A stubborn injury that plagues many athletes, especially runners, is achilles tendinopathy. While rest may alleviate the pain in some individuals, as soon as activity is resumed, the symptoms often return.
As with many tendinopathy pathologies, achilles tendinopathy is often diagnosed as tendinitis and treated improperly. It has been shown that neovascularization is abundant in these structures and is not necessarily an inflammation issue (a topic we will examine more closely in the near future!). As with any other injured individual, they will present with many impairments that should be treated regularly (stretching, strengthening, etc.), but there are certain interventions that have been shown to have higher evidence.
Low-Level Laser Therapy (LLLT) is an intervention that is becoming more prominent today in treating many different pathologies, one of which is achilles tendinopathy. In the study we looked at, there was no difference between eccentric exercises + placebo and eccentric exercises + LLLT (actually the placebo group performed better in one of the outcomes!). Consider this evidence when choosing your interventions.
As you might have expected, eccentric exercises have been shown to be the best treatment method for patients with achilles tendinopathy. Even after 5 years of treatment, improvements were shown; although, some pain was still present in some individuals. One of the issues with using eccentric exercises for individuals with achilles tendinopathy that has become prevalent is the effectiveness for those with insertional vs. mid-portion achilles tendinopathy. Insertional achilles tendinopathy results in the tendon being most painful where it attaches to the calcaneus; mid-portion achilles tendinopathy is proximal to that. The studies have shown high evidence in regular eccentric exercises (loading into dorsiflexion) for mid-portion pain, but not insertional pain. However, there has been recent research that shows a modification of the exercise can improve the results of insertional pain. Perform the eccentric exercise the normal way, except do not load into dorsiflexion. Approximately 2/3 of the sample showed improvements!
Another alternative treatment method that is becoming more well-known involves using autologous-combined plasma injections combined with standard treatments-wearing a pneumatic boot, receiving ultrasound, and eccentric exercises. Occasionally, you hear about professional athletes receiving this type of treatment for other joints in Europe, since it is not usually performed in the U.S. While the study is still preliminary, it's still something to keep your eye on in the future!
