无支撑或“反重力”伸手和手张开运动在偏瘫中风患者中严重受损。伸展偏移和手张开的减少被认为主要受到肩外展肌与远端肢体屈肌的异常肌肉共同激活（称为屈曲协同作用）的限制，这导致独立关节控制或关节个性化的丧失。我们的实验室采用了几种方法来量化这种运动障碍，但最有记录的技术是复杂的和基于实验室的。这里详细概述了一系列机器人方法，这些方法的复杂性从全面（基于实验室）到集中（临床相关），以促进翻译并提出建议，作为神经工程和康复主题系列杂志的一部分，“感觉运动康复的技术先进评估”。虽然这些方法集中在我们利用设备ACT3D的已发表工作上，但这些方法可以使用具有适当特性的任何机电设备进行复制。所述方法的共同思路和最重要的方面是解决外展载荷的有害影响。远端上肢关节性能直接和单调调制近端（肩外展）关节的需求。机器人指标的就业是选择性地操纵肩外展任务的要求跨越个人的肩外展力量的全方位的最佳工具。从一系列方法和结论性建议中，科学家和临床医生可以确定理想的机器人量化方法，用于测量失去独立关节控制对伸手和手部功能的影响。
Unsupported or “against-gravity” reaching and hand opening movements are greatly impaired in individuals with hemiparetic stroke. The reduction in reaching excursion and hand opening is thought to be primarily limited by abnormal muscle co-activation of shoulder abductors with distal limb flexors, known as flexion synergy, that results in a loss of independent joint control or joint individuation. Our laboratory employs several methods for quantifying this movement impairment, however the most documented techniques are sophisticated and laboratory-based. Here a series of robotic methods that vary in complexity from comprehensive (laboratory-based) to focused (clinically relevant) are outlined in detail in order to facilitate translation and make recommendations for utilization across the translational spectrum as part of Journal of NeuroEngineering and Rehabilitation thematic series, “Technically-advanced assessments in sensory motor rehabilitation.” While these methods focus on our published work utilizing the device, ACT3D, these methods can be duplicated using any mechatronic device with the appropriate characteristics. The common thread and most important aspect of the methods described is addressing the deleterious effects of abduction loading. Distal upper extremity joint performance is directly and monotonically modulated by proximal (shoulder abduction) joint demands. The employment of robotic metrics is the best tool for selectively manipulating shoulder abduction task requirements spanning the individual’s full range of shoulder abduction strength. From the series of methods and the concluding recommendations, scientists and clinicians can determine the ideal robotic quantification method for the measurement of the impact of loss of independent joint control on reaching and hand function.
