Low-load resistance training with blood flow restriction for Achilles tendon pain

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effects of low-load resistance training with blood flow restriction (BFR-LLT) compared to high-load training (HLT) in patients suffering from chronic midportion Achilles tendinopathy (MAT). A total of 52 participants aged 18 to 50 will be randomly assigned to either the BFR-LLT or HLT group, undergoing a 12-week rehabilitation program with assessments of pain, tendon thickness, and function at baseline, 6 weeks, and 12 weeks. The training will be conducted at the University of Gran Rosario, with evaluations performed by a blinded physiotherapist to ensure objectivity.
