Applications
An Electromyography (EMG) use EMG electrodes to pick up the electromyographic signal directly from the skin surface or within the subjects muscle using disposable fine-wire electrodes. Both are typically expressed in SI units micro Volt (mv). The Bioforcen-TB0810 model Biomechanics EMG can be used for biomechanics, engineering, medical research, orthopedics, rehabilitation evaluation, prosthetics, and general industrial uses. Specific uses include gait analysis, testing or stability analysis, neurological analysis, prosthetics fitting, athletic performance, shoe design, and force, power, and work studies.
Description
The EMG signal from each muscle is individually pre-amplified, band-pass filtered prior to digitization, and then converted to a binary sample for each of the channels. These operations are all performed directly in the subject back-pack to maximize signal quality. The binary information is then sent from the subject back-pack unit, via a single lightweight cable or wireless, to the desktop unit where it checked for transmission accuracy and then converted to an analog signal suitable for almost any analog data recording system. The desktop unit provides full electrical safety isolation for the subject.
AMPLIFICATION
The Bioforcen-TB0810 model Biomechanics EMG provides excitation and amplification for multiple channels in one convenient package. These amplifiers process the transducer signals and provide outputs suitable for an A/D converter so that the data can be stored and processed by a computer.
CALIBRATION
Each platform is inspected and tested in JUNE calibration facility. The calibration procedure provides a detailed sensitivity matrix and a complete test of all system components, including the amplifier and the connecting cable if ordered together.
SOFTWARE
Automated data collection and reduction requires a computer and software. Bioforcen-Analysis, Bioforcen-software package, is specifically designed for biomechanics .
