Effect of Stress-free Therapy on Cerebral Blood Flow: Comparisons among patients with metabolic cardiovascular disease, healthy subjects and placebo-treated subjects.

BACKGROUND AND AIMS: We have developed a Stress-free Therapy(®) device wherein "Pinpoint Plantar Long-wavelength Infrared Light Irradiation (PP-LILI)" increases peripheral-deep body temperature and blood flow volume and stabilizes blood pressure as well as significantly reduces stress hormones such as adrenocorticotrophic hormone and cortisol without using drugs. Moreover, we have found this therapy to significantly improve blood glucose and insulin resistance in patients with type 2 diabetes. Based on this background of clinical efficacy, we validated changes in cerebral blood flow in patients with metabolic cardiovascular disease and examined the efficacy of Stress-free Therapy(®) on cerebral blood flow as compared to that in healthy control subjects and placebo-treated patients.
RESULTS: The change in cerebral blood flow volume during 15-minute PP-LILI was 5.1 ± 1.8 mL/min in patients with metabolic cardiovascular disease, showing a significant increase (P<0.05) of 3.1 mL/min as compared with the mean blood flow value after resting for 15 minutes.
CONCLUSIONS: Our results suggested Stress-free Therapy(®) to significantly increase cerebral blood flow, possibly leading to the prevention of metabolic cardiovascular disease.
