What is Achilles Tendinopathy?
Mid portion Achilles tendinopathy is a common and often frustrating condition experienced by patients. It is characterized by the combination of pain and swelling in the Achilles tendon and impaired performance.1 The degree of pain and stiffness is usually a good indicator of severity of the tendinopathy.2

- The most common clinical diagnosis of Achilles overuse injuries is paratendinopathy and/or tendinopathy (55-65%), followed by insertional problems like retrocalcaneal bursitis and insertional tendinopathy (20-25%).3,4,5,6
- Non-insertional Achilles tendinopathy is characterized by pain which is worse at the beginning of & following sporting activity.7
- As the tendinopathy progresses, pain can be present during exercise and even at rest. Pain and stiffness in the morning may also be experienced and the duration of these symptoms can assist in diagnosing the severity.
- Pain experienced with mid portion tendinopathy is located 2-7cm above the calcaneus (often with fusiform thickenings.
Tendons transmit muscle forces to bone, allowing locomotion and enhancing joint stability. They respond to mechanical forces by changing their metabolism and their structural and mechanical properties. Inappropriate physical loading (either overuse or underuse) leads to tendon overuse injuries and tendinopathy.7 Although often attributed to over-use in sport, interestingly, in recent studies it was shown that 33% of patients with chronic Achilles tendinopathy are not physically active.8,9,10,11\
Clinical treatments focused on improving tendon structure or pathology are considered optimal interventions, but, as pain is often the clinical presentation, a case can be made for concentrating on reduction of pain as a valid outcome.19 Cook and Purdham’s continuum of tendon pathology provides a useful framework to tailor interventions dependent on the individual clinical presentation and pathology seen.19
Management of non-insertional Achilles tendinopathy is most commonly a conservative approach with loading protocols (predominantly eccentric exercises) being the first line treatment of choice. Systematic reviews have evaluated the results of eccentric loading of the injured tendon in tendinopathy,13-17 concluding although outcomes are promising, high-quality evidence is lacking.14
Shockwave therapy is another conservative approach that has been found to have similar efficacy to an eccentric exercise programme, and interestingly the combined use of shockwave therapy with eccentric exercises has been shown to produce greater improvement in pain and function compared with eccentric loading alone, or shockwave therapy alone.12
So how do you successfully combine both shockwave therapy and a loading protocol to treat Midportion Achilles Tendinopathy? Should the patient perform eccentric exercises before or after shockwave therapy? How long should you wait between treatments? How often should the exercise be performed and when should they be progressed?
