APPLICATION OF LOW-POWER SEMICONDUCTOR LASER WITH 940NM WAVELENGTH AND 10 INDEPENDENT CHANNELS IN TREATING HEMIPLEGIA SEQUELAE DUE TO STROKE

Abstract

Phototherapy is a supportive treatment method that has proven its therapeutic effects and noticeable social significance through many studies and practical applications around the world and in the country. This article introduces a method of using a low-power semiconductor laser light source with the advantage of monochromaticity, ensuring appropriate power, and capable of creating biological stimulation effects with a wavelength of 940nm and a controlled frequency for each disease so as to support physical therapy, especially treating the symptoms of numbness - paralysis - pain - aches. The low-power semiconductor laser photomagnetic device is manufactured with a low-power of 0-14mM, emitting radiation in the form of a single laser emitter with a wavelength of 940nm. The device’s modulation frequency is adjusted to the biological frequency from 5Hz to 100 Hz.
