“…According to the literature, stimulating Neiguan can sedate nerves, regulate qi, and relieve pain. Modern research also confirmed that stimulating Neiguan can strengthen myocardial contractility and improve cardiac output and other cardiac functions [18–21]. We hypothesize that stimulating Neiguan with an emulated laser acupuncture instrument may increase blood flow, improve the peripheral circulation, and accordingly increase the temperature of the hand.…”

Acupuncture manipulation is one of the key factors affecting the performance of acupuncture in Traditional Chinese Medicine. Lift-thrust and twirl-twist are two of the most commonly used manipulation methods for needle acupuncture. We previously have developed a novel laser acupuncture model that emulates lift-thrust operation. In this study, we intend to show the effectiveness of such a model by applying it on the Neiguan acupoint (PC6). Stimulation was reported to be beneficial for improving cardiac output and peripheral circulation. Therefore, we hypothesized that the stimulation of laser acupuncture may increase the temperature of the subjects' fingertip due to increased peripheral blood flow. A thermal imager was used to measure the temperature change of subjects' fingertips. Through regression analysis, it has been shown that while PC6 is stimulated, laser acupuncture with lift-thrust operation caused a more rapid, stable, and lasting temperature rise of fingertip than that without lift-thrust operation. On the contrary, we observe no significant temperature change when a sham point nearby PC6 (a point which is not traditionally defined as the acupoint) was stimulated. Our results suggest the emulation of manipulation methods such as the lift-thrust operation could be a potential direction for the future development of laser acupuncture.

“…En estudios previos se encontró que la acupuntura en PC6 modifica de manera favorable y significativa desde el punto de vista estadístico el índice IE en sujetos no fumadores, y la comparación de los sujetos no fumadores versus fumadores mostró diferencia significativa en el índice BA (Rivas et al, 2008).…”

“…El tabaquismo es un factor de riesgo considerable en el desarrollo y evolución de la enfermedad cardiovascular y progresión de la ateroesclerosis a través de cambios agudos en el sistema de la coagulación, los vasos sanguíneos y el metabolismo de las lipoproteínas ; las mediciones del índice de aumento aórtico (AIx) y la velocidad de la onda de pulso (PWV), así como la tensión arterial central, son notablemente más altas después de fumar, y son considerablemente más altos en los fumadores crónicos. El deterioro de la función vasodilatadora es una de las primeras manifestaciones de los cambios ateroescleróticos en un vaso sanguíneo Rivas et al, 2008;Hansson, 2005).…”

Introduction. PC6 or Neiguan is an acupoint broadly used in clinical acupuncture for the treatment of several diseases, mainly cardiovascular disorders. Nonetheless, its effects on cardiovascular physiopathology have not been fully described. Previous studies have shown that acupuncture at PC6 changes indices related to vascular distensibility of large and medium sized arterial vessels. It has been postulated that the PC6 stimulation modifies cardiovascular reflex responses. The aim of this study was to compare the effect of acupuncture point PC6 on cardiovascular variables in non smokers versus smokers.Subjects and methods. Systolic, diastolic, mean arterial pressures, heart rate an stroke volume were determined. These parameters were studied in a population divided into two groups constituted as follows : group A 15 non smoking subjects , 8 women aged 20 -30 years ( 23.8 ± 3.27, mean ± SD) and 7 males aged 20 -30 years ( 27 ± 3.6 , mean ± SD) , and group B 15 smokers, 10 women aged 20 -30 years ( 25.9 ± 3.5 , mean ± SD) and 5 men aged 20 -30 (24.6 ± 3.21 , mean ± SD). In each subject a 20 minute period was recorded. An 2.54 cm in lenght and 0.32 mm in diameter was manually inserted and keep in situ during 5 minutes. Segments were compared of these three registration periods: baseline 0-300 s, transacupuncture 301 -600, and posacupuncture 601 -1200 s.x Results. The main findings were as follows: significant increase in systolic pressure in both experimental groups and with both points left and right; significant increase in diastolyc pressure in both experimental groups with PC6 left; significant increase mean arterial pressure in both experimental groups with PC6 left; significant decrease in heart rate with PC6 right in both experimental groups, and PC6 left in the smokers group, significant increase in stroke volume with PC6 right or PC6 left in smokers and PC6 left in the non smoking group. Conclusion.These findings suggest that manual stimulation of PC6 significantly modifies the parameters examined, and left or right PC6 produce distinct effects on the variables examined.

Vascular Responses to Manual PC6 Acupuncture in Nonsmokers and Smokers Assessed by the Second Derivative of the Finger Photoplethysmogram Waveform

Abstract: These findings suggest that manual needling with PC6 could revert some of the deleterious effects on vascular functioning produced by chronic cigarette smoking.
