Acupuncture is the insertion of very fine, filiform needles through the skin at specific points on the body with the intention of manipulating Qi. The filiform needles are solid, as opposed to the hollow hypodermic needles most people are familiar with, and are usually made of stainless steel, but can also be gold or silver.
Needles are inserted to a depth of 4–25 mm and left in place for a period of time (from a few seconds to many minutes). There are often 6–12 needles (and sometimes more) inserted at different acupoints at the same time. The sensation is often described as a tingling or dull ache at the entry point. Many people say they feel very relaxed or sleepy, and some report increased energy levels afterwards.
Electro acupuncture (EA)
A tiny focused electric current is applied to the skin at the acupoints or can be applied to the needle itself. There are various modalities to consider.
In laser acupuncture, a fine low-energy laser beam is directed onto the acupoint.
Here, pressure is used to stimulate the acupoints. This can be in the form of a bracelet or strap. This method is commonly used to alleviate motion sickness.
