This research is being done for two reasons. The first reason is to test a set of special needles called double-blinded acupuncture needles to give acupuncture treatments (one is a real needle and the other is a fake needle). The second reason is to develop a protocol (checklist) that will be used in this and future studies, and to identify and resolve any procedural problems. The protocol will be first tested by the principal investigator who is also an acupuncturist. The investigator will perform acupuncture using the protocol, if necessary change the protocol, and then teach a second acupuncturist using the modified protocol how to use the double-blinded acupuncture needles.
