Dear List Members,

Last week I submitted the following question to the list members:

"For our laboratory we are looking to purchase an EMG system to make
recordings from dynamic muscle studies, co-activation of the
quadriceps and hamstrings particularly. It will be looked at
alongside torque readings from an isokinetic dynamometer. Can anyone
recommend a good manufacturer of hardware and/or software for such a
use, preferably a UK-based company although not a pre-req? We have
contacted a few firms (Digitimer Ltd, Biopac Systems Inc) but any
information on what others are using successfully at present would be
helpful. Thanking you in advance for your help. As usual a summary of
replies will be posted for all to read."

----------------------------------------------------------------------

Following is a brief compilation of EMG systems that were recommended
(as I received so many responses only those mentioned a number of
times have been included and a list of those who responded would have
been very long - thank you all)

http://www.delsys.com have a uk distributor (Median Systems Ltd-01258
858999 - Richard Brown): widely used in UK.

Noraxon (Myo1400). Flexible, and mobile, and will play nicely with
isokinetic devices. http://www.noraxon.com/

Mega Electronics in Finland (www.meltd.fi) UK distributor is Cranlea
(Birmingham). Their email is info@cranlea.co.uk, tel. 0121-4720361
and fax. 0121-4726262. Contact person: Graham Barnickle.

http://www.grass-telefactor.com/ Grass EMG amplifiers (model P511 or
CP511 best-excellent research quality, Model P55 less expensive
alternative-good for most research and student labs). All these amps
are highly adjustable by the user (amplification level, high & low
pass filters etc).

For data acquisition: hardware (model 1401 A/D) and software (Spike2)
from Cambridge Electronic Design (in the UK) http://www.ced.co.uk.
The CED equipment is excellent in terms of capacity, flexibility and
easy to use. Support is excellent.
