> Is there a better design than a frame? there are articulated frames that you move one side after the other. The idea is to keep the arm movement which is natural and helps with walking but they are not terribly stable compared to the Ustep. 2 walking sticks are best. The hiking type John used are just like ski poles, with a good handle and I think the grip is far better than ´normal´ walking sticks. maryse ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
