If a lower limb of yours has been fractured or just under-gone surgery, you might feel the need for a walker till you get back on your feet for good. This walker provides a larger base of support, and also has wheels which help in locomotion. By providing four points of contact the walking aid provides both additional support and a wider range of stable centre of gravity positioning. You can adjust the height as you use extra support to walk or stand. This definitely provides superior stability than a standard walking stick as it helps direct the load through the arms and the walking aid thus lowering impact and static forces transmitted through the affected limbs.
