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 provide flexible real-time feedback for different training and rehabilitation tasks.

    • Session-Specific MVC Calibration
      MVC values are captured per session to improve EMG normalization and account for day-to-day variability.

    • Integrated Patient & Session Management
      Patient profiles, session histories, and metadata are organized directly within the app.

    • Threshold-Based Feedback with Audio Cues
      Custom activation thresholds trigger real-time visual and audio feedback when targets are reached.

    • Offline Session Capability
      Sessions can be recorded and reviewed without an internet connection, enabling reliable EMG biofeedback where connectivity may be limited.

    • Comprehensive, Customizable PDF Reports
      Automatically generate PDF reports with customizable sections for documentation and sharing.

    • Cross-Platform Availability (iOS & Android)
      Runs on iOS and Android tablets and smartphones for flexible mobile 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
