About this tool
Match a cane, crutches, walker, rollator or wheelchair to your support, balance, stamina and grip needs, with correct fitting height.
The Mobility Aid Selection Guide ranks walking sticks, quad canes, forearm crutches, pick-up frames, two-wheeled walkers, rollators, knee walkers and wheelchairs against one person's needs, because support, stability, portability and manoeuvrability trade off against each other rather than improving together. It scores each option on the weight relief it gives, the base of support it adds, the hand strength it demands and how it behaves indoors, outdoors and on stairs. It also gives the standard fitting rule: the handgrip should sit level with the wrist crease when standing with arms relaxed, putting the elbow at 15 to 20 degrees of bend.

Each aid lists what it gives up as well as what it gives — support usually costs manoeuvrability and portability.
Answers about stairs, carrying shopping, hand strength and memory change the ranking, not just the support level.
The wrist-crease rule and a height-derived starting range mean the aid is set up as well as chosen.
A walking stick suits mild unsteadiness and gives only about a quarter of body weight relief. A pick-up frame or two-wheeled walker gives the most stability and suits someone unsteady on both legs indoors. A four-wheeled rollator suits someone whose main limit is stamina rather than balance, because it rolls continuously, carries shopping and has a seat — but it can roll away if leaned on without the brakes.
Stand upright in your usual shoes with your arms hanging relaxed. The top of the handle should be level with the crease of your wrist, which puts your elbow at about 15 to 20 degrees of bend when you use it. That lands near half your standing height, so a 165 cm person is usually around 79 to 86 cm, but the wrist-crease check is what settles it.
The hand opposite the weaker or painful leg. Moving the stick forward at the same time as the weaker leg reproduces the natural arm-swing pattern and shifts load away from that side. Holding it on the same side as the bad leg narrows your base and does far less for the joint you are trying to unload.
It needs care. A rollator depends on remembering to lock both brakes before sitting and on not leaning on it while it is free to roll, so a two-wheeled walker, whose rear feet grip the floor under load, is often safer when memory or judgement is unreliable. An occupational therapist assessment is worth requesting rather than guessing.
