We developed a quantitative grasp and release test for assessing a hand neuroprosthesis in C5 and C6 level tetraplegic patients. The objectives were (1) to determine if a patient's hand performance with the neuroprosthesis exceeded a defined, clinically acceptable baseline, (2) to compare performance with and without the neuroprosthesis, (3) to measure the consistency of performance over time, and (4) to compare performance among patients. In the test, patients grasped, moved, and released one of six different objects as many times as possible in five 30-second trials for each object, with and without the neuroprosthesis. Unlike earlier tests, the objects and the task were chosen to span a range of difficulties appropriate for C5 and C6 tetraplegic patients using a hand neuroprosthesis. Data from five patients showed that performance with the neuroprosthesis was above the baseline; performance improved with the neuroprosthesis, although it was not generally consistent across sessions; and the neuroprosthesis helped C5 patients manipulate most objects and helped C6 patients primarily with more difficult objects.
我们开发了一种定量抓握和松开测试，用于评估C5和C6级四肢瘫痪患者的手部神经假体。目标包括：（1）确定患者使用神经假体时的手部表现是否超过定义的、临床上可接受的基线；（2）比较使用和不使用神经假体时的表现；（3）测量随时间推移表现的一致性；（4）比较患者之间的表现。在测试中，患者在有和没有神经假体的情况下，针对六个不同物体中的一个，在每次物体的五次30秒试验中尽可能多地进行抓握、移动和松开动作。与早期测试不同，此次选择的物体和任务涵盖了一系列适合使用手部神经假体的C5和C6级四肢瘫痪患者的难度范围。来自五名患者的数据表明，使用神经假体时的表现高于基线；虽然各次测试的表现通常不一致，但使用神经假体时表现有所改善；神经假体帮助C5级患者操作大多数物体，并主要帮助C6级患者操作更困难的物体。
