Introduction: Approximately 70% of the total population experience neck pain more than once a lifetime. The greater the amount of neck flexion that occurs during smart phone usage, the more stress is placed onto the spine, which causes neck pain. The Deep Neck Flexor (DNF) and the Deep Neck Extensors (DNE) muscles provide stability to the cervical spine during head and cervical spine movements. Deep Neck Flexor Endurance (DNFE) and Deep Neck Extensors Endurance (DNEE) are important component of cervical spine function. Aim of this study was to find out the effect of smart phone addiction on deep neck flexors and extensors endurance. Method: Neck Flexor Muscle Endurance Test (NFME test): The test was performed in supine and crook lying positions with the chin maximally tucked and maintained isometrically. The subject lifted the head and neck until the head was approximately 2.5 cm off the plinth while maintaining the chin retracted to the chest. Neck Extensor Muscle Endurance Test (NEME test): The subject was put in a prone position with the head protruding from the plinth and supported on a stool, arms at side. Then the subjects were asked to retract the chin and hold the head steady in a horizontal position while the stool was removed. Result: On analysis using Pearson Coefficient correlation between Mobile addiction and Neck Flexors endurance, r value was 0.1049 (p=0.3673) was not significant. On analysis using Pearson Coefficient correlation between Mobile addiction and Neck extensors endurance, r value was -0.1251(p=0.2816) was not significant. Conclusion: We conclude that there is no direct relationship between mobile addiction and neck flexors endurance. Also, it is concluded from above study that there is no direct relationship between mobile addiction and neck extensors endurance.
