Multiple Sclerosis can affect our bodies in a number of ways and weaken the muscles. It can also weaken the neurological pathways, which means that it is often difficult to carry out a certain task because messages that pass along the damaged nerve become delayed or blocked. This is what happened to my left arm over 2 and a half years ago and although I had physiotherapy with a specialist at the hospital, we discussed that I could do the shown techniques at home (plus it was all through covid and it was better to stay away from hospital settings at that time).
