Real-Time EMG Biofeedback

The Noraxon EMG Biofeedback App provides users with a portable, easy-to-use platform to visualize muscle activity and deliver real-time feedback during rehabilitation, training, or performance sessions. Now available on iOS and Android, the app seamlessly connects to Ultium or Core EMG sensors via Bluetooth, enabling quick setup and instant data visualization. With its redesigned interface and intuitive workflow, users can capture and document EMG sessions, monitor progress, and generate reports—anytime, anywhere.

Key Capabilities: 

  • Multiple Live Visualization Modes
    Line, bar, circle, and camera-assisted views allow feedback to be tailored to each application, improving understanding and engagement during training.

  • Session-Specific MVC Calibration
    MVC values are captured and applied at the session level to improve the accuracy and relevance of EMG normalization while accounting for day-to-day variability.

  • Integrated Patient & Session Management
    Patient profiles, session histories, and metadata are managed directly within the app to keep evaluation, training, and documentation integrated.

  • Threshold-Based Feedback with Audio Cues
    Custom activation thresholds provide real-time visual and audio feedback when targets are met, reinforcing correct activation during tasks.

  • Comprehensive, Customizable PDF Reports
    Automatically generated PDF reports include key EMG metrics and symmetry data, with fully customizable sections for documentation and sharing.

  • Cross-Platform Availability (iOS & Android)
    Available on iOS and Android, the Biofeedback App runs on tablets and smartphones already in use, supporting flexible and consistent workflows.

Using EMG Biofeedback

EMG biofeedback provides real-time feedback on muscle activation during movement and exercise, helping users better understand when and how muscles are activating. By turning muscle activation into clear visual or audio feedback, EMG biofeedback can support improved awareness, learning, and engagement during rehabilitation. The Noraxon EMG Biofeedback App applies these principles through an easy-to-use interface with configurable feedback and simple progress tracking.

Benefits of EMG Biofeedback:

•  Improves muscle awareness
•  Reinforces consistent activation
•  Supports motor learning
•  Increases patient engagement
•  Enables objective progress tracking

Real-Time EMG Biofeedback
Up to 4 channels

Live EMG signals are processed and displayed in µV or %MVC, enabling immediate interpretation of multi-muscle activation without post-processing.

Template Training
2 Channels: 1 Template, 1 Training

A reference muscle activation pattern is recorded and displayed as a visual overlay to guide symmetry during training.

Structured Work/Rest Training
2 Channels

Configurable work and rest intervals structure repetitive training while automatically tracking repetitions and performance.
