MyotonPRO User Manual 1.3.3 Areas of application MyotonPRO can be applied, for both clinical and non-clinical purposes, to assess superficial skeletal Muscles or other soft biological tissues. Examples of possible applications of the Device are: 1. in clinical medicine: monitoring the changes caused by Muscle disorders, obtaining supplementary information when diagnosing Muscle diseases, evaluation of the benefits of applied interventions, evaluation of the benefits of rehabilitative treatments; 2.
MyotonPRO User Manual A diagram of the measuring process: The measuring process of the Muscle consists of the following: 1. Constant pre-pressure4 is applied to the skin surface above the Muscle being measured, thereby slightly compressing the subcutaneous superficial tissues. 2. On the Muscle located under the subcutaneous compressed tissues, a light, quick-released mechanical impulse is exerted by the Device at constant mechanical force. 3.
MyotonPRO User Manual c) in general, the accumulation and recuperation of mechanical energy in the Muscles and Tissues is higher than subcutaneous superficial tissues. 1.3.5 Limitations The Device cannot measure: Muscle groups; Thin Muscles (< 3mm); Muscles with small mass (< 20 g); Un-palpable Muscles; Deep Muscles located under layers of other Muscles; Tissues that are not categorised as soft biological tissue.
MyotonPRO User Manual Important information 2.1 Safety and precautionary measures Do not attempt to disassemble the Device! Any unauthorized disassembly of the Device will void the Warranty and Service! Please disconnect the Device from the adapter and mains power supply before use. The Device is not waterproof. Do not use water or chemicals for cleaning. Never immerse the Device in any liquid. For external cleaning, you may use non-woven pads saturated with 70% Isopropyl Alcohol.
MyotonPRO User Manual 2.2 Requirements for the measuring process This chapter focuses on the information related to and procedures involved in achieving highly reliable measurement results for Muscles and other soft biological tissues. Please read the following instructions very carefully! 2.2.1 Range of measuring angles Measuring under different angles the following principles must be followed: Description Picture 1.
MyotonPRO User Manual 2. It is recommended6 no to exceed measurement angles over 100⁰ from vertical position as shown on the figure. In the picture: A - The Device side view B - The cross-section of the Object being measured GV - Gravity vector 3. In case of conducting measurements with the Device positioned horizontally, the Device must be in flat position, the screen is either facing directly up or down. Tolerance of flat position is +/- 10⁰.
MyotonPRO User Manual 2.2.2 Requirements for the measuring environment The measuring environment must enable the measurement procedure to be conducted without any disturbing external factors (e.g. bright light, disturbing sound, vibration, overly high or low temperature, disturbance from third parties, etc.). 2.2.3 Subject preparation When preparing the Subject to be measured, the Operator should: 1.
MyotonPRO User Manual 3. perform the following actions: 10 establish the location and contours of the Muscle to be measured and mark by the Medical Skin Marker (see chapter 1.
MyotonPRO User Manual 7. the hand holding the Device is supported in such a way that guarantees the Device’s maximum stability and a comfortable measuring position for the Operator throughout the series of measurements; 8. during the measurement series, the Device is held gently without gripping it tightly12; 9. during the measurement series, the Operator’s attention is focused on the Probe and maintenance of the Device’s measuring position, and no other actions interfere with this (e.g., talking).
MyotonPRO User Manual 2.3 Interferences of Co-oscillation Every measurement includes automatic interference detection14 to verify if the oscillation of the tissue being measured was: 1. sufficient for the computing of parameters (see chapter 2.3.1); 2. generated without the Plastic Deformation (see chapter 2.3.2); 3. registered without the Probe Jump Off (see chapter 2.3.3); 4. registered without Excessive Noise (see chapter 2.3.
MyotonPRO User Manual The acceleration curve with at least three positive peaks is characteristic of adequate natural oscillation of the measured tissue (see Figure 1). If the tissue oscillation was not sufficient, the time of mechanical impulse should be changed (Tap time) depending on the properties of the measured tissue.
MyotonPRO User Manual mechanical impulse time (Tap time) can be decreased and/or the surface area of the Probe can be changed either by using bigger diameter probe (5 to 10mm) or by the attachment of a cap. Both of these options can be ordered separately from the manufacturer. 2.3.3 Probe jumps off skin surface If the Probe jumps off the surface of the skin during measurement, the raw signal17 of the acceleration curve is as shown in Figure 3 below.
MyotonPRO User Manual 2.3.4 Excessive noise The acceleration signal may have excessive noise which produces incorrect measurement results and potentially large variations in the measurement series. Excessive noise may occur for the following reasons: a) The Probe is in contact with the Device probe opening during the measurement (see Figure 4), b) A damaged19 or faulty Device.

MyotonPRO User Manual Appendixes Appendix 1 – Definitions of parameters STATE OF TENSION F – Oscillation Frequency [Hz] indicates the Tone (that is, intrinsic tension) of a muscle in its passive or resting state without any voluntary contraction (EMG base level). Hypertonia and respectively increased intramuscular pressure causes reduced blood supply, which brings on worse muscle recovery and quicker muscle fatigue. Oscillation Frequency in contracted state indicates the tension of a muscle.
MyotonPRO User Manual VISCO-ELASTIC PROPERTIES R – Mechanical Stress Relaxation Time [ms] is the time for a muscle to restore its shape from deformation after a voluntary contraction or an external force is removed. Figure 5 on Appendix 2, Mechanical Stress Relaxation Time is the time between maximum 1 R deformation t and zero deformation t . C – Creep is the gradual elongation of a muscle over time when placed under a constant tensile stress.
