Fig 1. Four frames of video clip showing a typical episode in case 1. In this 16-year-old boy with CLS, an unexpected pull on the shoulders by the examiner leads to a sudden loss of tone with an abrupt drop to the ground. He recovers rapidly, and there is no loss of consciousness (see video clip 1). This brief episode occurs at 00:09 after the start of the clip. The numbers on the bottom left corner of each frame (MM:SS.000) represent the time after the stimulus.
