Huntington's chorea. A random process.
The purpose of the present study was to investigate statistically the irregular nature of the choreatic jerks in Huntington's Chorea. EMG-bursts of certain muscles in a patient with Huntington's Chorea were taken as a measure of the jerks. Statistical analysis of the measurements, i.e. durations of bursts and intervals between bursts, revealed that the irregular nature of the choreatic jerks originate from a random process. Each choreatic jerk appears to be an entirely independent and unpredictable event.
