I’ve only trained two clients who have disclosed to me that they have MS (one prior, one current) and have a relative who fought it for 30 years before it took her life. Both were pretty early on in the progression of their condition, still walking and actively exercising. Balance was / is a challenge for both, so the previous recommendations about MELT for proprioception are spot-on. Both clients feel increased proprioception from the foot treatment and one loves the rebalance sequence.
Heat is really hard. One client liked to work out outside, so we had to meet soon after sunrise for her to be comfortable.
Stress also has a big effect on the condition. Seeing its effect on the progression of my family member’s condition, I try to make working with me as low-stress as possible.
