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. One major benefit of being able to compare results between muscles and between subjects is the ability to perform muscle balance assessments.

VMG systems use sensitive MEMS accelerometers, about the size of a quarter, and advanced signal analysis algorithms to monitor muscle vibration. The technique allows researchers to study muscle performance and strength balance.

Accelerometers are secured over the muscle belly* and record the small vibrations that occur when the muscle is activated. AcqKnowledge software uses wavelet packet analysis to extract the vibrational components that correlate with the effort generated by the muscle being studied. AcqKnowledge includes automated VMG analysis filters to simplify the analysis process.

Complete systems for muscle monitoring using Vibromyography include an MP data acquisition and analysis system with VMG analysis filters and TSD250 VMG transducers. Available as 2- or 4-channel VMG Systems—add transducers to extend up to 16 channels.
