Do stick around, BBS, it's pretty nice here.
I've just begun using trekking poles as an alternative to a rollator. I have a long way to go but have already found it a huge relief to my shoulders and hands. My posture is improving and I find it far less fatiguing than even a cane.
My balance is extremely poor but since I started with the Bioness L300, it seems to be slightly improving and the poles add to that.
I'll be off for my hike in just a bit here.
