At my physical therapy session this afternoon, the therapist hooked the electrical stimulation machine (or maybe it’s that he hooked up two machines) up to both my shoulder and my wrist. I could feel the series of small shocks to the shoulder. I couldn’t feel any shocks to my wrist, but my pointer finger started moving all by itself — I mean, without my trying to move it. Of course I know it was moving because that’s the whole idea of the electrical stimulation, but it looked and felt very strange.
