Hi fellow Ozzie,
In regards to your question, it really depends on what you mean but there are issues specifically to do with your hands......grip strength, finger pinch strength, weakness, hand eye coordination and Intention tremor off the top of my head are all very common.
Intention tremor is suppose to be the most disabling form of tremor pwMS experience, it's more pronounced during physical movement, so basically the tremor gets worse the closer your hand comes to an object or task so when you reach for something your hand may miss your intended target, over shoot, knock things over etc
Hope that helps.........JJ
ps unfortunately i can't come along on one of your nightly walks because i'm in Vic, i only know of two other Ozzie community members here, one's in SA and the other is in WA sorry, you could try contacting the QLD MS society to see if they can help you start off a walking group in your area.
