MCV – MAXIMUM VOLUNTARY CONTRACTION
The maximum voluntary contraction (MVC) will be calculated for each channel based on
the EMG maxima of your selected EMG signals.
The MVC acquisition can also be done in a separate signal acquisition session/file. This
can be useful to use when doing several signal acquisitions to ensure that the analysis of
all files and signals are done with the same reference values – the MVC values.
For this, start an acquisition and acquire your data which are being used as MVC values
for later analysis and save your acquisition. To use the MVC data from this acquisition in
another acquisition, click on the document icon in the CALCULATE FROM A FILE INSTEAD
field and select the OpenSignals (r)evolution file which contains the MVC signal data.
OpenSignals (r)evolution will then calculate the MVC value from the selected file.
Select OpenSignals (r)evolution file to calculate MVC values from file
Each channel’s MVC value are listed in the table below MAXIMUM VOLUNTARY
CONTRACTION.
MUSCLE ACTIVATION RESULTS
Click on the PROCESS button to process all signals according to the set configuration and
all found activations will be visualized in the processed channels (white frames).
To display all statistical information about one or two specific activations, click on the
first activation (left mouse button). The white frame turns into a blue frame and all
statistical information about this activation will be listed in the ACT X column of the
analysis results. When done, select the second activation of your choice by holding the
CTLR key of your keyboard and click on the activation (left mouse button). The white
frame turns into a green frame and all statistical information about this activation will be
listed in the ACT Y column of the analysis results.
The results table displays general information about the source of this signal (device &
channel) as well as general information about the duration and times of your acquisition.
All activation specific data is displayed below the given general information (e.g.,
activation number, duration).
