Dear Neil and All,
After several months of perseverance I have successfully produced a custom eye blink & eyebrow switch, for a brain stem infarct patient, which mounts on a headband.  The optical sensor is a Sharp IS471F (RS564-396) and infra red emitter Sharp GL480 (RS577-538).  The prototype is reliable and is easily fitted by care workers. I will shortly be producing a PCB version.  I also looked at the Cyberlink system but considered that the EEG analysis may be affected by the patients injury.

Dear All,

Does anybody have some good ideas about reliable EMG sensing equipment used to create an on/off output, i.e. for switching. The device would need to easily set up by a non-technical person and as small as possible. Isolation of the patient electrically is of course paramount.

Devices we've tried in the past are listed below. We would now like to extend our possibilities.
ProComp from Though Technology, http://www.thoughttechnology.com
and Myo-electric from Aleph 1, http://www.aleph1.co.uk/bio/ds02.html

To give you some background we have various patients/clients with brain injuries such as Brain Stem Stroke that result in only eye movement or cheek movement and we want to use this movement functionally for as much communication independence as possible.

Thanks,
