Objective
Knowledge of the normal value of thoracic kyphosis is essential during the assessment of the posture of the body. We measured thoracic kyphosis in 566 adolescents from Czestochowa (city in Poland) aged nine to fourteen years (275 girls and 291 boys).
Study design
The measurement of thoracic kyphosis was performed during clinical analysis of body posture using plurimeter-V by Rippstein [1]. The measurement was made in standing position and spontaneous relaxed posture. Each value represents mean and standard deviation from at least three replicate measurements.
