Clinical Trial Summary

Transcranial infrared laser stimulation is a non-invasive neuromodulation technique. The study will examine the effect of transcranial infrared laser stimulation on cardiovascular and metabolic responses to stress.

Description:

Physiological responses to stress may be a potential pathway by which psychological stress relates to cardiovascular disease. Disproportionate (metabolically exaggerated) stressor-evoked cardiovascular reactions may accelerate atherosclerosis or influence risk of greater cardiovascular disease endpoints. The aim of this project is to use an experimental approach to examine if neuromodulation (transcranial infrared laser stimulation) alters stressor-evoked metabolic and cardiovascular responses.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Oxygen consumption in response to acute psychological stress	This measurement takes into account oxygen consumption at baseline and during the stress task.	Immediately following intervention (up to 60 minutes)
Primary	Heart rate in response to acute psychological stress	This measurement takes into account heart rate at baseline and during the stress task.	Immediately following intervention (up to 60 minutes)
Primary	Additional heart rate in response to acute psychological stress	This measurement takes into account additional heart rate at baseline and during stress.	Immediately following intervention (up to 60 minutes)
Secondary	Perceived stress	Ratings of perceived stressfulness (1 = not at all stressful, 7 = very stressful) of the acute psychological stress task	Immediately following intervention (up to 60 minutes)
