Wireless Surface EMG Modules | Data Acquisition
Physiological
data acquisition systems offer many options for recording surface EMG, needle
EMG, and fine wire EMG. General muscle activity and fatigue can be determined
by recording and analyzing surface EMG data from major muscle groups.
Correlate
EMG activity with data from other sources including force plates, goniometers,
and motion analysis equipment. Analysis software
tools, including spike counting, muscle activation location, and frequency
analysis allow for post-acquisition surface EMG data interpretation. Results of
EMG recordings can be output as graph channels for easy data visualization, or
can be in numerical format in summary tables or spreadsheets. Data can then be
used for further statistical analysis.
EMG Analysis | Biomechanics
Biomechanics
research has never been easier thanks to powerful new data acquisition and
analysis tools. Perform real-time calculations and post-data acquisition
analysis on a variety of biomechanical and physiological data.
Simultaneously
acquire up to 16 channels of biomechanics and/or gait-specific data. An example
setup could incorporate two channels of heel/toe
strike timing, ten channels of EMG signals, and
four channels of goniometry data — however combinations are virtually endless.
Record sit-and-reach tests, range of motion evaluations, muscle balance
assessments and more.
Real-time
event markers allow researchers to log important events in the data and also
include comments that can be written during or post acquisition.
After
recording, choose an automated
analysis package to interpret and score the biomechanics data. For example,
automated EMG
analysis allows for a variety of automated functions including deriving
integrated EMG, root mean square (RMS) EMG, locating muscle activation, full
frequency and power analysis, and much more.
