Features
-
Experiment Workflows
Build the workflow for your recording session out of configurable data acquisition tasks, each tailored for a specific part of an experiment. Templates are included for acquiring MVC, displaying normalized or raw data as feedback, or tracking a predefined trajectory.
-
Integrated Database
Allow EMGworks to manage your data with subjects, workflows, and data files stored in a searchable relational database. Tagging, filtering, and grouping options allows intelligent searching of data across experiments to build up data sets for comparative studies, or for tracking subject progress.
-
Visual Trajectory Editor
Define custom trajectories for biofeedback tracking tasks. Among others, cyclical and ramp trajectories can be created, and feedback signals normalized against an MVC or a fixed force level. Workflow tasks are provided for using load cells or EMG signals as biofeedback guides.
-
Anatomical Maps
Illustrations showing muscle name and location are integrated into the software to ease sensor placement and promote muscle familiarity.
-
Flexible Voice Prompting
Fully customizable text prompting for the subject and experimenter. Use pre-recorded sounds or voice synthesis from text you enter.
-
Signal Exploration
Explore collected data without pausing data acquisition. Place markers on events in the data, and use cursors to obtain a quick assessment of signal characteristics (including RMS and peak-to-peak).
-
Multi-point Calibration
An integrated calibration wizard simplifies biosensor calibrations. The calibration allows the mapping of sensors with a nonlinear response to their true units, by allowing the definition of more than two calibration points. Calibration information can be entered directly from a specification sheet, or measurements can be taken from the sensor at known positions as a part of the wizard.

EMGscript™
EMGworks® Analysis now includes the power of a script interpreter and a library of scripts for signal processing, from standard data processing to complex custom applications. EMGscript™ is a powerful data analysis language for bringing your vision to reality. With it, you can create custom calculations, design unique analysis processes, and control every parameter of any calculation. Every EMGscript™ can be run from a user-friendly graphical interface. Prepackaged scripts and even scripts you have created in your lab will automatically be accessible through the same graphical interface . EMGscript™ removes the boundaries of traditional data analysis tools and gives control back to the researcher. |

 Workflow Templates
The templates below are provided in the Workflow Designer as building blocks to construct your experiment. Each has customized options for performing a specific data acquisition task. The prompting, triggering, acquisition time, and number of repetitions can be individually controlled for each instance of a template in your experiment workflow.
Show the output of feedback sensors (Force or EMG) in the configuration and display one sensor to the subject. Data are not saved.
Collect a maximum voluntary contraction from a force sensor which may be used to normalize subsequent data. The sensor’s offset is automatically computed from the quiescent period at the start of data collection. The number of MVC attempts, attempt time, and rest time are all configurable. The subject will be presented with bar feedback as well as textual and audio prompts to indicate when they should contract.
Similar to MVC (Force), but uses realtime RMS feedback from an EMG sensor to estimate the force produced.
For usage when force feedback will be used with an isometric contraction against a fixed, known load for all subjects (such as attempting to lift a fixed weight).
Provides a trajectory for the subject to track, where the effort exerted is displayed as a trace normalized by the MVC. Allows arbitrary sensors to be displayed for the operator. For the subject, multiple feedback channels (which may be independently normalized based on the output of a MVC task) can be shown.
The same options as multiple tracking paradigm, but displays the feedback to the subject as bars instead of traces. Based on the sensor type, real-time filters are used to process the data for feedback presentation if needed. It may also be used to collect data without feedback, simply by not selecting any feedback channels.
A simple data acquisition task which displays signals to the operator (like an oscilloscope) and stores the data.
Measures the offset of each channel used in the test configuration. The channel configuration may be adjusted to compensate for the offset in future data collection during the current test run, or the channel offsets may be set to zero (default). Data are not saved.
Automatically transfers the data collected during the experiment to EMGworks Analysis for processing and analysis upon completion of the experiment.
