Abstract:
1. A method of testing a subject for brain injury comprising the steps of: (a) monitoring the sleep movements of a subject using movement sensors operable at a sampling rate of at least 10 Hz to generate a plurality of temporally-associated data signals relating to sleep movements; (b) parsing the data at least once into a plurality of bins of defined temporal duration of 60 seconds or less, and determining an average value for each bin to differentiate bouts of micro-structural movements from bouts of quiescence and bouts of macro-structural movements; and identifying a period of 1-3 hours during which the data signals include no movements indicative of frank awakenings, and wherein step (b) includes the following sub-steps applied to the data of said period: (c) comparing the values for bouts of micro-structural movements to a threshold value that is indicative of brain injury; and (d) assigning a determination of brain injury according to the outcome of the comparison.
