FREEEMG docking station

Surface electromyography device with wireless probes for the dynamic analysis of muscle activity.

FREEEMG is a 4G technology device for surface  electromyography (EMG) analysis. Signal accuracy, absence of wires, lightness and reduced size of the probes are features which enables users to perform analyses of any type of movement, for each body part, without altering the natural movement of the analyzed subject.

Excellent performance

Thanks to our wireless miniaturized probes even the weakest signals will be detected and accurately captured. The system communicates with a PC through the supplied USB receivers and can manage up to 20 probes simultaneously.
Each probe is equipped with internal memory to ensure uninterrupted recording in case of temporary connection loss and to allow for acquisitions in wide spaces and open fields.

Practical and effective

For signal acquisition, the probes are directly attached to the pre-gelled electrodes, with no need for additional fastening: subject preparation has never been so quick.
The software analyzes the collected information and generates graphical results allowing for immediate comparison to normal classes.
A large variety of predefined analysis protocols allow for assessment of muscle activity during specific exercises.



More than 500 centers worldwide use our EMG device for the evaluation of:

  • Orthopedic and neurological disorders
  • Pharmacological treatments
  • Evolution of motor deficits
  • Use of orthotics
  • Rehabilitation follow-up
  • Athletic task optimization
