The ability to noninvasively assess voluntary muscle effort has wide application in physiologic studies, sports and rehabilitation medicine, as well as movement science. Traditionally, surface electromyography (sEMG) has been used for such assessments, but sEMG has several significant limitations arising from the fact that an estimate of muscle mechanical effort is being obtained from an electrical potential measurement made at the skin surface. As a result, it can be difficult to compare recordings from different muscles on the same person, on the same muscle over a period of days or weeks, or between the same muscle on different individuals. In addition, muscle fatigue studies are difficult as EMG activity tends to increase with increasing fiber recruitment, even though muscle effort is decreasing.

This is one of many ADVANCED FEATURES for the selected Application. Scroll down for hardware options.
To overcome the limitations associated with using sEMG recordings to evaluate muscle effort, an increasing number of investigators have come to rely upon vibromyography (VMG), or the recording of muscle fiber vibrations, to estimate muscle effort levels2. The development of microelectromechanical (MEMS) accelerometers has contributed greatly to this transition as extremely sensitive, very low noise sensors are now available at reasonable cost. VMG can be used to evaluate muscle changes over time in a given individual or to compare between two populations the muscle effort required to complete a specific task. VMG transducers record vibration data received from microelectromechanical systems (MEMS) sensors and proprietary software. VMG provides a convenient means for assessing rehabilitation progress following sports injuries such as ACL tears due to its ability to be utilized under conditions which reflect the multi-segment, closed-chain activities associated with functional activities.
