About

These calculators for normative values of Achilles tendon thickness and normative values of the Heel Rise Endurance Test (HRET) are a result of the REVEAL trial, which was conducted at the outpatient departments of the Erasmus MC University Medical Centre (Rotterdam, the Netherlands) and the University of Leicester (Leicester, United Kingdom) in collaboration with the University of Waikato (New-Zealand).

With the Achilles tendon thickness tool we aim to improve personalised patient care and help healthcare providers distinguish between ultrasonographic features of Achilles tendinopathy and normal morphological changes. The HRET tool aims to help clinicians to monitor personalized trajectories of recovery and to provide well-informed rehabilitation guidance.

Seth O’Neil, PT, PhD

Seth O’ Neill is a Physiotherapy Lecturer at the University of Leicester, balancing his academic role with clinical practice. His extensive research background includes a PhD focused on tendinopathy, where he investigated the prevalence rates of tendinopathy among UK runners and delved into a comprehensive exploration of the associated risk factors related to Achilles tendinopathy. His subsequent research endeavours have offered a deeper analysis of how tendinopathy impacts the plantar flexors, specifically examining the alterations in strength and endurance and identifying the key plantar flexor muscles involved. Notably, his work has shed light on the significant role of the soleus muscle in human Achilles tendinopathy, subsequently leading to further investigations into calf injuries in sports.
