A new leaning wheelchair design from ETH Zurich researchers Reto Togni and Stefan Villiger promises to revolutionize how manual wheelchair users navigate everyday environments. Addressing the physical strain often experienced while steering, particularly on sloped surfaces, this innovative leaning wheelchair significantly reduces energy demands and minimizes user injury risks.
Traditional wheelchairs require constant steering corrections, straining shoulders and increasing the risk of long-term injury. Togni and Villiger’s prototype addresses these challenges using a “steering mode” where the front wheels lock into a straight position. Users can simply lean to steer instead of using their hands for constant adjustments, as the backrest is linked to the rear wheels. Testing showed that participants required much less energy and moved faster than with conventional wheelchairs, defying expectations that higher speeds would demand more effort.
Additional health benefits include improved blood flow, relief from pressure marks, and a free hand for carrying items. Despite regulatory hurdles, the team aims for a market release by 2027, offering a user-centric approach to wheelchair mobility.
