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.
Video is a compelling addition to physiology experiments. Researchers need to understand and observe the behavior of the participant, identify problems during the experiment and get a general sense of behavior and how that behavior relates to the data. If data looks wrong or bad, video can help researchers figure out why.
Recent studies in Psychophysiology, EMG, ECG and PPG measurement utilizing BIOPAC software and hardware: Fight or Flight (Reflex Response Time) “Fight or flight” is a physiological response that occurs due to a perceived threat to survival. It can physiologically be observed through an increase in heart rate, respiratory rate, blood pressure, oxygen availability, and other mechanisms. In […]
HRV, EMG, and EEG studies using BIOPAC hardware and software include: DON’T STRESS Humans encounter various stressful situations everyday at work, home, and school. Such stress when experienced at high degrees and/or for a long duration of time could lead to cardiovascular diseases, cognitive dysfunctions, and psychological disorders. This study examined the validity of a novel physiological measurement […]
