I do not know much about small kids or potty training, but my mother once told me that she pottytrained me by using a "signal voice": every time she put me on the potty chair, she said "urr urr", and gradually, every time a felt a need to go the potty chair, I said "urr urr" too
I've understood that this method made my potty training process quicker and easier than usually.

I just found a website about hemiplegic children, which among other things dealth with potty training a child with hemiplegia. There were some advice: the potty chair should be very stable, the toilet paper roll should be placed on the child's non-affected side, the child's pants should be easy to pull down (loose fitting elastic waist pants are said to be the best).
