Procedure

Microelectronic Neural Bridge Training

2 weeks

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.

1. Aged 18 or above
2. Within 6 months post stroke (both ischemic and hemorrhagic)
3. Manual muscle grade of 3 or less for finger extensors
4. Functional hand opening in response to electrical stimulation
5. Cognitively capable of using the MNB system as instructed

1. Had intramuscular botulinum toxin injections in any upper-extremity muscle within 3 months before enrollment or at any time during the study
2. Apraxic
3. Had uncompensated hemineglect
4. Had uncompensated hemianopsia
5. Had pacemaker in situ
6. Had metal implants in situ
7. Had recent upper limb fractures
