Human Computer Interfaces


Worldwide, more than 65 million amputees suffer from phantom limb pain and many of them give up the use of a myoelectric prosthesis because learning to use it is a long and complex process.

Rehabilitation is not only for amputees, but also for more than 10 million people each year who suffer from limb hemiplegia post stroke.

Current rehabilitation therapies have limitations and are not universally accepted. Surgery with risks for the patient is the least popular, drugs have side effects and follow-up in a rehabilitation centre does not offer the possibility of rehabilitation at home.


For the Myotact device, TAM was estimated at 225Bn€ worldwide by taking into account both upper and lower limb market.


Myotact is a medical device resulting from 3 years of research work by the Hybrid team of INCIA (Cognitive and Integrative Neurosciences Institute of Aquitaine).

It is therefore to enable easier, quicker and more effective rehabilitation of amputees and hemiplegic patients that we have developed the Myotact bracelet, which allows the acquisition of muscle activity (or EMG) coupled with vibro-tactile feedback (biofeedback) while translating this activity into virtual movements via an application.

A patent has been filed to protect our technology with CNRS and Bordeaux university


Promising studies on amputee patients have been carried out as well as several prototypes of the device.
