Correlation Between Body Mass Index, Manual Dexterity and Handgrip Strength in School Aged Children

Study Overview
=================
Brief Summary
-----------------
The purpose of current study is to investigate the relation between body mass index, manual dexterity and handgrip strength in school aged children having normal weight, overweight and obesity.

Detailed Description
-----------------
The study targeted the normal weight, overweight and obese students (9-11) from both sexes will be selected from governmental primary schools. Study design: Cross sectional observational correlational study. A. Inclusion criteria: The students' age ranges from 9 to 11 years. Normal weight, Overweight and obese students were included both boys and girl will be included. B. Exclusion criteria: The students will be excluded from the study if they have one of the following: Congenital abnormalities or medical conditions, which may affect the study. Musculoskeletal problems such as previous or recent orthopedic surgery, fractures, prostheses, inflammation of the fingers, arms, or shoulder. Visual or hearing defects. Motor, behavioral, or neurologic disorders and learning disabilities. All children will be assessed using: the Standard weight and height measuring scale to determine their BMI. Assessment of manual dexterity will be carried out by using the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition (BOT-2) (Bruininks and Bruininks, 2005). Handgrip strength will be assessed by hand dynamometer.
