"The effects of a course of acupuncture treatment for patients with chronic pain do not seem to decrease importantly over 12 months. Patients can generally be reassured that treatment effects persist."
Two meta-analysis studies (considered highest level of scientific proof) found that following a course of acupuncture treatment, 85-90% of the pain-relieving effects of acupuncture lasted for over 12 months.
Acupuncture MRI studies show show that a course of acupuncture literally re-wires the brain and this has a lasting effect.
"We also found clear evidence that the effects of acupuncture persists over time with only a small decrease, approximately 15%, in treatment effect a 1 year."
