|32/64 compatible - this program runs on any 32-bit or 64-bit Windows operating system.|
An easy to use application that graphs your EMG data to produce printed reports of the EMG activity in seconds. The EMG Graphing application supports raw EMG and Rectified EMG output by Trial and Gait Cycle from C3D files as well as older formats (Vicon, BTS, Motion Analysis etc). It includes normal activity databases and features advanced signal filtering, calibration and event detection abilities.
EMG Graphing is the easiest EMG graphing software package available to the clinician and gait lab user. It reads EMG data directly from your file and displays the results without requiring any complicated configuration or setup. We support all C3D file formats as well as native file formats from B|T|S, Motion Analysis Corporation, and Vicon Motion Systems. EMG Graphing effortlessly delivers instant viewing and full color reports for the trial data as well as individual gait cycles while including many advanced data processing features.
Download the current version from this page - this release includes support for 32 and 64-bit systems running Windows Vista, Windows 7, Windows 8.1 and Windows 10. Administrative rights are only required during installation - the application can run at a standard user privelege level.
EMG Graphing Features
|An advanced version of the EMG Graphing program (EMG Analysis) is available that offers additional FFT based analysis facilities. These include windowed and filtered EMG envelopes, RMS processing, EMG activation level reports, Spectral and Power analyses, co-contraction and aliasing reports as well as enhanced data export facilities and audio facilities.|

- Saves all processed EMG data in C3D files for easy retrieval and exchange.
- Templates automatically identify muscle and calibration information when EMG files are opened.
- Print multiple and individual EMG Gait Cycle reports displaying the signal as raw or rectified EMG data.
- Automatic detection of gait cycles from event switch data, force plate and marker data, or C3D event data.
- Export processed EMG gait cycles to ASCII files to create Raw EMG and Rectified EMG files (Excel compatible).
- Direct interface to the MLS Report Generator for Presentation Standard Graphics suitable for posters and slides.
Buy it once, use it everywhere - the EMG Graphing application, like all Motion Lab Systems applications, is a site licensed application. The purchase of an EMG Graphing license allows multiple copies of the software to be used within the licensed environment, permitting its use on multiple computers, laptops etc., making it very easy to use in academic and research environments without any hardware access keys or restrictive licensing requirements.
EMG Trial Reports
Raw EMG Data - opening an EMG data file with EMG Graphing will display the raw, unprocessed data for each recorded EMG channel. The channels can be labeled with the individual muscle names, side and scaled at surface potential (microvolts). Heel contact and Toe-off is optionally indicated by vertical lines on each plot with user selected color coded of the EMG data according to limb side. Once this information is entered, the EMG Graphing will store it in the C3D file as part of the data record as that it will always be available whenever anyone opens the file.
Rectified EMG Data - the EMG data can also be plotted and printed as rectified EMG. The EMG Graphing program offers the user complete control over the size of both the displayed image at all times. Data displayed on the screen can be previewed before sending it to the printer to allow the user to optimize the printed output - EMG trial reports can be compressed onto a single page or printed out in full over several pages.
Envelope EMG Data - the EMG Graphing program supports the display of enveloped EMG data for trial reports, displaying the complete enveloped gait cycle as enveloped data across all EMG channels. Individual gait cycle envelope reports are not supported by EMG Graphing - these analysis reports are available in the full EMG Analysis version of the program, however the entire trial can be printed as a single display showing the relationships between the individual muscle contractions.
All three trial display options offer the optional display of normal EMG activity bars underneath the subjects EMG records together with gait cycle events shown as heel strike (solid lines) and toe-off (dotted lines), indicating the stance and swing phases of gait. Each EMG channel can be labeled with side, a label and muscle name together with either the calibrated EMG levels (skin surface or intramuscularly), or the actual recorded signal levels in volts.
EMG Graphing reports
The EMG Graphing program can generate a gait cycle graph of raw EMG for each recorded EMG channel. Graphs can be scaled by %, or surface potential (microvolts) and display full heel contract to hell contact data with swing and stance phases of gait indicated. "Normal" EMG activity bars can be displayed and printed and each EMG graph labeled with a the muscle name. The muscle names and activity bars are fully configurable by the user and can be edited translated into any language. The EMG Graphing program allows the user to define individual normal activity and create a number of individually named activity profiles for different age groups and EMG protocols. EMG Graphing is supplied with sample normal activity profiles and can be downloaded and run as an evaluation version on any Windows PC.
In addition to the raw gait cycle EMG Graphs, EMG Graphing can also display the EMG data as a rectified signal. The graph below illustrates this and, in addition, is scaled in microvolts at skin surface as a result of a calibration operation. EMG Graphing supports EMG level calibration via built-in sources (available on most Motion Lab Systems EMG systems), or via an external source if your EMG system does not include calibration facilities.
"Normal" EMG activity bars may be displayed and printed and each EMG graph assigned a muscle name. The muscle names and activity bars are fully configurable by the user and can be edited or translated into any language. The EMG Graphing program allows the user to define individual normal activity and create a number of individually named activity profiles for different age groups and EMG protocols. EMG Graphing is supplied with normal adult and age matched children's activity profiles from documented sources
Each EMG graph can be displayed and printed in a user-selected color to indicate the limb (Left/Right) that is assigned to a specific EMG channel. These colors are used in both the screen displays and the printed output. The results of the analysis (both raw gait cycle and rectified gait cycle data) can be exported to Excel compatible ASCII text files, scaled by maximal effort, manual muscle test or skin surface levels.
