BTS PocketEMG

The BTS PocketEMG is an innovative device designed for physicians, trainers, therapists and researchers who require a lightweight powerful EMG system with unparalleled signal quality.
The BTS PocketEMG measures muscle activity using surface electrodes. The data allows for the analysis of muscle activation, duration, intensity and muscle fatigue.

The device interacts wirelessly with your laptop or desktop and uses our proprietary Myolab software package for signal visualization, processing and reporting. The device is small enough for the patient to wear comfortably on their waist un-tethered to the computer. It has 16 EMG channels with individual frequency sampling rates up to 10 KHz. The device is capable of storing up to 8 hours (max. battery life) of signal processing internally, for acquisitions away from the lab.

The PocketEMG is typically used for evaluations in

Ergonomics
Gait analysis
Physical Therapy, Orthopedics and Rehabilitation
Biomechanics and Kinesiology
Sport, Human Performance and Exercise Science

The PocketEMG comes with Myolab or Myolab Clinic, two powerful BTS software applications for displaying, processing and reporting EMG signals.

Myolab Clinic includes a protocol for the functional evaluation of walking and uses foot switches to automatically identify stride phases.

Together with Myolab Clinic, the BTS PocketEMG becomes the perfect device for clinical applications such as gait analysis, the evaluation of neurologic and orthopaedic pathologies, pharmacologic therapies, evolution of motor deficiencies, use of orthesis and rehabilitative follow-ups.

Main features:

Compact and lightweight
Because of its weight of less than 300 grams and very small size, it is perfectly suited for use on children.

Powerful and complete
16 EMG channels and 8 additional analog foot switches, adjustable based on the weight of the patient.
6 additional digital channels.
Software oscilloscope to set up gains and crosscheck.

Easy to use
Setup controlled by the patient unit or by the remote station
Intuitive graphical interface
Large interactive display

Advanced technology
10 kHz sampling frequency
16 bit resolution
Wireless data transmission with Wi-Fi protocol
Local backup of data: if the link is interrupted all data can be quickly restored.

LAB and Holter functions
The absence of connecting cables, the on-board logic and the data saved on interchangeable cards allow extended monitoring, following the patient in his or her daily activity.

Expandable
Up to 8 GB Secure Digital memory cards.

Fully integrated with BTS motion capture system and others
Designed to operate with systems for movement analysis, posturometry and stabilometry.
