Completed

• Conditions: Muscular Tone

• Registration Number: NCT06004635
• Lead Sponsor: Ilke KARA

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.

Detailed Description

Investigating the mechanical properties of hand muscles using simple applicable methods such as myotonometer can help to evaluate the effectiveness of programs used in hand rehabilitation, optimize the skills of performance-oriented individuals such as athletes and musicians, and create individualized treatment and training programs. In musculoskeletal-related pathologies such as carpal tunnel syndrome, studying the mechanical properties of the thenar muscles may be important to better understand hand grip strength, hand function and mobility. However, the use of myotonometer in the evaluation of the mechanical properties of the thenar muscles requires a reliability study. Accordingly, the aims of our study are: 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.

Primary Outcome Measures

Name	Time	Method
Stiffness (N/m)	30 Minutes	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.
Muscle tone (Hz)	30 Minutes	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.
Elasticity (Logarithmic decrement)	30 Minutes	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.
