About this study
Official title: EFFECT OF DE QUERVAIN'S TENOSYNOVITIS ON HAND GRIP STRENGTH AND QUALITY OF LIFE IN SMART PHONE ADDICT ADOLESCENTS
The goal of this Cross Sectional Case Controlled study is to Investigate the effect of de quervain's tenosynovitis on hand grip strength and Quality of life among smartphone addicts' adolescents. The main question it aims to answer is:
Is de quervain's tenosynovitis influences hand grip strength and quality of life in smartphone addict adolescents?

Smart phone addicts' adolescents were equally distributed into two groups:
Group A: Smart phone addicts' adolescents with de quervains Group B: Smart phone addicts' adolescents without de quervains (as a reference group).
Smart phone addicts' adolescents in the two groups were assessed regarding the following:
- Qe quervain's tenosynovitis by The Finkelstein test.
- The hand grip strength by handgrip dynamometer.
- The effect on the quality of life by Pediatric Quality of Life Inventory (PedsQL Version 4.0).
Read the detailed description
The objective of this Cross Sectional Case Controlled study is to thoroughly examine the impact of de Quervain's tenosynovitis on hand grip strength and overall quality of life among adolescents identified as smartphone addicts. The central inquiry of this research is:
Does de Quervain's tenosynovitis affect hand grip strength and quality of life in adolescents who are smartphone addicts?
To address this question, the study categorizes smartphone addict adolescents into two distinct groups:
Group A: Adolescents with de Quervain's tenosynovitis Group B: Adolescents without de Quervain's tenosynovitis (serving as the reference group).
Participants from both groups will undergo assessments focusing on the following criteria:
- Diagnosis of de Quervain's tenosynovitis will be conducted using the Finkelstein test.
- Hand grip strength will be measured utilizing a handgrip dynamometer.
- The impact on quality of life will be evaluated through the Pediatric Quality of Life Inventory (PedsQL Version 4.0).
This structured approach aims to provide valuable insights into the relationship between de Quervain's tenosynovitis and its effects on physical and psychological well-being in a population increasingly reliant on smartphone usage.
