A spinal cord injury resulting in a lesion at the cervical level C5/6/7 or a stroke, may leave the hand paralyzed.
Our research has demonstrated that we can measure residual muscle activity and we can use it to control stimulation of same or nearby muscles. What we call myoelectrically controlled functional electrical stimulation, shortened as MeCFES. This stimulation consist of special electrical impulses, imitating the nervous system, that can be applied to paralyzed muscles to make them move again. These are commonly used techniques that have been known for decades.
What is special about this project is that we combine several techniques to provide an easily applicable device that can help in improving the hand.

The specific use will depend on the kind of neurological insult, and the specific needs of the user.
Schematic drawing

This device, Libermano, will look like two open shells that close around the forearm. Technically it combines highly sophisticated electronic circuits (the MeCFES) into an elegant design (an electrode applicator, housing the MeCFES).

To put it on the user will put the bare forearm into the Libermano. A semiautomatic closing mechanism will apply electrodes in predetermined spots and the device will be ready to use. If the user has special requirements for the day she/he will be able to change settings or programme of the Libermano using his smartphone or tablet.

As this device is using non invasive techniques no surgical or other special interventions are required and using this kind of system will incur nearly no risks (see Precautions and Disclaimer)
