Hello, My step-daughter, who is a brand new physical therapist, says that of the following groups 1. Have good balance 2. Have some loss of balancing ability 3. Have very distinct loss of balance or even poor balance most falls occur with people in group #2, because they overestimate what they can do. Regarding walkers, I will be wanting an all-terrain walker when the time comes. ;^} Phil Tompkins age 60/dx 1990
