Brief summary

Evaluate the effect of systemic acupuncture on dielectric constant, elasticity and skin temperature in healthy individuals.

Detailed description

Systemic acupuncture is a therapeutic resource in Chinese Medicine that uses needles at specific points in the body, consistent with a system called acupuncture meridians. The aim of the study is to evaluate the effect of systemic acupuncture on dielectric constant, elasticity and skin temperature in healthy individuals. Will be evaluated 360 volunteers aged between 18 and 38 years and both sexes divided into six homogeneous groups. Pregnant women or those with a delay in the menstrual cycle for more than 28 days will be excluded. The evaluation will consist of measuring the dielectric constant at different depths of the skin, elasticity and infrared thermography of systemic acupuncture points. The procedure will be performed in three moments: pre systemic acupuncture (prior to stimulation), immediate post-systemic acupuncture (20 minutes after the start of stimulation), and post systemic acupuncture (40 minutes after the start of stimulation). Systemic acupuncture will be performed on the lower limb, bilaterally, at points E36 (Zusanli) and BP6 (Sanyinjiao), lasting 20 minutes. The multiple comparison ANOVA test will be performed, with statistical significance of 5% (p \< 0.05).

Interventions

OTHERSystemic acupuncture

Systemic acupuncture will be performed on the lower limb, bilaterally, at points E36 (Zusanli) and BP6 (Sanyinjiao). Point location specificity will be determined using the anatomical and directional F-cun reference method. Stimulation of pre-defined points will be performed using needles with a threadlike, sterile, disposable character and size 0.25 x 30.0 mm, within a period of 20 minutes. The insertion of the needle will be at a depth of 0.5 inches, aiming to obtain the De Qi, sensation of energy at the point and in the corresponding meridian, referring to the effectiveness of systemic acupuncture.
