Here's what I did.

1. Measured my hand movement rate, 49. (Number of left/right repetitions 15 cm apart in one minute using my right, bad, hand.)

2. Lay on my back for 10 minutes with a thin pillow under my shoulders leaving my head tilted about 5 degrees "the wrong way".

3. Repeated hand movement test, 48.5.

(All done before taking my morning meds.)
