  • Free software updates.
  • Record multiple channels of EMG, ECG, EOG simultaneously from a single subject.
  • EMG analysis included.

The RS-WEMGx system includes:

    • IX-RA-834 Recorder : with 4 iWire inputs
    • LabScribe Recording and Analysis Software for Macintosh or Windows PC
    • Disposable EMG electrodes ( pack of 50)

Add upto 4  iWireR-B2A: 2 Channel ECG/EMG with Accelerometer sensors to create your system.


Kinesiology is the study of human and nonhuman animal-body movements, performance, and function by applying the sciences of biomechanics, anatomy, physiology, psychology, and neuroscience. When studying kinesiology,  surface electromyography  (sEMG or Surface EMG) is the measurement of choice.  The IX-BIOx enables 4 channels of EMG recordings, or a combination of EMG and ECG recordings.

EMG analysis using LabScribe


ECG signals can also be recorded.  Measuring 2 channels of ECG, Lead I and Lead II allows LabScribe software to calculate Lead III, aVR, aVF and aVL .  EMG signals can be measured at the same time as the ECG signals.
