 1 out of 15 times to avoid it being anticipated. 3D kinematics were determined via two smartphones (60Hz) using the OpenCap software, highlighting that the experimental approach induced meaningful tripping/recovery responses dependent on which limb was tripped (prosthetic or sound). The presented methodology avoids using a rigid obstacle, potentially reducing the risk of injuries, and is inexpensive and easy to set up. Importantly it permits a trip to be unexpectedly introduced during the mid-swing phase of the gait and hence provides an approach for identifying real-world trip recovery responses. When tripping the sound limb, participants could &#39;disentangle&#39; from the trip-wire (post-trip) by plantarflexing the ankle, but such action was not possible when tripping the prosthetic limb.

An experimental approach was developed to induce trips in lower-limb amputees. The goal was to create unexpected trips and induce meaningful tripping/recovery responses. The kinematic data from one transtibial amputee confirmed that such an approach effectively elicits reactive trip recovery responses.

Investigating the Effect of Different Types of Exercise on Upper Limb Functional Recovery in Patients with Right Hemisphere Damage Based on fNIRS

To investigate the effects of functional occupational therapy (FOT) combined with different types of exercise on upper limb motor function recovery and brain function remodeling in patients with right hemisphere damage (RHD) by analyzing functional near-infrared spectroscopy (fNIRS). Patients (n = 32) with RHD at Beijing Bo'ai Hospital were recruited and randomly allocated to receive either FOT combined with passive motion (N=16) or FOT combined with assisted active movement (N=16). The passive motion group (FOT-PM) received functional occupational therapy for 20 min and passive exercise for 10 min in each session, while the assisted active movement group (FOT-AAM) received functional occupational therapy for 20 min and assisted active exercise for 10 min. Both groups received conventional drug therapy and other rehabilitation therapy. Treatment was performed once a day, 5 times a week for 4 weeks. The recovery of motor function and activities of daily living (ADL) was assessed using Fugl-Meyer Assessment upper extremity (FMA-UE) and modified Barthel index (MBI) before and after treatment, and brain activation of the bilateral motor area was analyzed with fNIRS. The findings suggested that FOT combined with AAM was more effective than FOT combined with PM in improving the motor function of RHD patients' upper limbs and fingers, improving their ability to perform activities of daily living, and facilitating brain function remodeling of the motor area.
