Measurement of plantar pressure data in children with clubfoot

It is becoming increasingly common for pedobarography to be used to aid treatment planning. While there is some consensus on use of this data in specific populations (for example diabetes in adults) there is little information on how it should be interpreted in those with paediatric orthopaedic conditions, such as clubfoot. This is due in part to a scarcity in the literature of “normal” reference data for children, as well as a lack of consensus on the clinical interpretation of deviations from normal data. The aim of this study was to determine if the plantar pressure distribution in children with clubfeet can reliably be distinguished from an age-matched, typically developing population.
Patients/materials and methods
Substantial variation in pressure distribution was found in the TD population. Despite this, almost all CF subjects demonstrated significant differences to age-matched TD data. This suggests that pedobarography provides adequate sensitivity for assessing this population. “Normal” reference data may be used as a comparison (similar to other gait data) but care should be taken that this is appropriately age-matched. Markers placed on the foot were used to automatically mask the footprint for this study, allowing accuracy of masking to be maintained, even in the presence of abnormal foot shapes. This needs to be taken into consideration when assessing data from a clubfoot population.
