I'm not aware of any studies on muscle spasm. Sure, relieving spasm could relieve headache, but I can't perceive a mechanism for acupuncture relieving the spasm.
The explanations I've heard are along the lines of either stimulating the body to initiate the release of pain-relieving hormones (or something), or that there is a neurological reaction that causes the muscles to relax (or something). Like I said, very hand-waving, but then I'll confess to not knowing much about medicine anyway.
I don't know if anyone has done much in the way of 'proper' studies on this but I do know it is a fairly common method employed by physiotherapists to complement other treatments. (Chiropractors as well if you think that counts for anything.
