Normally rollators have two brake levers, both of which must be operated simultaneously. A person with hemiplegia (e.g. after a stroke), rheumatism or arthritis may have limited hand function on one side of the body. This is where a one-hand brake can help: Thanks to the special system consisting of a set of cables, it is sufficient to brake on one side - whether left or right. Safe and effective braking is thus also possible with one hand.
