An apparatus for accurately monitoring motor movements attributable to seizures and convulsions of patients having epilepsy or other seizure disorders, and motor movements attributable to periodic leg movements, tremors, respiration, mechanical cardiac functions, or any other motorics during periods of sleep. This monitoring function is achieved without attaching any detection apparatus to the patient. Embodiments measure patient movements essentially by relating mattress displacement to such motor movements. The preferred embodiment is constructed with a geophone configuration intended to receive an analog signal corresponding to mattress movement and to communicate this signal to an electrically interconnected detection assembly for monitoring and recording the patient's pattern of body movements. Other suitable movement sensing devices such as devices based upon piezoelectric, fiber optics, microwave, infrared, and ultrasound phenomena may be used either in addition to or instead of geophones. The analog signals received by these sensors are then communicated to a computerized detection assembly wherein these signals are converted from waveforms to digital signals for subsequent analysis and remedial medical treatment as appropriate. |
