Brief Summary

The primary aim of this study was to evaluate the intra-rater and inter-rater reliability of MyotonPRO in measuring muscle tone and mechanical properties of the wrist extensor and flexor muscles in healthy young adults. The secondary aim is to examine whether grip strength has any effect on muscle tone and biomechanical properties.

Conditions

Muscular Tone; Viscoelasticity

Keywords

elasticity; hardness; forearm muscles

Outcome Measures

Primary Outcomes (3)

• Muscle tone (Hz)

  The muscle tone which is a biomechanical property of the forearm muscles will be evaluated with a portable hand-held myotonometer. This myotonometer (MyotonPRO - Tallinn, Estonia) is non-invasive and provides a quantitative assessment of a muscle's biomechanical properties. The MyotonPRO applies a short-intensity mechanical impulse on the skin overlying the muscle or facia. The tissue's response then generates a signal that is recorded, and an internal software program produces an acceleration graph. To determine the feasibility of the MyotonPRO for assessing the muscle tone of forearm muscles measurements will be performed and recorded.

  Day 1

• Stiffness (N/m)

  The stiffness which is a biomechanical property of the forearm muscles will be evaluated with a portable hand-held myotonometer. This myotonometer (MyotonPRO - Tallinn, Estonia) is non-invasive and provides a quantitative assessment of a muscle's biomechanical properties. The MyotonPRO applies a short-intensity mechanical impulse on the skin overlying the muscle or facia. The tissue's response then generates a signal that is recorded, and an internal software program produces an acceleration graph. To determine the feasibility of the MyotonPRO for assessing the stiffness of forearm muscles measurements will be performed and recorded.

  Day 1

• Elasticity (Logarithmic decrement)

  The elasticity which is a viscoelastic property of the forearm muscles will be evaluated with a portable hand-held myotonometer. This myotonometer (MyotonPRO - Tallinn, Estonia) is non-invasive and provides a quantitative assessment of a muscle's viscoelastic properties. The MyotonPRO applies a short-intensity mechanical impulse on the skin overlying the muscle or facia. The tissue's response then generates a signal that is recorded, and an internal software program produces an acceleration graph. To determine the feasibility of the MyotonPRO for assessing the stiffness of forearm muscles measurements will be performed and recorded.
