Yesterday I tried playing Kaddish supine while using the black thermoplastic brace that my hand therapist made me. Tonight, I tried again with the thicker, stiffer white brace she also made. This one didn’t feel as good—it changes my hand’s position too much, so operating the valves feels awkward. It does help with preventing reinjury, which is its main purpose, but at too great a cost. The brace I tried yesterday was better.
