机器人工程界已经广泛探索了用于治疗中风、创伤性脑损伤和脑瘫所致的慢性运动障碍的电动手矫形器和外骨骼的开发。由这些疾病引起的疾病有几种形式，对于那些与患者互动有限的人来说，各种缺陷的临床描述有时很难解释。由于通常根据帮助闭手的能力来设计和评估设备，这些患者中存在的众所周知的伸展缺陷通常只会得到机器人方法的次要考虑。以一种易于转化为工程设计标准的方式对这些扩展缺陷进行定量表征将极大地有利于设备设计和评估。在这里，我们测量了三名手部屈肌张力增加的患者的食指和拇指伸展所需的外力矩。完全伸展受试者食指MCP关节所需的平均扭矩范围从-lt；内嵌公式-公式；<；纹理-数学符号=“LaTeX”>；$0.22-0.75\，\文本{N}\cdot\text{m}$<；/tex-math>；<；/inline-formula>；和拇指的MCP。$0.29-1.35\，\文本{N}\cot\text{m}$<；/tex-math>；<；/inline-formula>；.当受试者被要求随意伸展手指时，记录到的扭矩最大，这导致需要更多帮助才能克服的屈肌语调比放松时增加。
The development of powered hand orthoses and exoskeletons for treatment of chronic motor deficits due to stroke, traumatic brain injury, and cerebral palsy has been widely explored by the robotics engineering community. The conditions arising from these disorders take several forms and clinical descriptions of the various deficits are at times difficult to interpret for those with limited interaction with patients. With devices commonly designed and evaluated on their ability to aid hand closure, well-known extension deficits that are present among these patients typically receive only secondary consideration by robotic approaches. Quantitative characterization of these extension deficits in a manner that is easily translated into engineering design criteria would greatly benefit device design and evaluation. Here, we measure the externally applied torques required to assist extension of the index finger and thumb of three patients with increased flexor tone in the hand. The average torque required to fully extend a subject's index finger MCP joint ranged from <inline-formula><tex-math notation="LaTeX">$0.22-0.75\,\text{N}\cdot \text{m}$</tex-math></inline-formula> and the thumb's MCP from <inline-formula><tex-math notation="LaTeX"> $0.29-1.35\,\text{N} \cdot \text{m}$</tex-math></inline-formula>. The highest torques were recorded when subjects were asked to volitionally extend their fingers, causing an increase in flexor tone requiring more assistance to overcome than when they were relaxed.
