I have used Nordic Poles since just after diagnosis six years ago. I had no information from my neuro and di not see a Parkinson nurse for months but was sure the right exercise would so googled, discovered Nordic Walking good for neurological conditions such as PD and MS and was lucky enough to find a group where the instructor's father had young onset PD and he had some success with PWP's already. Unfortunately most groups go too fast for me now but my poles enable me to continue walking with ramblers groups 4/5 miles which I couldn't do without them. It giives the upper body a work out,, makes you stand upright, exercises the spine and lengthens the stride. Some local authorities run courses.
