A pivotted four-bar chain mechanism has been studied and built as a feeding aid for Parkinson's patients. This system provides a good feeding path. Guidance is by means of a spring restrained sliding handle. The tremor exhibited by three patients was established in constant force tests. Shake tests using simulated inputs spanning the frequency range indicated (2.5 Hz-6 Hz) established the vibration isolation properties of the system.
一种枢轴式四杆链机构已被研究并制造出来，作为帕金森病患者的进食辅助工具。该系统提供了一条良好的进食路径。通过弹簧约束的滑动手柄进行导向。在恒力测试中确定了三名患者表现出的震颤情况。使用跨越指定频率范围（2.5赫兹至6赫兹）的模拟输入进行的震动测试确定了该系统的隔振特性。
