We are doing this study to investigate the effects of acupuncture on chronic low back pain.
We are interested in learning about brain activity during pain. We plan to look at brain
activity at the beginning and the end of the study, after 6 sessions of acupuncture
treatment. You will be randomly assigned to one of two groups to receive either real or
Acupuncture has been used for many years to help relieve pain. However, it is not clear how
acupuncture works. Acupuncture may relieve pain by changing activity in the nervous system.
Some studies indicate that acupuncture may relieve the low back pain. However, we need more
research to see how well acupuncture works to relieve pain for people with this condition.
In this study, we will measure your brain activity before and after you do exercises to make
your back pain worse. We will also measure your brain activity while inflating a pressure
cuff device on your lower leg. We will measure this brain activity using a research tool
called functional MRI (fMRI). Functional MRI is a very fast MRI that uses radio waves and a
magnet, and allows the study investigators to look at changes in blood flow to different
parts of the brain when there are changes in brain activity.
