Smartphone Strain: Investigating The Effects on Handgrip and Key Pinch Strength in Collegiate Individuals
Main Article Content
Abstract
Background And Purpose: Smartphones have become indispensable in modern society. Young children and college students have become ardent smart phone users as a result of their social involvement with communication technology. Frequent smartphone use causes repetitive stress injuries to the thumb and fingers. Hand is the only prehensile organ in humans. The relationship between smartphone usage with handgrip strength and key pinch strength in college students must therefore be evaluated.
Methodology: 100 number of students were selected for study through random sampling based on inclusion and exclusion criteria. The subject’s testing position was maintained according to the American Society of Hand Therapist (ASHT) for measuring hand grip strength using Jamar Dynamometer and key pinch strength using Pinch Gauge Dynamometer.
Result: Un- paired t test was used to compare both hands grip strength and key pinch strength with normative data. Paired t test was used to compare right hand grip strength and key pinch strength with left hand grip strength and key pinch strength. Level of significance selected is p≤0.05.
Conclusion: The study shows that there is a significant decrease in grip strength and key pinch strength of both hands but no difference is seen between right and left hand grip strength and key pinch strength
