Rapid alternating hand movement is done by asking the patient to tap the palm of one hand with the fingers of the other, then rapidly turn over the fingers and tap the palm with the back of them, repeatedly. Dysdiadochokinesia (DDK) is caused by the inability to switch on and switch off antagonising muscle groups in a coordinated fashion. Dysdiadochokinesia is also seen in ataxia, multiple sclerosis, intention tremor and cerebellar tumors. The user can observe the coordination between hands and brain of the patient by playing the video.
