Ergonomics and Wrist Strain
Playing and jamming difficulties...HELP ME!
Given the wide variety of playing styles used on the dulcimer, I don't think there is any "proper form."
Noter-drone playing puts a very different stress on the wrist than any form of chording. Some people I have met who have hand issues find it the only way they can play. It is part of the reason I play almost exclusively in that style. I use a noter which is about 3/8 inch in diameter and about 6 inches long with my forefinger on top and the heal on the noter at my wrist.
You appear in your photo to be playing chords, so that probably won't helpyou at the present, but of your problem becomes severe, consider the noter-drone tradition before giving up.

That's when I click the gear and speed it up to 1.25 speed... what a Godsend!
