Rollators, walkers and walking frames are a support tool used by disabled and elderly for balance and support when walking. Unlike walking frames and four-wheeled walker with seat, rollators are more sophisticated devices but not more expensive. Rollators are well designed walking frames with wheels, breaks and a rest seat that can also be used to carry personal belongings, groceries, etc.
Walkers and rollators are a good supporting tool that is prescribed, often by an occupational therapist for rehabilitation from leg and back injuries. Wheeled walkers are perfect for this because they add torsional and vertical support to a rehabilitation patient or the elderly when walking with support.
