MyotonPRO is a digital palpation device for measuring muscle health and physical condition. The device was developed as a research device to investigate the possibilities of measuring muscle parameters non-invasively.
The device has a mechanical actuator, that sends a tap pulse to the muscle and records the acceleration response. Later, digital filtering and processing is used to process the data and calculate numberic parameters.

Measured parameters

F Natural Oscillation Frequency [Hz], characterizing Tone or Tension
S Dynamic Stiffness [N/m]
D Logarithmic Decrement of natural oscillation, characterizing Elasticity
R Mechanical Stress Relaxation Time [ms]
C Ratio of deformation and Relaxation time, characterising Creep (Deborah number)
