Four-wheeled walking aids consist of a tubular frames with four wheels that have air-filled or solid rubber tyres. These walking aids are designed so that the user is always moving inside the four contact points to the floor of the legs. These walking aids have brake systems that work through Bowden cables that are activated by hand levers.

Some products include fixtures such as baskets for loading objects that can be transported together with the walking aid. These walking aids are foldable for easy transport and the grip handles are height adjustable to suit different patient sizes.

Indication
The users’ remaining walking ability must be enough for leaving the home to conduct normal daily activities and maintaining a social life without endangering themselves or others.
