The Reliability of Myotonometer in Evaluating the Muscle Tone and Biomechanical Properties of the Forearm Muscles

The Reliability of Myotonometer in Evaluating the Muscle Tone and Biomechanical Properties of the Forearm Muscles: Investigation of the Effect of Grip Strength on Mechanical Features

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.

Inclusion Criteria:

• Age≥18 years
• Body mass index < 30 kg/meter square
• Having no upper extremity injuries
• Willing and able to provide the written informed consent for the study

Exclusion Criteria:

• Use of medication that will affect muscle tone
• History of lateral or medial epicondylitis, trauma (elbow, hand or wrist), cervical radiculopathy, peripheral neuropathy or nerve injury (axillary, median, ulnar, radial, musculocutaneous), systemical diseases, muscle disorders (e.g. genetic diseases, neuromuscular disorders)
