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.

描述（由申请人提供）：改良阿什沃斯量表和徒手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，但鉴于其简单性，仍将被广泛使用。如果评估人员能够根据提供准确且一致的预定义阻性扭矩曲线的“基准”标准进行练习，则可以提高其可靠性和准确性。该项目的长期目标是开发用于痉挛和力量评估实践的评估训练模型。该项目的目的是开发和测试模拟膝关节，以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范围的运动范围内产生阻力矩的人工膝关节。任务 1.“构建痉挛强度膝关节评估工具 (SSKAT)。假腿和大腿将通过 1 个旋转自由度铰链（‘膝’）关节连接。‘膝’关节将能够使用磁流变液提供超过 120 度旋转的各种计算机控制的阻力矩。任务 2：测试 SSKAT。SSKAT 用于生产的准确性和可靠性 将通过将其连接到 KinCom 测力计并执行一系列验证测试来评估阻力矩。 目标 2. 对 SSKAT 进行编程以模仿修改后的 Ashworth 量表和手动肌肉测试水平。任务 1. 定义并编程阻性扭矩曲线。将针对膝盖确定由改良阿什沃斯量表定义的 6 个电阻曲线以及手动肌肉测试的 3+ 级至 5 级（5 个等级）。将编写计算机软件来描述这些“基准”配置文件并控制 SSKAT 的电阻特性。任务 2." 测试 SSKAZ。SSKAT 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脚踝、肘部、臀部和手腕的类似设备，将这些组件集成到训练模型中，并考虑针对男性、女性和儿童的不同扭矩曲线。
