Outcome Measures

Primary Outcomes (3)

• Delta (Y)AP sway /mm

  The anteroposterior COP sway length is the total distance traveled by COP in AP axis during the test time . The smaller the delta (y) , the better is the postural stability. It is an effective evaluation index in numerous populations and balance condition.

  Through study completion an average of 5 months

• Delta (X)ML sway /mm

  Mediolateral COP sway is the total distance traveled by COP in ML axis during the test time . The smaller the delta (x) , the better is the postural stability. It is an effective evaluation index in numerous populations and balance conditions.

  Through study completion an average of 5 months

• Average COP speed /mm.s

  is calculated by dividing the COP path length by testing time. In addition to the total COP average velocity, the average COP velocity components in the AP and ML directions can also be calculated. COP speed is an indicator of the efficiency of the postural control system. The average COP speed value is small, which is considered a good performance of posture control

  Through study completion an average of 5 months

Underweight group (A):

This group will be underweight group according to BMI- for age percentile growth chart ranged from BMI-for-age \< 5th percentiles.

Normal weight group (B):

This group will be with normal weight according to BMI- for age percentile growth chart which ranged from BMI-for-age 5th to 85th percentiles

Overweight group (C):

This group will be an overweight group according to BMI- for age percentile growth chart which ranged from BMI-for-age 85th to 95th percentiles

Obese group (D):

This group will be obese group according to BMI- for age percentile growth chart which ranged from BMI-for-age \> 95th percentiles and \<99th percentile

Eligibility Criteria

• Age: 16 Years - 18 Years
• Sex: all
• Age Groups: Child (0-17), Adult (18-64)
• Sampling Method: Probability Sample

Study Population

They will be assigned into four group of equal numbers according to (BMI) body mass index for age percentile obese group (n=50), overweight group (n=50), underweight group (n=50) and normal group weight (n=50). They will be assigned as following: Normal weight group (B): This group will be with normal weight according to BMI- for age percentile growth chart which ranged from BMI-for-age 5th to 85th percentiles Overweight group (C): This group will be an overweight group according to BMI- for age percentile growth chart which ranged from BMI-for-age 85th to 95th percentiles Obese group (D): This group will be obese group according to BMI- for age percentile growth chart which ranged from BMI-for-age \> 95th percentiles and \<99th percentile
