Introduction: This study investigated the interactive effects between the levels of smartphone use on hand-grip strength and functional hand performance in young people. High levels of smartphone use diminished hand-grip strengths as well as and hand function that results in a reduction of handgrip strength of dominant hands in smartphone users. To create a self-diagnostic scale that could tell the difference between smartphone addicts and non-addicts. The smartphone addiction scale short version (SAS-SV) was shown to be reliable and accurate. The qDASH (Questionnaire for Disorders of the Arm, Shoulder, and Hand) is an automatic management region-specific outcome device designed to assess upper-extremity impairment along with symptoms. The key component of the qDASH is an 11-item disability/symptom scale.
Method: The observational cross-sectional study will be including 70 participants aged between 16 to 29 years from Ravi Nair College of Physiotherapy, India for study as per exclusion and inclusion criteria. Intervention, the span of the duration of analysis of the study will be 6 months. The Hand Dynamometer will be used, SAS-SV and qDASH questionnaire will be used to evaluate the smartphone addiction and assess the upper extremity functional independency.
Discussion: The Study will evaluate the hand performance and strength of smartphone in healthy participants. There was a link between smartphone addiction and hand-grip strength and upper-limb disability. There is a dismissive impact on youthful participants during the overuse of smartphone on their hand functions.
