Yoga and stroke rehabilitation

I started a yoga class three weeks ago. It requires watching the demonstration and trying to figure out what parts I can do and what I have to modify. I have never taken a yoga class before so the names and positions are new to me. The first week was up and down positions including downward dog, Since I can't flatten my left hand at all and the left elbow collaspes I would do a 3-point version. Rather unstable. The instructor finally told me to change it to a low dog. Some of the lying down positions I concentrate on relaxing the left arm so it will lay on the floor. If I do any other movement like lifting my legs my bicep goes spastic and pulls my forearm perpendicular to the floor. Multitasking just is not possible. She is a former dancer so she makes movements flow into each other, I really slow it down, specially going up and down. It looks as ungraceful as hell.
