Brief Summary

investigate the compatibility of school furniture design

Conditions

Outcome Measures

Primary Outcomes (5)

• weight

  measured in kilograms

  up to 24 weeks

• height

  measured in centimetres

  up to 24 weeks

• Body mass index (BMI)

  It was calculated as the ratio of the subject's height (in meter) and weight (in kilogram) i.e. BMI= Weight/ Height2

  up to 24 weeks

• anthropometric measurement for child

  The anthropometric measurement for child were measured in mm by Auto CAD analysis for recorded photographs from sitting position.it include:1) elbow seat height: Measured with the elbow flexed at 90°, as the vertical distance from the bottom of the tip of the elbow to the student's seated surface, 2) shoulder height: Measured as the vertical distance from the top of the shoulder at the acromion process to the student's sitting surface,3) upper limb length: Difference between the elbow height and shoulder height.

  up to 24 weeks

• anthropometric measurement for school furniture

  The furniture dimensions were measured in mm by Auto CAD analysis for recorded photographs from sitting position.it include: 1) seat height: Measured as a distance from the floor to the highest point on the front of the seat, 2) seat depth: Measured from the back of the sitting surface of the seat to its front,3) backrest height: The vertical distance from the desk seat to the top edge of backrest, 4)desk- seat height: The vertical distance from the seat to the top of the front edge of the desk and 5) under surface of desk height: The vertical distance from the floor to the bottom of the front edge of the shelf under the writing surface..

  up to 24 weeks

Secondary Outcomes (3)

• Correlation between educational furniture dimensions and the user body dimensions

  through study completion, an average of 1 year.

• Head postures (angles)

  through study completion, an average of 1 year.

• scapular postures (displacement and elevation).

  through study completion, an average of 1 year.
