The invention provides a wearable pulse modulation
magneto-acoustic stimulation device for improving
cognitive impairment of old people, which is a head-mounted portable
magneto-acoustic stimulation
rehabilitation assistive device and comprises a coil, a
loudspeaker, a head sleeve, a power supply, a
voltage converter, a
relay, a controller, an audio module, a cable and a strap. The
system generates a subthreshold low-intensity pulsed
magnetic field of a gamma
frequency band and a modulated sound
signal of a theta
frequency band, and compared with single magnetic stimulation, magnetoacoustic
coupling can improve the effectiveness of nerve regulation and control. The low-intensity pulsed
magnetic field acts on the
frontal lobe, the low-frequency modulated sound
signal acts on the
temporal lobe, and the magnetic stimulation and the
sound stimulation coordinate to adjust
neural activity, so that the inhibited electroencephalogram
signal of the gamma-
frequency band of a patient is enhanced, the electroencephalogram activity of the theta-frequency band is recovered to be normal, and the
cognitive disorder is improved. The
system can be used by a patient independently or with the help of other people, the problem that the patient is inconvenient to see a doctor is solved, and the
system is a novel
home nursing technology and a novel device which are safe, efficient, portable and wearable.
