TECNALIA REHABILITATION

We undertake research in the field of rehabilitation devices for professionals dealing with the diagnosis, evaluation and management of people of any age with physical and/or cognitive impairment and disability. This area encompasses the diagnosis and treatment of patients with functional limitations. NEURO-REHABILITATION • Rehabilitation robotics and functional electrical stimulation for physical training and motor learning. • Tools to quantitatively assess the functional improvement. • Technologies allowing outpatient and home rehabilitation. • New methods for assessing motor and cognitive learning and training in terms of neuronal changes.

ORTHOPAEDIC REHABILITATION • Technologies that aim to aid recovery from musculoskeletal injuries, and minimize and/or compensate for any functional alterations. • Smart materials for support of function or recovery. • Biosignal sensing and feedback - Garments and Orthoses.

“TECNALIA has developed a technology based on functional electrical stimulation (FES) approach and using multichannel electrode arrays for paralysed muscle stimulation. The neuroprosthesis delivers electrical stimulation pulses to innervation pathways in order to replace the missing biological control signals. Movements are stimulated to perform motor functions like reaching, grasping or walking. FES neuroprostheses, like robotic devices, can be used in combination with a telerehabilitation platform for home use.”

limbs precision

Âż? FESArray is an advanced surface electrical stimulation technology featuring selective neuromuscular stimulation for functional electrical therapy and function compensation.

The FESArray is applied directly to the body surface - not implanted underneath the skin - which means no surgery is involved. It can be worn discreetly under most clothing. The main novelty of FESArray in comparison to existing stimulation systems is the implementation of unique multi-pad electrodes allowing for high selectivity in motor control, easy positioning, shaping of active electrode surfaces, so-called virtual electrodes, and the possibility of distributed stimulation. The technology provides a tool to the therapist and the patient for faster and easier optimal electrode positioning. The functional performance of the electrical stimulation is increased through improved muscle selectivity and less muscle fatigue due to distributed, asynchronous stimulation. Parameter adjustment can be done easily on the device by an intuitive user interface.

The exact location of stimulation points is adjusted by the user on a touch interface on the surface of the electrode garment. The electrode-skin interface is matched to the skin impedance for best selectivity and comfort.

A multi-layered structure comprises the FESArray contact pads, the multi-channel wiring and the garment orthosis.
