Heel pain in children

Status: Ongoing (January 2021 - 2022)

A cohort study among children with Sever’s Disease in podiatry practice.

What we do

About our project

Sever’s disease causes heel pain during and/or after physical activity in physically active children between the ages of 8 and 15. This condition resolves by itself when the growth plate fuses, but has a large variability in symptom duration. There is no literature available on the prognosis of the disease. The absence of prognostic factors and the large variability in symptom duration make it difficult to estimate the prognosis for these patients.

To determine the prognosis of patients with Sever’s disease in podiatry practice.

Cohort study of children aged 6 to 16 years with Sever’s disease that are recruited in podiatry practices and all followed for a period of 12 months. In order to be eligible to participate in this study, a subject must meet all of the following criteria: Aged between 6 and 16 years
Complaints of the heel with a positive squeeze test (pressure at medial and lateral side of calcaneus). Children will be recruited in 186 practices from RondOm podiatry. Monthly questionnaires will be send to all children.
