DESCRIPTION (provided by applicant): The development and clinical evaluation of a tendon actuator is proposed that will match the force and motion characteristics of muscles responsible for controlling foot motion. The tendon actuator will attach to a cadaver foot tendon and will allow biomechanics researchers to manipulate the foot. Ultimately, a tendon actuator system, consisting of an array of eight tendon actuators, will enable the foot to be controlled in all degrees of freedom, in order to understand the etiology of a wide range of foot pathologies. In addition, the tendon actuator will be designed to integrate with the musculoskeletal simulator at the Cleveland Clinic Foundation (CCF), making it possible for the simulator to precisely mimic both gait kinematics and the stress distribution present on the underside of the foot. Eventually this system will be adapted to investigate human kinematics and pathologies in additional anatomic regions such as the wrist, shoulder, spine and knee. Initially, the program will focus on development of an Achilles tendon actuator capable of precisely tracking a prescribed demanding force profile accompanied by potentially demanding velocity, acceleration, travel and bandwidth requirements. After completion and test of a tendon actuator prototype at Foster-Miller, it will be attached to a cadaver and tested at the Biomechanics laboratory at CCF. The cadaver foot will be manipulated by attaching the Achilles tendon to the tendon actuator and mounting the tibia and fibula of the foot to an MTS system force actuator. A follow-on Phase II will include integration of a foot tendon actuator system (consisting of a full array of eight tendon actuators) with a cadaver foot and the musculoskeletal simulator to allow control of the cadaver foot in all degrees of freedom.

描述（由申请人提供）：提出了肌腱执行器的开发和临床评估，该评估将与负责控制足运动的肌肉的力和运动特征相匹配。肌腱执行器将附着在尸体肌腱上，并允许生物力学研究人员操纵脚。最终，由八个肌腱执行器组成的肌腱执行器系统将使脚以各个自由度进行控制，以了解广泛的脚部病理学的病因。此外，肌腱执行器将设计为与克利夫兰诊所基金会（CCF）的肌肉骨骼模拟器进行整合，使模拟器可以精确模拟步态运动学和脚部下方存在的压力分布。最终，该系统将适应于其他解剖区域（例如腕，肩膀，脊柱和膝盖）中的人体运动学和病理。 最初，该计划将着重于开发跟腱执行器，能够精确跟踪规定的苛刻的力量概况，并伴随着潜在的速度，加速度，旅行和带宽要求。在Foster-Miller的肌腱执行器原型完成和测试后，它将连接到尸体上，并在CCF的生物力学实验室进行测试。将尸体脚连接到肌腱执行器上，并将脚胫骨和腓骨安装到MTS系统力执行器上来操纵尸体。后续第二阶段将包括将脚肌腱执行器系统（由八个肌腱致动器组成）和尸体脚和肌肉骨骼模拟器的整合，以使尸体脚以各个自由度控制。
