According to TCM theory, acupuncture treatment influences life force energy, called qi or chi, that flows through the body along channels called meridians. The flow of qi through the meridians indicates a person’s health. If there is a disruption in one’s qi, acupuncture is used to restore the flow and bring the person back in “balance” and to optimal health.
Neuroscience research suggests that acupuncture works by modifying the nervous system through stimulation of specific points throughout the body. The application of very fine needles to these points, or needling, releases neurotransmitters, like endorphins and serotonin, that relieve pain and stimulate feelings of well-being.
The most common form of acupuncture involves the placement of solid, sterile, thin, stainless steel needles into various points on the body. Different techniques can be used to stimulate the needles. The 3 key methods used in acupuncture to stimulate the needles include manual stimulation, electrical stimulation, and application of heat.
Stimulation: Twisting, turning, and pulling the needle up and down after insertion.
Electrical Stimulation: Sending electrical pulses to the needles at different frequencies and waveforms using a handheld device.
Heat Stimulation: Traditionally, moxa (a dried herb) is placed on the top of the needles and burned. In modern use, infrared heat sources are used to warm up the needles.
