Nearly 8 out of every 10 people will have low back pain at some point in life. Back pain is one of the top reasons people seek medical treatment. It is also the No. 1 reported reason for seeking acupuncture. The good news is chronic low back pain is one of the conditions that research suggests acupuncture may be an effective tool for treating.
One recent review of 22 acupuncture studies showed that it provided short-term relief from chronic back pain. It also showed there was greater improvement in pain for people who got acupuncture compared to those who received a “sham” treatment. Other studies have found, though, that sham acupuncture can be as effective as actual acupuncture. Those studies also found that, compared to standard treatment, both actual acupuncture and sham acupuncture are more effective.
Laminectomy is one of the most common back surgeries. During a laminectomy, a surgeon removes the rear portion of one or more spinal bones (vertebrae). Bone spurs and ligaments that are pressing on nerves may be removed at the same time. Here's what to expect before, during, and after your laminectomy.
Guidelines from the American Pain Society and American College of Physicians say doctors should consider acupuncture as an alternative therapy for patients with chronic low-back pain that's not helped by conventional treatment.
How Acupuncture Appears to Help Back Pain
Acupuncture began in China more than 2,500 years ago. It involves inserting thin needles at certain points on the body. According to traditional Chinese medicine, the body has more than 2,000 of these points. They are connected by pathways or meridians, which create a flow of energy called Qi (pronounced “chee”). Stimulating these points is said to correct the imbalance of qi and improve the flow of energy. Practitioners believe that this helps relieve pain and improve health.
It's thought the effects come from stimulating the central nervous system. This may trigger the release of chemicals into the muscles, spinal cord, and brain. These chemicals either alter the experience of pain or produce bodily changes that promote a sense of well-being.
Other theories suggest acupuncture works by:
Speeding the relay of electromagnetic signals. This may begin the flow of pain-killing chemicals such as endorphins. Or it may release immune system cells in the body.
Triggering the release of natural opioids. These are chemicals in the brain that may lessen pain or promote sleep.
Changing brain chemistry by altering the release of neurotransmitters and neurohormones. Neurotransmitters either stimulate or dampen nerve impulses. Neurohormones can affect the function or activity of an organ in the body.
