The measurement process consists of the following steps
- Prepare and Upload the Measurement set from Myoton Desktop Software.
- Press the ON/NEXT button or tap “Measurements” on the main screen.
- Press the ON/NEXT button to select the first Subject in the list or tap the one below.
- Press the ON/NEXT button to select the first Pattern in the list or tap the one below.
- Press the ON/NEXT button to “Perform new measurement” or tap the one to view the results of previous measurements.
- Place the Probe perpendicular to the intact skin surface directly on the pre-marked measurement point above the Object (e.g. muscle or tendon) being measured.
- Move the Device towards the skin until the green light is illuminated to indicate the range of measurement position.
- Hold the Device gently and keep it steady within the range of the measurement position until the Device automatically performs the measurements.
- Press the ON/NEXT button or tap “Finish” when all measurements have been completed.
- Download the results to the Myoton Desktop Software for import and further analysis.
Given the measurement method is relatively new for research and medical community, the production of reference values for various skeletal muscles, throughout the gender, age groups, life styles, occupations, sports, races and medical conditions, is a challenging task that can be accomplished with the dedicated international co-operation of researchers. However, based on the existing literature and observations, most of the adult’s superficial skeletal muscles that are measured in the relaxed state, irrespective of its physical condition, normally fall into the following ranges:
- F – 12.0 to 18.0 [Hz]
- S – 220 to 380 [N/m]
- D – 1.00 to 1.60
- R – 14.0 to 30.0 [ms]
- C – 1.00 to 2.00
- Systematic exercise or natural muscle development leads to the increase of muscle stiffness.
- Muscle stiffness of an adult person can change as much as 45% as the result of systematic sports exercise over the years (in absolute values for e.g. from 240 to 360N/m).
- Systematic exercise of fast and powerful repetitive muscle contractions (e.g. sprint) develops higher elasticity i.e. lower decrement of involved key muscles.
- For instance, children’s (age from 5 to 10 years) muscles, when compared to adult’s muscles, tend to present significantly higher elasticity (Decrement 0.7 versus 1.2 and higher), but lower stiffness (below 200N/m versus above 250N/m).
