Active Release Techniques

I searched this site and found nothing about this.

I have an ailing shoulder and finger (tendonitis and motorcycle accident, adhesion from weightlifting plus bad genetics). I have heard nothing but good things about this treatment, and I would like to hear about any experiences with this treatment. This seems to be my only option, considering my current personal situation and I am getting a little bit excited about this idea.

Is this truly as legit as it’s made out to be? Did it work for you or any people you know? What have you heard about it?
