According to the theory of traditional Chinese medicine, the cause of the quadriplegia of the apoplexy patient is the empty and deficient of the qi transmission of the channels and collaterals caused by the damage of the brain and marrow spirit. Common treatment methods include taking traditional Chinese medicine and acupuncture. The traditional acupuncture therapy is to insert a filiform needle into a specific acupoint of a patient's body by hand and to use acupuncture techniques such as twirling, lifting and inserting, etc., while the moxibustion therapy is to smoke and bake the specific acupoint with a burning moxa cone. The effects of both therapies can only be slowly manifested by multiple treatments over a longer period of time. In other words, for paralyzed limbs, the traditional Chinese medicine acupuncture and moxibustion cannot show the movement function in the treatment process.
