Evaluation of Text Neck Syndrome and Hand Grip Force in Smart Phone Addiction Among Students of Jazan University

Pain pressure threshold for upper fiber of trapezius muscle

时间窗: 3 minutes

Using Algometer to measure pain pressure for upper trapezius trigger point which lies in the more horizontal fibers of the upper trapezius on the back of the shoulder, about halfway between spine and the acromion on right and left side for 3 repetition for each

Hand Grip Force

时间窗: 15 minutes

For measuring the grip strength, the subjects will be asked to sit on a chair with their hip joint flexed at 90 degree, and shoulder joint in a neutral position. The elbow is fixed at 90 degree flexion, forearm in a neutral position, and wrist at 0 to 15 degree radial deviation.The test will be performed twice, and the higher value between the two measurements will be selected. The subjects are allowed a rest time of more than 5 minutes after the first measurement to avoid examiner bias and to decrease physical stress

Pain pressure threshold for sternocleidomastoid muscle

时间窗: 9 minutes

Using Algometer to measure pain pressure for sternocleidomastoid muscle on right and left side for 3 repetition for each. Measurement will includes three sites on each side: 1. upper part of the sternal division of the muscle near to its insertion into the mastoid process. 2. he mid-part of the sternal division of the muscle. 3. lower end of this division near to its attachment to the sternum.
