尽管最近已经开发了许多设备来促进中风后的手部康复，但大多数设备对数字或手臂的移动施加了一些限制。因此，开发了一个新颖的手套，可以为每个数字提供独立的扩展援助，同时仍允许全手动移动。这种气动手套，即pneuglove，可用于训练用真实对象或在虚拟现实环境中使用虚拟对象训练和释放运动。两组中风幸存者，每组有七个受试者，完成了为期六周的康复训练方案，包括每周举行的三个1小时课程。一个小组在训练期间穿着pneuglove，在新颖的虚拟现实环境中以及在其外部使用物理对象进行了执行，而另一组则在没有设备的情况下完成了相同的培训。在整个受试者中，在FUGL-MEYER评估中观察到了显着改善（p <0.001），Fugl-Meyer评估的手/腕部部分（P <0.001），盒子和阻塞测试（P <0.05）（p <0.05）和Palmar Pinch强度（P <0.05）。尽管两组的变化在统计学上没有不同，但使用pneuglove的组确实对这些措施的每种措施表现出更大的平均改进，例如，FUGL-MEYER评估的手/腕部部分的增长为3.7 v和2.4分和14 N在Palmar Pinch中与5N相比。
While a number of devices have recently been developed to facilitate hand rehabilitation after stroke, most place some restrictions on movement of the digits or arm. Thus, a novel glove was developed which can provide independent extension assistance to each digit while still allowing full arm movement. This pneumatic glove, the PneuGlove, can be used for training grasp-and-release movements either with real objects or with virtual objects in a virtual reality environment. Two groups of stroke survivors, with seven subjects in each group, completed a six-week rehabilitation training protocol, consisting of three 1-h sessions held each week. One group wore the PneuGlove during training, performed both within a novel virtual reality environment and outside of it with physical objects, while the other group completed the same training without the device. Across subjects, significant improvements were observed in the Fugl-Meyer Assessment for the upper extremity (p < 0.001), the hand/wrist portion of the Fugl-Meyer Assessment (p < 0.001), the Box and Blocks test (p < 0.05), and palmar pinch strength (p < 0.05). While changes in the two groups were not statistically different, the group using the PneuGlove did show greater mean improvement on each of these measures, such as gains of 3.7 versus 2.4 points on the hand/wrist portion of the Fugl-Meyer Assessment and 14 N versus 5 N in palmar pinch.
