Scientific titleAchilles Tendinopathy Management: a randomised controlled trial comparing platelet-rich plasma with an eccentric loading programme
Study acronymATM
Study objectivesThere is no difference in Victorian Institute of Sports Assessment - Achilles (VISA-A) scores at 6 months between patients initially managed with platelet-rich plasma injections compared to patients managed with an eccentric loading programme.
Ethics approval(s)Coventry Research Ethics Committee, 20/03/2009, ref: 09/H1210/18
Health condition(s) or problem(s) studiedAchilles tendinopathy
InterventionIntervention:
Platelet Rich Plasma Injection. The procedure will involve taking 52 ml of whole blood combined with 8 ml of an anti-coagulant which will be immediately centrifuged at 2400 for 12 minutes. After centrifugation the platelet layer (approximately 3 - 5 ml) will be extracted using a syringe and then injected into the Achilles tendinopathy.

Comparison:
Eccentric Loading Programme, involving two exercises. The first involves the patient being in a standing position with the heel over the edge of a step with the legs straight. The patient then slowly lowers their heels beyond the level of the step. The second exercise follows the same sequence but with the knee slightly bent, to maximise activation of the soleus muscles. These exercises are performed three times a day, 7 days a week for 12 weeks and are progressed as pain allows by adding weight via a back pack.
