Brief Summary

Using a smart phone while adopting a poor posture can cause various physical problems. The neck and shoulders are particularly vulnerable to pain due to smart phone use, with the muscles showing a high level of muscle fatigue, resulting in exhaustion and pain, Therefore, determining the durable time to use the smart phone will protect us from abnormal posture and protect our muscle and ligaments. Furthermore avoid the incorrect position of use smartphone position.

Conditions

Mobile Phone Use

Outcome Measures

Primary Outcomes (1)

• Maximum voluntary contraction and Root main square

  Maximum voluntary contraction and Root main square by using electromyography (EMG) of the upper trapezius (UT), brachioradialis (BR), flexor carpi ulnaris (FCU), and abductor pollicis brevis (APB) during phone operation

  1 day

Interventions

mobile phone DEVICE

The root mean square (RMS) of the signal will be calculated by using electromyography, and were normalized to the EMG data maximum voluntary isometric contraction (MVIC)

Eligibility Criteria

• Age: 12 Years - 14 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17)
• Sampling Method: Probability Sample

Study Population

All subjects shouldn't use the phone for an hour before the measurement Each child setting in a chair with their feet on the floor and the elbow slight flexion, holding a smartphone in favorite position of used smart phone using EMG surface electrode to record the muscle activity of the upper trapezius (UT), brachioradialis (BR), flexor carpi ulnaris (FCU), and abductor pollicis brevis (APB) during phone operation EMG signals are detected and the motor unite potential are measured until detecting changes in motor action potential. The root mean square (RMS) of the signal will be calculated, and were normalized to the EMG data maximum voluntary isometric contraction (MVIC)
