Hi Carole, We went to a physio that deals with patients MSA balance issues.
He walks down a hallway straight line, turning head from side to side looking at walls Sits in a chair and turns his head from side to side but keeping his eyes on the same spot on the wall. Walks down the hallway one foot in front of the other ,have the wall near buy as this is a hard one to do for him, needs to have wall near by to slide hand along when gets overbalanced. Standing still near support has one foot right in front of other, heel to toe of other foot. Daily walking very important as well. My advise would be for your husband be assessed by a physio first. This has helped my hubby as he is walking far more confidently during the day. At night is another matter.
