Your Digital Dynamometer for Precise Strength Measurement

The ActivForce 2 is a highly precise, patented measurement device that combines two key functions in one. It serves as a digital dynamometer for strength testing and as an inclinometer for analyzing range of motion (ROM).

The device measures the force applied by you or your therapist and transmits the data in real time via Bluetooth to an intuitive app on your smartphone or tablet. This replaces subjective assessments with solid, comparable data. Therapists report from everyday practice that this level of objective measurement is a decisive factor in therapeutic success.

The Technology Behind It

Inside the robust, ergonomically designed housing is highly sensitive sensor technology capable of accurately measuring forces of up to 90 kg (200 lbs). The device connects to the app via the Bluetooth 4.1 standard, ensuring a stable connection and an exceptionally long battery life of up to one year under normal use. The ActivForce 2 is CE-certified as a Class I medical device, meeting high quality and safety standards.

How to Use it Correctly

The ActivForce 2 is designed to be deliberately simple to use, so you can focus on what really matters. With the included attachments and fastening strap, you can test virtually any muscle group or joint.

First, download the free ActivForce 2 app and pair the device with your smartphone or tablet via Bluetooth. In the app, select the appropriate test, either for a specific muscle group (e.g. knee extensors) or for a range of motion measurement (e.g. knee flexion). Next, position the device as shown in the in-app instructions and, if needed, use the padded attachments for added comfort. To perform the measurement, press against the device with maximum force for a few seconds, or move the joint to the end of its available range of motion. The result is displayed immediately in the app, automatically saved, and can be directly compared with previous measurements or the opposite side.

The key to success lies in regular use. Always perform measurements under the same conditions to ensure high comparability. The data collected with the ActivForce 2 provides an invaluable foundation for intelligent, safe, and effective training, as well as optimized rehabilitation.

Different User Groups for the Digital Dynamometer

The ActivForce 2 is a versatile tool designed for a wide range of users. It’s equally at home in professional diagnostics and in motivated home training.

For Rehabilitation Patients

After surgery (e.g. ACL reconstruction) or a sports injury, targeted and symmetrical strength rebuilding is crucial. With the ActivForce 2, you can objectively assess whether your injured leg has regained the same strength as the healthy side. This gives both you and your therapist confidence and provides clear, tangible benchmarks on the path back to full load-bearing capacity.

For Ambitious Athletes

You want to improve performance and prevent injuries? Muscular imbalances are a common underlying cause. With the ActivForce 2, you can identify whether your left and right sides are equally strong, revealing exactly where weaknesses still exist and where targeted work is needed.

For Therapists and Trainers

Offer real added value through data-driven support. Document baseline strength, track therapy progress objectively, and adjust training plans based on precise measurement data. Exportable reports provide an ideal foundation for communication with physicians and insurance providers.
