Laser parameters for efficient biomedical stimulation: A study to increase cognitive response rate

Technol Health Care. 2018;26(S1):419-425. doi: 10.3233/THC-174718.

Abstract

Background: The laser is able to irradiate the exact amount of stimulation to an area by a non contact method, and has the advantage of being able to stimulate the local target area.

Objective: This study examined an efficient method of laser tactile stimulation using laser parameter combinations.

Methods: The laser parameters that could cause an increase in the cognitive response rate of human subjects were examined without increasing the amount of total laser energy.

Results: As a result, the appropriate matching parameters such as duty ratio, pulse frequency, and exposure time of laser pulses showed a dominant influence in effectively increasing the tactile response rate of subjects with limited amount of total laser energy.

Conclusions: This study can be applied to neurophysiology, cognitive research, and clinical laser application.

Keywords: Laser tactile stimulation; diode pulse laser; laser parameter; tactile response rate.
