FREEEMG docking station

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

FREEEMG is a 4G technology device for surface EMG analysis. Signal accuracy, absence of wires, lightness and reduced size of the probes are the features which enable us to perform analyses of any type of movement, for each body part, without altering in any way the motor gesture 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 a supplied USB receiver and can manage up to 20 probes simultaneously.
Each probe is equipped with internal memory to ensure uninterrupted recording in case of temporary internet connection loss.

Practical and effective

In order to get the signal, the probes will be directly hooked to the pre-gelled electrodes, with no need of additional fastening: subject preparation has never been so quick.
The software elaborates the collected information and generates graphical results allowing the immediate comparison to the normal classes.
A large variety of predefined analysis protocols allow us to assess 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
  • Sporting gesture optimization

The protocol allows the evaluation of the motion strategy used by the patient in terms of muscle coordination and symmetry during walking.

Main features:

  • Spatio-temporal parameters
  • Symmetry Index
  • Walking Quality Index
  • Coactivation Index
  • Muscle activation timing

The protocol quantifies the muscular pre-activation timing of selected thigh muscles while the subject is performing a downfall movement before landing on one single foot.

Main features:

  • Timing of pre-activation
  • Comparison with reference values

The protocol allows the evaluation of flexion-relaxation phenomenon of the lumbar paraspinal muscles during a forward flexion movement of the trunk and while keeping this position for a short period of time.

Main features:

  • FRP: Flex-Relaxation Phenomenon Index
  • FRR: Flex-Relaxation Ratio Index

The protocol analyzes the activity of the main masticatory muscles and quantifies the neuromuscular balance during the dental occlusion.

Main features:

  • Occlusion indices
  • Finalizzazione del bite

The protocol allows the evaluation of the muscles behaviour during rehabilitation exercises performed on a bike.

Main features:

  • Muscle activation timing
  • Amplitude analysis
  • Symmetry Index

The protocol allows the evaluation of the motion strategy used by the subject in terms of muscle coordination during running.

Main features:

  • Run cycle analysis
  • Muscle activation timing
  • Amplitude analysis
