Great information on loading for the different types of Achilles pain. Mid portion vs insertional.
How should we rank exercise parameters in tendinopathy? 🥇🥈🥉
A recent Delphi study in asked international experts in Achilles Tendinopathy (AT) to complete a 3 round survey to help us find the answer.
For mid-portion AT contraction intensity was considered most important as there is evidence high loads are required to create tendon adaptation, enhance tendon stiffness and improve muscle strength.
Time under tension was also considered important as longer contractions are also thought to increase tendon adaptation.
Contraction type (eccentric only, concentric + eccentric, isometric etc) was considered less important as in studies they appear to result in similar clinical outcomes and tendon adaptation.
For insertional AT range of dorsiflexion was ranked as most important as loading in greater dorsiflexion is often provocative for symptoms. Contraction intensity came second so was also considered important.
In rehab of insertional AT we can address both by first loading outside of painful dorsiflexed positions and progressing load based on goals and symptom response. When symptoms are less irritable dorsiflexion during loading can be gradually increased (see our graphic on Pringels et al. 2025 for more info on this).
Surprisingly pain wasn’t top of the list in this study but it still needs to be considered. The paper advocated monitoring pain response, during exercise, immediately after and the next day to ensure rehab is at a manageable level.
