Correlation Between Body Weight and Foot Progression Angle in Adolescents

Study Overview
=================
Brief Summary
-----------------
Obesity is associated with functional decline , altered spatiotemporal gait parameters (e.g. lower gait speed, shorter strides, and increased step width), and a significantly higher metabolic cost of walking compared to people with normal body weight. Obesity also negatively affects balance control.This study will investigate foot progression angle in adolescents related to their weight and category classification based on the CDC (Centers for Disease Control and Prevention) growth charts.

Eligibility Criteria
-----------------
Inclusion Criteria: All children have normal stature for age percentile according to CDC chart. The sample will include both sex and will be divided in to 4 groups according to the CDC (Centers for Disease Control and Prevention) growth charts. All children are normal &perform all activities of daily living They were able to understand and follow verbal commands and instructions included in the testing procedures. Exclusion criteria: All of them could be part of recreational activities in their public schools but no competitive sports. Children who participated in any regular sport activities involving the lower extremities will be excluded. None of them had any surgical intervention in the lower extremities. None of them had any history of musculoskeletal deformities or neuromuscular disorders. They had neither visual, auditory defect.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| foot progression angle for healthy group | participants in healthy group will be assessed for foot progression angle (FPA). The FPA is defined as the angle made by the long axis of the foot from the heel to 2nd metatarsal and the line of progression of gait | assessed immediately after the procedure | 
| foot progression angle for overweight group | participants in overweight group will be assessed for foot progression angle (FPA). The FPA is defined as the angle made by the long axis of the foot from the heel to 2nd metatarsal and the line of progression of gait. | assessed immediately after the procedure | 
| foot progression angle for obese group | participants in obese group will be assessed for foot progression angle (FPA). The FPA is defined as the angle made by the long axis of the foot from the heel to 2nd metatarsal and the line of progression of gait. | assessed immediately after the procedure | 
| foot progression angle for underweight group | participants in underweight group will be assessed for foot progression angle (FPA). The FPA is defined as the angle made by the long axis of the foot from the heel to 2nd metatarsal and the line of progression of gait. | assessed immediately after the procedure |
