Immediate Effect of Post Deep Neck Flexors Endurance Test on Neck Reposition Accuracy in Smartphone Addictors

Neck reposition accuracy is the ability of the person to return to the specific starting point after a particular neck movement. Neck reposition accuracy error is a common issue in modern society but the sources of its development can be divers.

According to many researchers, along lasting neck reposition related errors disorganise different nerve conduction leading to muscle tone abnormalities around the neck and occiput, hence affecting the proprioceptive sensibility in the neck and cervical spine at large as well as eliciting associated musculoskeletal complaints.

The purpose of this study was to evaluate the immediate effect of Deep Neck Flexors endurance test on neck reposition accuracy.

A total of 30subjects, age group 18–30 years and smart phone users at SRM Institute of science and technology, SRM College of physiotherapy, Katankulathur.

Smart phone addiction scale (SAS) was used to assess the smartphone usage level, along with isometric neck endurance test, to assess immediate effects on the repositioning of the neck accuracy. Additionally a special gyro motion sensor device was used to assess the accuracy of neck repositioning before and after exercise/Test.

SAS (Smartphone addiction scale) and gyroscope special device.

Results showed a significant difference in head reposition errors after performing the endurance test with a P value less than.001 (p<.001) and a negative correlation between holding time during the test (Deep Neck flexors endurance test)
