[Lifting-thrusting and rotating manipulations: a comparison on energy input].

Area of Science:

• Physics
• Biophysics
• Traditional Chinese Medicine

Background:

• Acupuncture meridians are traditionally understood pathways.
• The physical mechanisms underlying acupuncture manipulation energy transfer remain unclear.

Purpose of the Study:

• To quantitatively analyze the energy characteristics of acupuncture manipulations.
• To explore the physical nature of meridians and needling techniques.

Main Methods:

• Applied physics principles (energy density, flux, sound intensity) to an energy input model of acupuncture manipulations (lifting-thrusting, rotating).
• Calculated average energy flux intensity and Poynting vector frequency distributions in the infrasound range.
• Analyzed heat-producing (reinforcing) and coolness-producing (reducing) needling effects.

Main Results:

• Acupuncture manipulations exhibit high energy flux density and sound intensity levels.
• Meridians are hypothesized to be fascial tissues rich in elastic and collagenous fibers.
• Heat-producing needling (forceful thrusting) correlates with same-position solitary waves; coolness-producing needling (forceful lifting) correlates with opposite-position solitary waves.
• Manipulation speed significantly impacts energy transmission; rotating manipulation energy transmits better through meridians.

Conclusions:

• Acupuncture's energetic effects can be described using physical models.
• Fascial tissue composition may explain meridian properties.
• Solitary wave dynamics offer a potential explanation for different needling effects.
