If slain in the spirit is unpredictable falling down or losing use or control of the skeletal muscles then it may be a form of 'myotonia congenita'?
If induced by auditory stimuli then the evidence suggests it is self induced, there are even some how-to videos available on-line. Example
I don't think that 'be slain in the spirit' should be in anyway associated with being moved by the Holy Ghost.
