Techniques
Neuroacupuncture uses defined zones of the scalp, and in some systems the forehead and body, to influence the nervous system. The main families are Chinese scalp acupuncture, Yamamoto New Scalp Acupuncture (YNSA) and ear acupuncture (auriculotherapy).
Chinese scalp acupuncture (头针, tóuzhēn) developed in China from the late 1950s and 1970s, when acupuncturists and physicians began mapping needling zones on the scalp onto the functional areas of the cerebral cortex beneath them. It combines classical channel theory with modern neuroanatomy.
Needles are inserted at a shallow angle along lines or zones and are usually stimulated by rapid manual rotation or electrical stimulation, often while the patient moves the affected limb. It is best known for stroke rehabilitation and is also used for other neurological conditions, pain and functional disorders.
Several schools developed in parallel. They share the principle of scalp zones but differ in their maps and stimulation methods. Further schools and regional variations exist, and partner schools are welcome to present their own method here.
Developed by the neurosurgeon Jiao Shunfa in Shanxi province around 1971. Stimulation areas such as the motor, sensory and balance areas are projected directly from the cerebral cortex onto the scalp. Often regarded as the starting point of modern scalp acupuncture.
Head acupuncture by Fang Yunpeng of Xi’an, based on figures of the human body projected onto the scalp and on the cortical areas for speech, writing and movement.
Zhu’s scalp acupuncture divides the scalp into bands linked to body regions and organ systems and combines needling with guided movement, breathing and rehabilitation exercises.
Developed in Heilongjiang. Uses scalp zones over the relevant cortical areas with long needle retention, and is widely used in Chinese rehabilitation hospitals.
In the 1980s the China Association of Acupuncture and Moxibustion standardised 14 scalp lines (MS1 to MS14), later adopted in the WHO Standard Acupuncture Nomenclature. Many textbooks and studies refer to these lines.
Dr. Lin Xuejian worked with Jiao Shunfa’s method and extended it, adding further areas and stimulation zones to his scalp map.
YNSA was developed by the Japanese physician Dr Toshikatsu Yamamoto, who presented it in 1973. It is a microsystem: the whole body is represented in small somatotopes on the forehead, scalp and other regions.
The system includes basic points for the locomotor system and sensory organs, brain points, and Y-points related to internal organs. Treatment points are selected using characteristic diagnostic zones, especially at the neck and abdomen. Needling is very precise and typically gives rapid, measurable changes in pain or mobility.
YNSA is used for pain of the locomotor system, neurological conditions such as stroke sequelae and paralysis, and many functional complaints.
Modern ear acupuncture goes back to the French physician Paul Nogier, who in the 1950s described a map of the whole body on the outer ear. Points on the ear are needled, pressed or stimulated electrically to treat pain and functional complaints.
The ear belongs under neuroacupuncture because it is unusually richly supplied by nerves that connect directly to the brainstem: the auricular branch of the vagus nerve, especially in the concha, together with branches of the trigeminal and cervical nerves.
Brain imaging supports this link. In an fMRI study, stimulation of the vagus-supplied part of the ear (cymba conchae) activated the nucleus of the solitary tract, the locus coeruleus and other vagal projection areas in the brain, more than stimulation of the earlobe did. Early imaging studies also suggest that ear points for parts of the body activate the matching regions of the sensory cortex.
Dr. David Alimi developed a neurophysiological approach to auriculotherapy that is used especially in pain treatment.
Neuroacupuncture should be applied by trained practitioners as part of a proper clinical assessment, and alongside conventional medical care for neurological conditions. Research into its effects is ongoing.
