BTS EMGenius

BTS EMGenius is software used to acquire, elaborate and report electromyography and footswitch signals, for the functional evaluation of gait cycles, by means of an automatic identification of the gait phases, or of movements such as "hand to mouth, "sit to stand", "hand flex-extension", "reaching", etc.

BTS EMGenius is useful for all clinical evaluations looking at muscular activity during motion, such as neurological and orthopedic pathologies, pharmacological therapies, evolutions of motor deficit, use in orthesis and rehabilitation.

Main features:

Visualization of raw data, on-off switch signals, reference cycle phases (i.e. during gait analysis the stance and swing phases will be shown with different colors which are selectable by the user, for right and left side).

Automatic extrapolation of temporal parameters of the defined cycle movement. The system allows graphical-numeric representations of the temporal sequences and of the phases (outlier).

Analysis of the mean and median cycle on temporal events selectable by the user.

Computation of the power spectrum (PSD), to have a qualitative control of the acquired data.

VIDEO synchronized with the signals: an excellent frame by frame visualization procedure has been implemented. It allows the user to scroll the video forwards and backwards, frame by frame, thanks to the pre-loading of the video data in the memory, without any limitations on the used CODEC characteristics. It is possible to choose the length of the video portion to be visualized and the temporal position inside the acquired trial.

Database to organize the data related to the patients and to the analysis sessions.

"butterworth" high-pass filter, of 2nd order, without phase delay.

Tools for the visualization operations: zoom right or left side selection, scroll.

Definition of visualization windows of user selectable length, to visualize a portion of the signal which is very useful in particular for holter acquisitions. It is possible to visualize the windows in respect to time or the number of cycles.

User defined threshold value, to include or discard cycles from the elaboration or from the temporal parameters computation (i.e. which cycles hold good in the gait parameters definition, or in the stride and stance phases duration computation).

Data report in Microsoft WORD format: during the elaboration procedure of EMG signals, the user can send to the report, with a mouse click, the BTS EMGenius working area content. Graphs dimension pre-defined layout, full-page, ½ and ¼ page, can be applied automatically. At the end of the elaboration procedure, the report can be visualized in Microsoft WORD with the ability to add notes and comments and print or export it in HTML or PDF format which allows for the sharing of information with other centers via the internet or by including the reports directly in electronic medical records.

Assessment and representation of the linear envelope of the signal: the algorithm applied includes the signal rectification and the low-pass filter application with cut frequency, by default, equal to 25Hz, but also user definable.

Input data format: TDF (BTS), EMG (BTS), MDX (BTS SMART-Analyzer), C3D (international standard format).

BTS EMGenius, software for BTS FREEEMG and BTS POCKETEMG is the most advanced diagnostic tool available today for the study of muscular activity in the functional evaluation of cycle movements.
