I found the best information at EPFL's web. ( http://biorob.epfl.ch/cms/page-36366.html )
They work with an italian research institute ( http://www-arts.sssup.it/tiki/tiki-index.php?page=robotics+for+neurorehabilitation ).
The method is the CPG ( Central Pattern Generators )
"Using CPG to control exoskeletons Exoskeletons are particular rehabilitation robots that are worn like an outer shell of the body. In collaboration with the ARTS lab at Scuola Superiore Sant'Anna (Pisa, Italy), we developed an innovative control method for an elbow exoskeleton (the NEUROExos) based on adaptive Central Pattern Generators. Conceptually, the elbow moving back and forth (continuous flexion/extension) can be viewed as an oscillator. The adaptive CPG comes to synchronize with this oscillator, and is able to learn its amplitude and frequency. In turn, the adaptive CPG feeds back some torque to the user through the joint actuator, therefore providing movement assistance..."

I asked for information to a good friend and he gave me two intereseted links
http://www.me.utexas.edu/~reneu/res/gait.html
They use the Statistical method for gait prediction and the Human gait pattern database was collected in Korean Institute of Science and Technology"
The other one lab is the Center of intelligent mechatronics

It's interesting but I couldn't download the publications.

Furthermore, I found an webpage with and interesting state of art, but, it's of a year ago.

Finally, I found too a French lab where analyse the performance and the model of the gait
