Brief summary
The aim of this study was to investigate the tonus, stiffness and elasticity of the hand and wrist muscles in intensive smartphone use.
Detailed description
Consent was obtained from the students with the 'Informed Voluntary Consent Form' and the sociodemographic data of the students were recorded on the previously prepared Descriptive Data Form. The students were asked to fill out the Smartphone Addiction Scale-Short Form. Before starting the clinical evaluation, anamnesis was taken from the students and their general health status, phone usage time (minutes) and exclusion criteria were questioned. Myotone evaluations of the tenar region, flexor carpi radialis, flexor carpi ulnaris, extensor digitorum, extensor carpi radialis and extensor carpi ulnaris muscles were performed. Then, the standard grip strength of the dominant and non-dominant side hand was evaluated with Saehan hand dynamometer and the lateral grip strength of the thumb was evaluated with Saehan pinchmeter.
Interventions
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.
OTHERHand 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.
OTHERFinger 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.
OTHERMyoton 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.
