My solution is to use an L shaped table, siting at 45º in the internal angle of it, so each of my elbows rest on the table and not on the arms of the chair. Having the elbows more appart have a similar efect as rotating the wrist in an ergonomic keyboard. It also releases neck and back tension as I am forced to sit more straight. This is a thing basic for me. I couldn't sit in the standard way perpendicular to a table with my elbows in the chair arms for half an hour and not feel strain, but I've never seen this option discussed in any ergonomics guide ever.
