Completed
Conditions
Smartphone Addiction
Interventions
Other: Evaluating wrist flexor and extensor peak torque
Other: Evaluating functional disability
Other: Evaluating hand grip strength
Registration Number
NCT06497257
Lead Sponsor
Cairo University
Brief Summary

The present study aimed to measure wrist flexor and extensor muscle strength, hand grip strength, wrist pain and function in smartphone addicts and non-addicts

Detailed Description

Smartphones have become ubiquitous worldwide, offering significant potential for medical applications by providing healthcare professionals and students with instant access to resources for informed decision-making. However, despite their benefits, overuse of smartphones can lead to physical health issues. Grip strength is recognized as an indicator of overall muscle strength, upper limb function, and various health conditions. Isokinetic testing, a reliable method for measuring muscle performance, has been widely used in studying low back pain but less commonly applied to wrist strength assessment.

Currently, there is a lack of evidence regarding the impact of smartphone overuse on wrist flexor and extensor peak torque, handgrip strength, and function. This research aims to investigate these aspects, providing insights into upper extremity function and potentially aiding ergonomists in addressing musculoskeletal disorders. The study's findings could contribute to the biomechanical evaluation and design of upper extremity tasks, enhance understanding of wrist functioning, and inform ergonomic design considerations. Additionally, the results may help smartphone users adopt better postures and grasping techniques to minimize injuries and maintain hand function, ultimately improving their quality of life.
