Vibromyography (VMG) has distinct benefits over EMG in that the recordings much more accurately reflect absolute muscle effort up to 100% maximum voluntary contraction. Correspondingly, VMG can be used to both evaluate muscle changes over time in a given individual or to compare between two populations the muscle effort required to complete a specific task. […]

To date it has been difficult to characterize the length-tension curve for a specific muscle. However, recent developments in the application of vibromyographic (VMG) technology to assess muscle effort permit an accurate determination of length-tension curve, thereby permitting accurate diagnosis and rehabilitation of muscle. Click for the full applicaton note Using Vibromyography to obtain length-tension curves […]

A new application note for MRI Smart Amplifiers addresses the recording of real-time physiological data, from a human subject, during fMRI. These MRI Smart Amplifiers are designed differently than BIOPAC’s standard amplifier modules. MRI-specific amplifier modules feature internal circuitry which is designed to minimize MRI artifact (to the maximum extent possible) while still best preserving […]

Pulse Wave Analysis in small rodents Researchers at the R&D lab of the pharma company NicOx in Italy recently presented results from their study of PWA and Augmentation Index (AIx) in rats. A presentation was made at the last European meeting on Hypertension. “Beneficial Effect of Nitric Oxide on Large Arteries in Hypertensive Rats”. C […]

BIOPAC Automated Electrodermal Activity Scoring Measuring Behavior Conference Tutorial: Thursday, Aug. 26 at 10:00 a.m. In this tutorial, an introduction into the physiological basis for electrodermal activity (EDA) recordings will be given. The entire data analysis process for EDA (Electrodermal Activity) recordings using the AcqKnowledge software will be explained in detail.The tutorial will be based […]

BIOPAC's line of MRI-compatible data acquisition equipment now includes MRI Smart Amplifiers for ECG, EDA, EEG, EMG, and PPG signals. MRI Smart Amplifiers incorporate advanced signal processing circuitry which removes spurious MRI artifact from the source physiological data. Signal processors are able to distinguish between physiological signal and MRI artifact as manifested by gradient switching during […]

Sport Science brings in former UFC Lightweight champion B.J. Penn to demonstrate the impact of the rear-naked choke on host John Brenkus and uses the fNIR System from BIOPAC to measure oxygen supply to the frontal cortex during the exercise; EEG and heart rate were also recorded. John’s heart rate drops from 124 to 80, respiration […]
