[Static and dynamic plantar pressure measurements in adolescents].
OBJECTIVE
This study was designed to determine normal values of pedobarography during standing and walking in adolescents in our country and to investigate correlations between demographic data and pedobarographic values.


METHODS
Fifty volunteers (25 girls, 25 boys; mean age 14 years; range 13 to 15 years) who were found to have healthy feet according to the AOFAS (American Orthopaedic Foot and Ankle Society) clinical rating system for the ankle and foot were enrolled into the study. Plantar pressures were measured during standing and walking tasks with the use of the Mini-Emed pedobarographic device.


RESULTS
Static measurements showed significantly higher pedobarographic values for right medial forefoot and toes in girls, and for left midfoot in boys (p<0.05). Overall, no significant differences existed between static pressure values for the right and left feet. The mean right medial foot pressure was higher than that of the contralateral foot in girls. There were no significant differences between the right and left feet in boys. Dynamic measurements showed a significantly larger contact area of the right foot in boys, and a significantly higher maximum plantar pressure of the left medial forefoot in girls (p<0.05). The strength of the correlation of body weight and body mass index was high with maximum plantar pressures (r=0.87 and r=0.83), and moderate with contact area of the foot (r=0.63 and r=0.59) in static measurements. Body weight (r=0.64) and body mass index (r=0.54) were moderately correlated with contact area of the foot in dynamic measurements.


CONCLUSIONS
Appreciation of normal plantar pressure values in adolescents is important in monitoring the development stages of foot, in the assessment of foot disorders, and in making proper footwear modifications in compliance with age.
