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.
That VMG provides both an absolute and reproducible assessment of muscle effort permits both right/left comparisons within an individual, as well as the opportunity to track rehabilitation progress over time where left/right comparisons are inappropriate or not possible.
Vibromyography (VMG) has distinct benefits over dynamometry in that VMG recordings reproducibly reflect absolute muscle effort up to 100% of maximum voluntary contraction. Correspondingly, VMG can be used to simultaneously evaluate individual muscles (e.g. antagonistic muscle pairs) either over time or to identify left/right differences. This application note addresses how VMG can be used to assess quadriceps rehabilitation progress in a young adult male following ACL reconstruction.
Electrodermal Activity (EDA) is an objective index for understanding emotional states. Researchers measure EDA to gain insights on psychological or physiological response, leading them down the path of scientific discovery. Because EDA is so important to research, BIOPAC has created tools to optimize event-related EDA analysis. Topics include: how to identify skin conductance responses, convert stim events from E-Prime SuperLab, Presentation, Vizard, etc., into AcqKnowledge events that can used for analysis, and score skin conductance responses using the AcqKnowledge automated EDA analysis tool.
NIRS and CNAP—Pairing great tools for great data Cerebral hemoglobin concentration (blood mass in the brain) is frequently measured in the prefrontal cortex, and systemic arterial blood pressure is known to be a variable factor based on the hemoglobin concentration. A leg pressure cuff was used to constrict and release blood flow to create a […]
