Stroke rehab while sitting in a chair

I sit in a scandinavian recliner while watching TV or reading. I grasp the left armrest with my hemiparetic left hand and try to keep it there while I cross my legs. This ends up failing most of the time. While just sitting there I try to just relax my left arm/hand so it lays comfortably on the armrest. As you can see from the arrows in these pictures the wrist spasticity prevents the arm from laying down flat. This is obviously not a useful attempt at do-it-yourself therapy because there is no functional use that will ever be gained by succeeding at this.
