Good Results with Painful Eccentric Calf Muscle Training for Patients with Painful Midportion Achilles Tendinosis Implications for New Treatments

Painful eccentric calf muscle training was demonstrated to be a good treatment model for chronic painful midportion Achilles tendinopathy. The model using the concept with painful tendon loading was completely against the world wide used model for treatment of tendinopathy were pain-free tendon loading was used. The good clinical results using this model raised our interest to perform intensive research on the pain-mechanisms associated with chronic painful Achilles tendinopathy.
