RE: Intelligent neuro-prosthetics – don´t count your chickens before they are hatched
- Andreas Otte, Professor, Laboratory of NeuroScience, Offenburg University, Germany
(28 March 2018)

In the last few years groundbreaking medical technology approaches have been reported to help patients who are not able to control or use their limbs or have lost one of their limbs (1–5). Are these approaches, which are often only feasible in an expensive experimental setting, desired? What are the needs, wishes and possibilities of amputees and spinal cord injured individuals? How can we transform high-tech approaches to low-tech solutions? Where are the simple and affordable solutions applicable for all people around the world?
The world’s fascination with intelligent neuro-prosthetics continues unabated. But, to proceed, we must learn to ask the patients even closer.
