As we’re working towards the launch of our Stil Orthosis over the summer, it is particularly nice that the Delft University of Technology puts us in the spotlight.

TU Delft Campus interviewed our founder IJsbrand de Lange about his journey from the initial idea to building an orthosis that can stabilize the hands of people with a tremor, and help them to lead a normal life again.

Testing at Reinier de Graaf Gasthuis

According to IJsbrand, Delft is a warm bath for entrepreneurs, because everything you need is within reach: the knowledge and test facilities of the university, the Reinier de Graaf Gasthuis as a regional hospital and two academic hospitals a short distance away (Rotterdam and Leiden). In addition, TU Delft Campus is bursting with collaboration opportunities.


Stil tested their orthosis the last couple of years at Reinier de Graaf Gasthuis in Delft, where more medical innovations from Delft are tested. They recently successfully validated the operation of their technology.


“In the neurology department, people with Essential Tremor have worn the orthosis and given us crucial feedback. On how it works, but also on wearing comfort and appearance,” says IJsbrand.
For example, the high-gloss white prototype was found to look too clinical, so it is now matt black for an unobtrusive look that fits better with clothing. They also wanted a lighter and more compact orthosis to wear discreetly under their clothes. That was not possible with the larger prototype, but now it is with the further developed version.

The patient was central during the two development years, and they all expressed a clear wish: to live a normal life again. This year they will be first in line: after having been on a waiting list for quite some time, the anti-tremor orthosis can be tried in autumn. The price will be comparable to that of an entry-level electric bicycle. Eventually, it should be reimbursed by health insurance companies.
