Time Need to Detect Mobile Phone Use to Prevent Muscle Fatigue

Relation Between Muscle Fatigue And Time Use Of Smartphone In School Age Children

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.

Study Overview

• Status: Unknown
• Conditions: Mobile Phone Use
• Intervention / Treatment: Device: mobile phone

Detailed Description

-Purpose of the study:

To investigate the electrical muscle activity during used mobile phone

-Back ground :

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.

-Hypotheses:

There are no statistical significant relation between time of used smart phone and muscle fatigue.

-Subjects:

One hundred fifty healthy children of both genders will participate in this study.

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)
