In Chinese medicine, acupuncture dates back more than 2000 years. The Military Health System has developed a modern modification of this ancient practice, known as Battlefield Acupuncture, or BFA.
Military health care providers are finding that ear acupuncture, which involves inserting small needles into different areas of the ear, is successful in relieving pain of injured or ill service members.
“BFA is highly effective and markedly alleviates acute or chronic pain in approximately 80-85% of patients,” regardless of the underlying cause, said Dr. Jeff Leggit, a professor and medical acupuncturist at the Uniformed Services University of the Health Sciences [https://www.usuhs.edu/], in Bethesda, Maryland.
