Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
* To compare between forward head position and hand use of mobile phone on conduction velocity of upper limb nerves
* To investigate the F responses of upper limbs nerves.
* To investigate the compound muscle action potential (CMAP) amplitudes of median nerves
BACKGROUND:
Forward head position may affect the cervical nerve root so it can also affect nerve conduction velocity due to continues stretch on nerves, also the over use of smart phone by hand may be affected the hand nerves, so this study determine which one of them has more influence than the other.
If the forward head position has the worst effect on the upper limb nerves investigators must avoid the incorrect position of the head to avoid stretch and compression of the nerves.
HYPOTHESES:
There are no statistical difference between forward head position and hand use of mobile phone on conduction velocity of the nerves of upper limb.
SUBJECTS:
Normal one hundred fifty non-athketic adolescents of both genders will participate in this study. Their age ranges from 14-18 years.
METHODS FOR ASSESSMENT
1. Electromyography (EMG) will be used to measure nerve conduction velocity, F-wave, motor action potential
2. Soft collar will used to fixed the craniovertebral angle during used mobile phone Universal goniometer
3. Goniometer pro iPhone application

Study Groups

forward head position
nerve conduction velocity and f-wave applied to median , ulnar and radial nerve before and after 10,20 and 30 minutes in forward head position while Children will sit on chair with their feet on the ground without any tension, the upper limbs are rested in a table then, the angle between the line passing horizontally from the spinous process of C7 and the line passing between the tragus and spinous process of C7 will be measured by goniometer and goniometer pro application to evaluate the craniovertebral angle recording, we will fix the craniovertebral angle between 40.7° and 43.2°(severe FHP )
