  • Muscle Biomechanics
  • Smartphone Addisction

Smartphone Addiction Scale-Short Form

Smartphone Addiction Scale-Short Form: In our study, the Smartphone Addiction Scale-Short Form will be filled out in order to evaluate the intensity of smartphone use of students, and the daily duration of smartphone use will be recorded. The scale is a 6-point Likert-type scale consisting of 10 items used to measure the risk of smartphone addiction. Scores obtained from the scale vary between 10-60 and an increase in the score indicates an increased risk for smartphone addiction. The cut-off score of the scale was determined as 31 for men and 33 for women. In the Turkish validity and reliability study, Cronbach's alpha coefficient was found to be 0.86.

Hand Grip Strength Assessment

Hand grip strength was measured with 'Saehan Hydraulic Hand Dynamometer'. Participants were informed about the correct holding position and use of the instrument. In the measured arm, the position of 90̊ flexion from the elbow joint and completely adjacent to the body was used. The participant's hand was placed in the second grip position of the dynamometer and asked to make the strongest grip he/she could make, right and left measurements were taken.

OTHER

Finger Lateral Grip Strength Assessment

Finger lateral grip strength was measured with 'Saehan Hydraulic pinch gauge'. Participants were informed about the correct holding position and use of the instrument. While the participant was sitting on a chair with arms supported, the shoulder was adjacent to the trunk and neutral, the elbow joint was in 90 ̊ flexion, the forearm was neutral, the wrist was in 0-30 ̊ extension and 0-15 ̊ ulnar deviation. Right and left finger lateral grip measurements were taken.

OTHER

Myoton Assessment

Myoton PRO device was used to objectively evaluate the biomechanical properties of the hand and wrist muscles such as tone, stiffness and elasticity. Tenar region, flexor carpi radialis, flexor carpi ulnaris, extensor digitorum, extensor carpi radialis and extensor carpi ulnaris muscles were evaluated bilaterally. Three measurements were recorded at one second intervals and the mean value was used for analysis.
