Change in Dielectric Constant, Elasticity and Temperature by Acupuncture

Not Applicable

• Conditions: Acupuncture
• Interventions: Other: Systemic acupuncture

• Registration Number: NCT04919746
• Lead Sponsor: University of Sao Paulo

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).

Arm && Interventions

Group	Intervention	Description
Group Acupuncture 1 - GA1	Systemic acupuncture	Healthy individuals aged between 18 and 38 years. The dielectric constant will be evaluated with a depth measurement of 0.5 mm, elasticity and infrared thermography in the region of the systemic acupuncture points.
Group Acupuncture 2 - GA2	Systemic acupuncture	Healthy individuals aged between 18 and 38 years. The dielectric constant will be evaluated with a depth measurement of 2.5 mm, elasticity and infrared thermography in the region of the systemic acupuncture points.
Group Acupuncture 3 - GA3	Systemic acupuncture	Healthy individuals aged between 18 and 38 years. The dielectric constant will be evaluated with a depth measurement of 5.0 mm, elasticity and infrared thermography in the region of the systemic acupuncture points.
