title: Satoyoshi's syndrome related muscle spasms: functional study.
abstract: Satoyoshi syndrome is a rare disease presumed to be immunologically mediated, characterized by muscle spasms, alopecia and diarrhea. We describe the case of a female in whom the muscle spasms were the predominant feature and we analyze the changes in cortical and in spinal excitability under the paired pulses paradigm. Hyperexcitability was present in the H-reflex study, thus suggesting that the spinal cord is the structure most likely responsible for the spasms. This is the first reported case in Spain.
