What kind of study was this?

This was a systematic review and meta-analysis of 39 studies published up to December 31, 2015.

Who? The studies included 20,827 people who had musculoskeletal pain (back or neck), shoulder pain, chronic headache or pain due to osteoarthritis. The pain had to be present for at least 4 weeks.

What? The reviewers included studies that compared acupuncture with sham acupuncture or with usual care.

Acupuncture

vs

Sham acupuncture or Usual care

Acupuncture: technique of inserting thin needles through the skin and pushing them down to a certain level at specific sites on the body to reduce pain or other symptoms

The included studies used Chinese acupuncture, Western acupuncture or a combination of both.

The number of treatments varied across the studies (average of 6-10 once-weekly sessions lasting for approximately 30 minutes)


Sham acupuncture: needles used but not with the correct technique

Usual care: treatment without needles such as physiotherapy or medications to reduce pain and inflammation (varied across studies)


Why was this research done?

Acupuncture has been practised in some parts of the world for thousands of years. However, some health care providers question whether it is effective at treating conditions like chronic pain. It is thought that a patient's belief that acupuncture works may be responsible for the positive results experienced by some patients and not the treatment itself - this is called the placebo effect. The authors of this review collected data from 39 individual studies comparing acupuncture with either sham acupuncture or usual care. When combined together, these studies provide a more accurate picture of the likelihood that acupuncture is effective in reducing chronic pain.
