EVALUATOR TRAINING MANIKIN FOR SPASTICITY AND STRENGTH

描述（由申请人提供）：改良Ashworth量表和手动肌肉测试是评估痉挛和力量的重要工具。两者都缺乏准确性和可靠性，但由于其简单性，将继续广泛使用。如果评估人员能够对照“基准”标准进行实践，提供准确和一致的预定义阻力扭矩曲线，则可以提高其可靠性和准确性。这个项目的长期目标是开发一个评估训练人体模型痉挛和力量评估实践。本项目的目的是开发和测试一个人体模型膝关节，用于培训临床医生统一评估膝关节痉挛和力量。 目标1. 开发并测试一种能够在一定运动范围内产生阻力扭矩的人工膝关节。任务1.建立膝关节痉挛强度评估工具（SSKAT）。人工腿和大腿将通过1个旋转自由度铰链（“膝”）关节连接。“膝”关节将能够提供各种计算机控制的阻力矩超过120度的旋转使用磁流变液。任务2：测试SSKAT。将SSKAT连接到KinCom测力计并进行一系列验证测试，以评估SSKAT产生阻力扭矩的准确性和可靠性。 目标2.对SSKAT进行编程，以模拟改良的Ashworth量表和手动肌肉测试水平。任务1.定义和编程阻力扭矩曲线。将确定膝关节的6个阻力曲线（由改良Ashworth量表和3+至5级（5级）手动肌肉测试定义）。将编写计算机软件来描述这些“基准”剖面和控制SSKAT的电阻特性。任务2.“测试SSKAZ。社会技能测验的准确性和可靠性将按照目标1进行评估。在使用Ashworth和手动肌肉测试方面经验丰富的临床医生将评估SSKAT复制电阻曲线的能力。此外，SSKAT的数据将用于检查临床医生的可靠性。 在第二阶段，我们将开发和测试用于踝关节、肘关节、髋关节和腕关节的类似设备，将这些组件集成到训练人体模型中，并考虑针对男性、女性和儿童的不同扭矩曲线。

DESCRIPTION (provided by applicant): The Modified Ashworth scale and manual muscle test are important tools for assessing spasticity and strength. Both lack accuracy and reliability, but given their simplicity, will remain widely used. Their reliability and accuracy could be improved if evaluators could practice against a 'bench mark' standard providing accurate and consistent predefined resistive torque profiles. The long term goal of this project is to develop an evaluator training manikin for spasticity and strength assessment practice. The purpose of this project is to develop and test a manikin knee joint for training clinicians to uniformly assess knee spasticity and strength. Aim 1. Develop and test an artificial knee joint that can produce resistive torques over a range of motion. Task 1."Build the Spasticity Strength Knee Assessment Tool (SSKAT). An artificial leg and thigh will be linked by a 1 rotational degree of freedom hinge ('knee') joint. The 'knee' joint will be able to provide a variety of computer controlled resistive torques over 120 degrees of rotation using magneto-rheological fluids. Task 2: Test the SSKAT. The accuracy and reliability of the SSKAT for producing resistive torques will be evaluated by attaching it to a KinCom dynamometer and performing a series of validation tests. Aim 2. Program the SSKAT to mimic the modified Ashworth scale and manual muscle test levels. Task 1. Define and program resistive torque profiles. The 6 resistive profiles defined by the Modified Ashworth Scale and grades 3+ through 5 (5 grades) of the manual muscle tests will be determined for the knee. Computer software will be written to describe these 'bench mark' profiles and control resistive characteristics of the SSKAT. Task 2." Test the SSKAZ. The accuracy and reliability of the SSKAT will be assessed as in Aim 1. Clinicians experienced in using the Ashworth and manual muscle tests will evaluate the ability of the SSKAT to replicate resistive profiles. In addition, the data from the SSKAT will be used to examine clinician reliability. In Phase II, we will develop and test similar devices for the ankle, elbow, hip, and wrist, integrate the components into a training manikin, and consider different torque profiles for men, women, and children.
