Effect of Texting and Writing on Grip and Pinch Strength

Study Overview
=================
Brief Summary
-----------------
Texting and writing are common hand activities among college students. Students tend to spend increasing hours of texting and writing for every day activities in addition to the academic assignments that are mainly on line and through distance education. The effect of such daily activities on hand grip and key pinch strength has not been studied among college students.

Detailed Description
-----------------
Students will be recruited from physical therapy department of college of medical rehabilitation sciences after satisfying the inclusion and exclusion criteria. Participants will be randomly assigned to one of the four groups (texting 10 minutes, texting 15 minutes, writing 10 minutes and writing 15 minutes). Participants will be blinded to the outcome measures and the evaluator will be blinded to the participants assigned group. Hand grip strength and key pinch strength will be the main outcome measures. Participants demographics will be gathered in addition to recreational status, risk factors, pain body diagram and number of hours spent for texting and writing in every day life.
