The day InnoRehab came to iol, he had a specific idea in mind: to design a quadripod cane with wheels to facilitate walking re-education for people who have suffered a stroke. A long-term observation period at CHN William Lennox had already made it possible to carry out tests on the basis of cobbled together prototypes to validate the principle.

iol was then responsible for transforming this tool into an ergonomic, design, industrializable and above all commercially viable medical device.
