Acupuncture, a therapy within traditional Chinese medicine Traditional Chinese Medicine Originating > 2000 yr ago, traditional Chinese medicine (TCM) is a medical system based on the philosophy that illness results from improper flow of the life force (qi). The movement of qi is... read more , is one of the most widely accepted complementary therapies in the western world and is often part of integrative medicine. Specific points on the body are stimulated, usually by inserting thin needles into the skin and underlying tissues. Stimulating these specific points is believed to affect the flow of qi (a universal life force) along energy pathways (meridians) and thus restore balance.

The procedure is generally not painful but may cause a tingling sensation. Sometimes stimulation is increased by twisting, warming, or otherwise manipulating the needle.

Acupuncture points may also be stimulated by

  • Pressure (called acupressure)

  • Lasers

  • Ultrasound

  • A very low voltage electrical current (called electroacupuncture) applied to the needle

Evidence and Uses of Acupuncture

Acupuncture research is inherently difficult to conduct. Blinding is challenging and so-called "sham" acupuncture often puts pressure on acupressure points, thereby creating a different treatment experience that may not be truly inert. In some regions, particularly in China, published acupuncture studies tend to show a more positive effect. This may reflect bias, but it could also be that these providers are practicing the full schema of traditional Chinese medicine of which acupuncture is only a component.

The World Health Organization (WHO) has helped with this clinical challenge by issuing a list of conditions for which they have deemed evidence of efficacy to be strong or available but for which additional study is recommended, including

  • Symptoms of cancer therapy

  • Depression

  • Dysmenorrhea

  • Pain

  • Headache

  • Hypertension

  • Post-operative symptoms

  • Some complications of pregnancy

  • Stroke complications

Possible Adverse Effects and Contraindications

Adverse effects of acupuncture are probably underreported, although treatments are generally safe. A 2012 review of adverse effects that were reported after acupuncture noted the following (1 Reference Acupuncture, a therapy within traditional Chinese medicine, is one of the most widely accepted complementary therapies in the western world and is often part of integrative medicine.

  • Retained needles (31%)

  • Dizziness (30%)

  • Loss of consciousness or unresponsiveness (19%)

  • Falls (4%)

  • Bruising or soreness at the needle site (2%)

  • Pneumothorax (1%)

  • Other adverse effects (12%)

Most (95%) were classified as causing little or no harm.

When correctly done, acupuncture is fairly safe, but skill and care vary among practitioners.
