Potential

Versive aims to revolutionise manual wheelchair mobility with steering-by-leaning. This patented principle eliminates the need for breaking to control direction enhancing propulsion efficiency, reducing strain on users’ shoulders, and promoting health and independence.

Project Description

Manual wheelchair propulsion is inefficient and causes shoulder problems in almost all long-term users. The inefficiency largely stems from a fundamental flaw in wheelchair design: users constantly need both hands for propulsion and are forced to spend up to one-third of their energy on active braking – simply to control their direction. This not only results in energy loss but is a significant healthcare hazard, impractical, and frustrating.

Versive addresses these adverse conditions with an innovative steering-by-leaning system that allows users to control direction without braking. Instead, users steer with their upper body: leaning to one side to turn and sitting upright to move straight. By eliminating the need for braking for directional control, propulsion becomes up to twice as efficient and significantly reduces strain on the shoulders. The system also enables easy one-handed manoeuvering, allowing users to carry or interact with objects while moving. Many testers describe the experience as effortless and intuitive, even comparable to “the dream of flying.”

Versive is advancing towards clinical validation and certification. Key milestones include the design and manufacturing of steering-by-leaning wheelchairs for clinical trials and securing the CE-mark for approval. Simultaneously, the team is working on establishing reimbursement pathways through disability and healthcare insurances to ensure broad accessibility. Versive is set to redefine manual mobility – making wheelchair propulsion healthier, more efficient, and more enjoyable for millions worldwide.
