Abstract
Abstract An apparatus and method for treating a patient suffering from motion sickness such as air sickness and the like. The method includes the steps of applying electrodes to the vestibular area of the patient's head and providing current pulses in the current range of 0.5-3.8 mA, the pulses having a frequency in the range of 1-5 pulses per second and a pulse width in the range of 100-200 msec. The apparatus comprises a timing generator for determining pulse frequency, an impulse generator for generating a pulse waveform, an impulse former for controlling pulse shape and a driver stage for developing current pulses to be applied to the electrodes.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
80 words
A method for treating a patient afflicted with space sickness, air sickness, dizziness, sea sickness or the like comprising the steps of: (a) applying electrodes to the patient; (b) applying pulses of current through said electrodes to the patient to stimulate the patient's vestibular nerve, said pulses being in a frequency range of 1 to 5 pulses per second, the pulses having a pulse width in the range of 100-300 msecs., the current being in the range of 0.5-3.8 mA.
Claim 2
Independent Claim
80 words
A method for treating a patient afflicted with space sickness, air sickness, dizziness, sea sickness or the like comprising the steps of: (a) applying electrodes to the patient; (b) applying pulses of current through said electrodes to the patient to stimulate the patient's vestibular nerve, said pulses being in a frequency range of 1 to 5 pulses per second, the pulses having a pulse width in the range of 100-300 msecs., the current being in the range of 0.5-3.8 mA.
