How does EMG measure muscle activity?

EMG records electrical signals generated by the activation of muscle fibers. EMG sensors—also known as electrodes—are attached to the skin over the target muscle. These detect voltage fluctuations that occur during muscle contractions. The higher the activity, the stronger the measured signal. These signals are recorded in real time, processed, and translated into clear visual or numerical outputs. This allows for precise tracking of when and how strongly a muscle is working.

What data does the myoact system deliver and how is it analysed?

The recorded signals are transmitted via Bluetooth to the myoact app. Parameters such as resting tone, maximum voluntary activation (MVA), muscular balance between the right and left side, and activation patterns over time are automatically analysed, graphically processed, and documented in structured reports. The intuitive display of EMG results makes it easy for both professionals and patients to understand the data. This enables the identification of deficits, visualisation of progress, and targeted therapy planning.

Why myoact?

myoact combines advanced medical technology with user-friendly application. Our EMG platform provides physicians, physiotherapists, rehabilitation centers, and training facilities with a precise yet practical tool for analyzing and treating muscular imbalances. We deliver deep insights into muscle activity and neuromuscular control, enabling the development of individualized, evidence-based therapy and training plans. myoact not only equips professional sports medicine users with an accurate analysis and monitoring tool, but also supports patient compliance and self-motivation on their journey to recovery or toward achieving personal peak performance in sports.

What is the myoact Mapping? How does an EMG muscle analysis work?

The myoact Mapping is a standardised method for assessing muscle activity in defined regions of the body. It enables structured analysis of typical muscle groups in just 3 minutes – such as in the back, pelvis, or shoulder area. Sensors are applied according to a fixed protocol to then test how the muscles behave at rest, during voluntary activation, and under involuntary activation. The system automatically documents activity profiles and generates an individualized report. Based on this data, muscular imbalances, asymmetrical activation, or control deficits can be visualized – objectively, reproducibly, and clearly presented.

What are the steps in an EMG analysis?

  1. History & Goal Setting:
    Select relevant muscle groups and test tasks based on the clinical picture.
  2. Preparation:
    Clean the skin and apply EMG sensors to standardised locations.
  3. Test Execution:
    Perform targeted muscle contractions, movement, or holding tasks under EMG monitoring.
  4. Data Collection:
    Measure muscle activity in real time.
  5. Analysis & Interpretation:
    Automatic calculation of key parameters, visualisation, and interpretation.
  6. Feedback & Therapy planning:
    Discuss the results with the patient and define concrete training or therapy goals.

What is EMG biofeedback and how does it work?

EMG biofeedback makes muscle activity visible in real time. This enables patients to learn how to specifically activate, relax, or symmetrically engage certain muscles. Feedback is provided, for example, via a curve on the screen, a color scale, or an acoustic signal. Training is engaging and motivating, evidence-based, and especially effective in cases of control deficits, functional pain, or post-operative rehabilitation.
Additionally, the biofeedback mode can be used to test which exercises actually recruit the desired muscle, enabling evidence-based selection of exercises for individualised training plans.
Zusätzlich kann unter Anwendung des Biofeedback-Modus getestet werden, welche Übungen tatsächlich den gewünschten Muskel rekrutieren, um auf diese Weise evidenzbasierte Übungen für einen individuellen Trainingsplan auszuwählen.

What technical requirements are needed for use?

The myoact system does not require any structural modifications. A tablet and Wi-Fi are sufficient. The sensors are wireless, reusable, and disinfectable; the software runs on Android and iOS and is intuitively operated. The system is mobile – ideal for private practices, home visits, or clinical use. myoact also provides technical support, updates, and training for a smooth setup and continuous operation.
