Re: Chiropractic: Active Release Technique
I've had about 4 ART treatments, and they didn't do a lot for me. The main reason for this is mostly due to my problems (muscular tension as opposed to muscular injury). My infraspinatus, teres major and teres minor tend to tighten up a lot.
The 2nd reason I think they didn't do a lot for me is because they were done by a chiropractor (a 5 minute treatment, repeat every week for the rest of your life).
It sounds to me like your problem is more of a nervous one than muscular. You might have pinched a nerve (perhap's a cervical nerve). From the articles I have read on ART, they can treat both nervous and muscular conditions, and work best in the case of injury (where there is adhesions between adjacent muscle layers or between muscles and nerves. The adhesions are usually caused by scar tissue resulting from injury.
My feelings on the most effective treatment is massage therapy followed by chiropractic treatment. My reasoning is the chiropractic treatment can realign joints, but if the surrounding muscles are tight, and biased, the joint will be pulled out of alignment in short order (why you have go back to the chiroproctor every week). The massage will make the muscles surrounding the joint looser and more supple, so they won't pull joints out of alignment so quickly.
But I agree with Glen, you should have your condition assessed by someone competent before putting too much weight in any one treatment.
