简要总结
To compare between two different positions (forward head position and neutral position) when using mobile phone by hand using nerve conduction velocity and F-wave of upper limb nerves ( ulnar, median and radial) in 4 different times.
详细描述
PURPOSE:
- 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.
