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. […]

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 […]

The US national Naval Medical Research Center in Silver Springs, MD has published a report describing a method and setup for investigating the effects of blast waves (explosions) on the brain and central nervous system. The report compares the MPMS100A Micro Pressure System (Samba*) with high-sampling PCB sensors and justifies the use of the MPMS100A […]

A team of UCSB Media Arts and Technology (MAT) graduate students will present their end of year project at BIOPAC on Monday, June 7, 2010 at 12:15 PM. The project, which examines principles associated with traditional Chinese medicine, involved the extensive use of BIOPAC equipment and software. The students employed the Network Data Transfer facility offered with the […]

Ultra-thin optical fiber pressure transducers available from BIOPAC were evaluated excellent for measuring urethral pressure simultaneously with urinary flow rate and bladder pressure recordings in laboratory rodents. Urethral pressure recording is a valuable tool for obtaining information of the mechanisms in female rat micturition. For urethral pressure recording, the MPMS100A-2 System with TSD170 series micro […]

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.
