Brief Summary   In this study it will be recruited participants with and without neck pain, then pain ratings will be taken and screen time questionnaire will be taken from all participants. Then neck muscle endurance tests will be taken to each participant so that it can be compare the relation between screen time affects the neck muscle endurance in those who have neck pain and non neck pain. Then all the data will be recorded and fill in the excel sheet. And using statistical appropriate tools result will be calculated.
