Product Information
What is MyotonPRO?
MyotonPRO is a patented handheld device that measures biomechanical and viscoelastic properties of non-invasive soft tissues such as muscles, tendons, ligaments, and skin. The device is rectangular, smartphone-sized, and user-friendly, primarily designed for research use.
Target Users and Applications
Suitable for researchers, physiotherapists, medical professionals, sports physiologists, and lab studies (e.g., neurorehabilitation, athlete recovery). The technology is also applicable in specialized medical fields (e.g., Parkinson’s, stroke) and high-tech applications such as space medicine or sports biomedicine monitoring.
Technology Used (“Tap-and-Listen”)
The device uses Mechanical Dynamic Response (MDR): it delivers a very soft mechanical impulse (“tap”) to the tissue and records the resulting oscillations. These are automatically converted into biomechanical parameters.
Measured parameters:
- F (Frequency): natural oscillation frequency, i.e., muscle tone
- S (Stiffness): dynamic stiffness
- D (Decrement): elasticity, logarithmic damping
- R (Relaxation time): stress relaxation time
- C (Creep): deformation over time under constant load
How the Technology Works in Practice
The device is placed on the skin surface; a rapid impulse is applied, followed by recording of tissue oscillations and automatic calculation of parameters. This allows detection of small changes in muscle tone, stiffness, or elasticity, which can be used to:
- Assess training and rehabilitation effectiveness
- Detect overuse or fatigue
- Perform comparative analyses in sports or rehabilitation scenarios
Issues MyotonPRO Addresses
- Objective assessment: replaces subjective palpation with precise measurements
- Speed and usability: portable, fast, and user-friendly
- Reliable for research and clinical applications: many studies show high intra- and inter-rater reliability for stiffness and elasticity
Recommended Usage
Although the manufacturer website does not provide detailed instructions, studies describe:
- Marking the measurement point, placing the device on the skin, and applying the impulse multiple times (e.g., 3–5) for stability
- For best reproducibility, measurements can be taken by the same or different operators
What’s Included
Typically, the kit includes:
- Handheld device (~230 g, 162×67×28 mm)
- Battery system (charging time up to 5 hours)
- Software/interface for result analysis
- Likely includes manual and charger
Evidence-Based Validation
- Medicina (2024): systematic review of 48 studies across 31 muscles; high intra- and inter-rater reliability for parameters like frequency and stiffness
- Scientific Reports (2021): upper limb measurements in chronic stroke patients – ICC 0.72–0.97, very high reliability
- Frontiers in Sports and Active Living (2024): high reliability in various athlete groups, ICC >0.74; measured stiffness, tone, elasticity
- Frontiers in Sports Science (2022): wrist validation study – measures elasticity and stiffness accurately compared to tribometers; portable and practical

The MyotonPRO device is a patented technology designed for the advanced assessment of mechanical properties. Myoton introduces sports science to muscle evaluation, enabling non-invasive, cost-effective, quick, and easy measurements of superficial skeletal muscles and tendons.
Muscle Tone
Oscillation Frequency (Hz) is the mechanical tension in a relaxed muscle which characterises the Tone (intrinsic tension on the cellular level). It describes the restoration conditions of the muscle between efforts. A tone higher than normal disturbs the muscle's blood supply conditions, as the blood vessels of the muscle are more contracted and less blood reaches the muscle. Increased tone is relatable to pain, atlethic underachievement, overload, muscle fatigue and poor recovery. Low tone may indicate weak muscles.
Muscle Stiffness
Dynamic Stiffness (N/m) is a muscle's ability to resist a force deforming the muscle. In terms of athletic performance, it is related to the resistance of the antagonist muscles during movement. Stiffer muscles require greater effort to stretch the antagonist muscle; this leads to worse economy of movement. Asymmetry of stiffness between body sides can disturb the rhythm of the movements.
Muscle Elasticity
Is a muscle's ability to restore its initial shape. It describes the condition of the muscle's blood supply during the effort and the ability to increase the speed of the movement. The blood supply of a skeletal muscle during effort can only be effective if the muscle restores its shape relatively quickly during the interval between two contractions. In other words - the muscle must have good elasticity (a muscle’s elasticity is by definition the ability to restore its shape). Decreased elasticity brings on quicker muscle fatigue and the speed of a movement is limited if the muscle is less elastic.
