Background: Smartphone has been an essential part of everyone’s life. In young adults, due to their developing musculoskeletal structures and they are growing tendency to use smartphones, these exposures are causing repetitive strain injuries in their fingers and thumb. As a consequence of the injury to the musculotendinous tissues, there is disruption of the joint proprioceptors located at the soft tissues of a joint, thus may lead to reduced joint position sense. Method: 58 young adults within the age group 19–34 years were categorized into 2 groups, smartphone addicts and non–addicts using Smartphone addiction scale–short version. The proprioception of both the hands was assessed using pinch aperture proprioception. Conclusion: The result showed that the dominant hand of smartphone addicts showed the highest measure of degree of error (3.22±1.72), which may lead to impaired fine activities with the pinch grip.
