Scalp acupuncture
Scalp acupuncture is a specialized form of acupuncture that has helped many people with nervous-system disorders, including spinal cord injury (SCI) and multiple sclerosis (MS). 
The leading force behind the therapy’s emergence has been Professor Ming Qing Zhu. A 1964 Shanghai University of Traditional Chinese Medicine graduate, Zhu has become an internationally recognized and acclaimed acupuncturist, who has authored many publications, including a scalp acupuncture textbook, and lectured throughout the world.

Although scalp acupuncture can treat most of the same disorders as traditional acupuncture, it is especially effective in treating nervous-system disorders and pain.
For example, studies have shown that scalp acupuncture has helped thousands of stroke patients, apparently through altering blood hormone levels that influence stroke-inducing platelet clumping.
In addition, numerous people with head injury have also benefited from scalp acupuncture.
Zhu believes the therapy is most effective when initiated soon after the traumatic injury or neurological crisis.

Treatment Procedure:
Very fine needles are painlessly inserted at a 15–30 degree angle into the thin layer of scalp tissue (see illustration) in treatment zones associated with specific body functions and regions to stimulate qi flow, the needles are periodically manipulated.
Because the needles are inserted in the scalp, the patient can receive treatment in any position, and the needles can be left in for extended, treatment-enhancing time periods without interfering with daily activities. Typically, the needles remain inserted for at least the two-hour clinic visit and often up to 72 hours.
While the needles are inserted, Zhu encourages patients to move the affected body parts or, at minimum, visualize the movement accompanied with breathing practices that help direct the qi flow to the intended area. He believes that such treatment-associated movement is critical in improving connections between the central and peripheral nervous system.
Even in paralysis cases, Zhu encourages these movements, using, as necessary, assistive devices or the help of others.
