Extracorporeal Shockwave Therapy of Healthy Achilles Tendons Results in a Conditioned Pain Modulation Effect: A Randomised Exploratory Cross-Over Trial

Background. This study investigated whether ESWT applied to healthy Achilles tendons results in a conditioned pain modulation (CPM) effect. Methods. 3000 and 6000-shock dose radial ESWT was performed on dominant side Achilles tendon (random order over 5-9 days) among 20 healthy participants (75% male). Pressure was modulated throughout, producing >4/10 pain (10=worst imaginable). Bilateral pressure-pain … Continued
