BTS FREEEMG 300
BTS FREEEMG 300 stands for an improvement in the performance of the FREEEMG systems already appreciated by researchers and clinicians throughout the world. These practitioners need to be able to rely on a daily basis on a highly efficient system easy to configure and use, for differentiated clinical and researcher applications.
The probes amplify the EMG signals, digitize them and communicate with the compact and light receiving unit,, which can be either way worn by the patient, left on the table or held by the doctor.
The complete absence of wiring not only minimizes the patient distress during the preparation but also grant him full range of motion during the task without restrictions..
The probes variable geometry and the substantially reduced size and weight allow them to be used on any body segment and during all types of movement (walking, running, jumping, etc) on a variety of subjects without affecting in any way the motor pattern..
Thanks to the use of environmentally friendly rechargeable batteries several hours of data can be recorded.
BTS FREEEMG 300 is supplied with Myolab, the smart and easy to use software that BTS has developed for EMG signal acquisition, visualization, and a first level of processing.
BTS Myolab with its advanced analysis tools is the most flexible solution providing advanced analysis, including the localized muscle fatigue measurement and cyclic contractions computing.
As option, for advanced EMG software applications BTS also offers BTS EMGenius and BTS EMG-Analyzer.
BTS EMGenius is the applicative software for the functional evaluation of cycle movements (as in the gait, by means of an automatic identification of the gait phases), or of movements as “hand to mouth”, “sit to- stand”, “hand flex-extension”, “reaching”, etc.
BTS EMGenius provides a user friendly and intuitive interface: the operator immediately learns how to use the software achieving the highest productivity level for the lab.
BTS EMG-Analyzer is the most complete software solution for EMG signal analysis. Includes predefined templates for evaluations in clinic, sport and research field: jump, pliometry, gait, fatigue analysis, isokinetics, etc… It integrates also an editor to design elaboration protocols: the user can develop quickly and effectively customized elaboration protocols. Thanks to an innovative visual object interface, the mathematical analysis language is translated into graphical form.

Record of miniaturization
BTS FREEEMG 300 uses the best technology available today. Totally wireless, it integrates probes with active and variable geometry electrodes, weighing less then 9 grams.
Quicker Analysis and Increased Accuracy.
The total absence of cables makes for a quick patient setup. The lightweight probes are attached directly to the pre-gelled electrodes and do not require any additional fixing such as adhesive tape. The patient can move around freely.
Powerful and Comprehensive
16 electromyography channels, 2 footswitch channels covering up to 8 contact areas, and up to 4 electrogoniometers probes (each takes up 2 EMG channels).
16bit Accuracy
The sampling rate of up to 4 KHz and the 16 bit resolution give to the acquired signal the highest quality ever, providing “low noise” and the absence of movement artifacts.
On-board memory
The probes are equipped with a solid-state buffer memory to avoid loss of data that can happen due to problems with WiFi signal, or when the probes are simply out of range during the acquisition.
More than 5h of non-stop acquisition
The large autonomy and energy-saver battery insure a whole day recording. Easy and quick recharging by clipping onto the proprietary battery charger.
Touch-screen interface
The system can be managed either from the workstation or from the mobile receiving unit, which is equipped with a high-resolution touch-screen display and an intuitive graphical interface.
Signal Range
Up to 50 metres for the transmission between the probes and the mobile receiving unit; up to 350 metres for the data transfer between the mobile unit and the workstation.
Interoperability
Designed to interoperate with movement analysis, posturometry and stabilometry systems, thanks to the software integration through SDK or by means of the analogical output receiver.
It is intended also to interoperate with isokinetic machines (BIODEX, CYBEX and CON-TREX), rehabilitative robots (Reo-go, BTS ANYMOV) and virtual reality therapeutic systems (BTS NIRVANA) for the evaluation of real muscle activity during rehabilitation or sport training and planned testing activities.
