About this study
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
Read the 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.

The record says: finished, as of the sponsor's last update on 27 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Measurement of wrist flexor peak torque (time frame: 1 month). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Aug 2024.
