AB Background: This study determined if the body mass index, dynamic plantar-pressures, plantar surface contactarea, velocity of the centre of pressure (COP), gastrocnemius equinus, and gastrocnemius soleus equines are relatedto calcaneal apophysitis (Sever’s disease) in athletic children.Methods: This case-control study examined 106 boys enrolled in a soccer academy, including 53 with Sever’sdisease and 53 age-matched healthy controls. The dynamic average and maximum peak plantar-pressures, plantarsurface contact-area, and velocity of the COP were evaluated with a digital pressure sensor platform. Goniometrywas used to measure the ankle dorsiflexion range of motion and thereby identify gastrocnemius equinus andgastrocnemius soleus equinus.Results: Participants with Sever’s condition had significantly higher BMI and peak plantar-pressures (maximum andaverage) at the heel (Cohen’s d > 3 for pressures) than the controls. Those with Sever’s disease also had significantlyslower velocity of the COP (Cohen’s d > 3). Boys with Sever’s disease were also 8 times more likely to have bilateralgastrocnemius equinus than disease controls.Conclusions: High heel plantar pressure and low velocity of COP are related to Sever’s condition in boys, althoughit is not clear whether these factors predispose individuals to the disease or are consequences of the disease.Gastrocnemius ankle equinus could be a predisposing factor for Sever’s condition.
