Although originally a brand name, “rollator” has become a generic term in many countries for a wheeled walker (often 4, two front and two rear), and is also the most common type of walker.
The rollator usually consists of a frame with three or four large wheels, a handlebar and often a built-in seat, which allows the user to stop to rest when necessary.
Walkers are often equipped with a trolley, usually in the front, which can be used to store items such as a shopping bag.
Rollers are generally more sophisticated than conventional walkers with wheels. In these more modern aids, in addition to specific height adjustment systems, there are in fact some knobs, called push knobs with a handle made of soft materials (e.g. rubber) in order to facilitate the grip, making it safer and more comfortable. These grip and push knobs are adjustable in height (generally within twenty centimetres) to suit the patient’s needs.
They are also equipped with a brake lever, positioned immediately below the handles, which has both a safety function during walking (which can be used to stop the rollator immediately) and a parking function when the device is used by the user as a support that allows him to sit safely. The most technological walkers may have a seating system, which varies from manufacturer to manufacturer, generally consisting of a folding seat made of a very resistant plastic material, which can be used by the user when the walker has become excessively strenuous and requires a break and rest.
Certain models can also be fitted with a strap, which acts as a backrest. The sturdiness of the walkers is often superior to that of conventional walkers.
The brakes can also be used to facilitate manoeuvring with the rollator: by braking one side, while rotating, the rollator automatically turns to that side allowing a very tight turning radius.
In the more modern rollers, the use of large front and rear wheels is preferred (compared to the small wheels of the first walkers), as this choice seems to make it easier to overcome certain obstacles that can be found on the road, as well as steps, protruding manholes, sidewalks or curbs, all in high safety. There are also models equipped with internal suspensions, always aimed at easy passage on uneven surfaces.
