16 Comparative Treatments

i Description/ name of comparative treatments

The Contralaterally Controlled Functional Electrical Stimulation (CCFES) is a system, which detects and converts a control signal from the healthy side of the body to regulate the intensity of electrical stimulation delivered to the corresponding muscles of the paretic limb on the affected side of the body.
Our collaborator, the ASTRI group has developed a similar system named the Microelectronic Neural Bridge (MNB). MNB senses the electromyography (EMG) signal of a particular group of muscles. Such signal is channeled to a processor, which generates electrical stimulation to the corresponding muscles in the paretic limb, in much the same way the CCFES system does. Training the paretic limb for 2 weeks.
