A Correlation Study on Smartphone Usage Duration with Hand Grip Strength in Young Adults

Shimaiyla Asif Khan | Rincy Sibi Joseph [2]


Abstract: Background: Smartphone are indispensable tool for people of all ages around the world today. In this context, smartphones have become an essential part of life, not only in matters related to communication, but also as essential social accessories. Frequent smartphone use without taking regular rest period may result in cumulative trauma disorders to the neck, shoulder, hands and wrist. These disorders may occur because smartphone use requires thumb and finger interaction with the screen. Repetitive static motion of the hand may decrease blood supply of it and prevent nutrient's being delivered to muscle thus leading to pain & muscle fatigue. Thus, this study aimed to determine the correlation between smartphone usage duration and hand grip in Mumbai among young adults. Method: 123 young adults participated in the study. The procedure was explained in the language best understood by the participants. Smartphone usage duration was recorded using daily average screen time. Hand - grip strength measurement was assessed using a Hand - Held Dynamometer. Results: Average daily usage of smartphone (in hours) and hand grip strength (kg) among the participants was 5.6?1.6 and 23.7 ? 11.1 respectively. There was a weak but significant correlation between the variables i. e. the more the screen time weaker the hand grip strength. Conclusion: This study provides an insight into potential association between excessive device use and physical health. thus, we can conclude that increase in screen time has a negative effect on the hand grip strength.
