Brief Summary

This study aimed to (i) assess the reliability of myotonometer measurements in determining the mechanical properties of thenar muscle in healthy individuals and explore gender-based variations in these properties; (ii) examine the relationship between pinch grip strength and these mechanical properties.

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.

• 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.

• 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.
