One common trio of multiple sclerosis symptoms is called Charcot's neurologic triad and it includes dysarthria, which is difficulty or unclear speech, nystagmus, which is involuntary rapid eye movements, and an intention tremor.

常见的MS三联征，Charcot神三主征包括构音障碍（说话困难或不清）、眼球震（不自主的快速眼球运动）以及意向性震。

Finally, intention tremors can be caused by plaques along the motor pathways in the spinal cord which can affect outbound signals like skeletal muscle control.

意向性震是由于运动通路有斑块，干扰了控制骨骼肌的传出信号。
