We are looking for a suitable surface emg kit to assessment motor activation patterns in normal and painful shoulders. We are especially interested in time of onset, muscle fatigue characteristics and so on.
we recently used the system from Cometa (http://www.cometasystems.com), the Gereonics miniturized electrodes (http://www.gereonics.com/biopotentialelectrodes.html) and the EMG Easy Report software (http://merlobioengineering.com/emg-easy-report/) to assess the motion pattern (onset/offset time and activity profile) of muscles that control the motion of the scapula (Picture attached) and to obtain normal reference data for shoulder and upper limb muscles during reaching movements.
Miniaturized electrode were used to prevent crosstalk and placed according to Basmajian & Blanc. Muscle onset was computed according to Merlo et al 2003, IEEE Trans. Biomed Eng.
I hope it can help.
I am the main author of the EMG Easy Report software, thus I have a conflict of interest to discolse.
