Isometric Contraction-Based Pain Modulation Versus Eccentric Strengthening in Treating Achilles Tendinopathy

ClinConnect Summary

This clinical trial is studying two different approaches to help people with Achilles tendinopathy, a common injury that causes pain in the back of the ankle. The trial compares two types of exercises: one that focuses on isometric contractions (holding a position without moving) and another that emphasizes eccentric strengthening (lengthening the tendon while it’s under tension). While eccentric strengthening has been the standard treatment for a while, researchers want to see if isometric contractions might help reduce pain more effectively, especially in the early stages of recovery.

To join the study, participants need to be diagnosed with Achilles tendinopathy through an MRI and have been experiencing symptoms for at least three months. They should be able to walk on their own and attend all scheduled treatment sessions. However, individuals with certain conditions, like severe ankle stiffness, previous surgeries on the ankle or lower limb, or specific systemic diseases, cannot participate. Those who take part can expect to learn more about their condition and potentially benefit from new exercise methods aimed at improving their recovery.
