VMG transducers with Sonostics BPS-II sensors and software algorithm are optimized for assessing voluntary muscle effort (Type IIb muscle fiber activity). The VMG BPS-II transducer includes band-pass filtering to eliminate most motion artifacts including physiologic tremor. The TSD250 is a sensitive accelerometer for use with BIOPAC Vibromyography Systems that use advanced signal analysis algorithms to monitor muscle vibration.
Accelerometers are secured over the muscle belly* and record the small vibrations that occur when the muscle is activated. The technique allows researchers to study muscle performance and strength balance.
VMG provides extremely reproducible results. The single sensor solution and the lack of skin preparation improve the reliability and reproducibility of muscle effort recordings between muscles and across subjects.

* Transducer can be secured with a variety of attachment methods (not included), such as double-sided adhesive tape, Ace® bandages and Nylatex® wraps (2.5” or 4” width suggested). Do not use excessive pressure in securing the transducers—snug enough not to move is adequate.
