VMG Software License and TSD250A Transducer
Part #: VMG160PACK-W, VMG160PACK-M, VMG36RPACK-W, VMG36RPACK-M

This pack includes one TSD250A VMG transducer and AcqKnowledge software VMG License for use with an MP160 or MP36R data acquisition system running current release software. VMG software is optimized for the TSD250A and BIOPAC will not support or guarantee the performance of third-party transducers. The pack provides sensitive microelectromechanical (MEMS) accelerometers and advanced signal analysis algorithms to monitor muscle vibration. The technique allows researchers to study muscle performance and strength balance.

VMG Benefits

  • Ability to perform muscle balance assessments
  • Improved reproducibility between muscles and individuals
  • Convenient setup
  • Reduced setup time
  • Improved subject comfort
  • No electrodes
  • No skin preparation
Interface
MP36R: direct connection
MP160: via DA100C + TCI114 (not included with this pack)
This licensed feature add-on requires current release AcqKnowledge software. Check version details in the software “About” dialog and see upgrade options if necessary.

Compatibility


AcqKnowledge software uses wavelet packet analysis to extract the vibrational components that correlate with the effort generated by the muscle being studied. AcqKnowledge includes automated VMG analysis filters to simplify the analysis process.

VMG provides extremely reproducible results. The single sensor solution and the lack of skin preparation improve the reliability and reproducibility of muscle effort recordings between muscles and across subjects.
  • When comparing multiple subjects, identical transducers should be used. Results recorded with a TSD250A may not be directly comparable to data from older TSD250 and TSD251 transducers.

The accelerometers are secured over the muscle belly and record the small vibrations that occur when the muscle is activated. Transducer can be secured with a variety of attachment methods (not included), such as double-sided adhesive tape, Ace® bandages and Nylatex® wraps (2.5” or 4” width suggested). Do not use excessive pressure in securing the transducers—snug enough not to move is adequate.
