LLD's and Achilles Tendinopathy

Sometimes, it doesn't matter whether it is long or short.

 Achilles tendinopathy .. there are many factors that can contribute. Have you considered leg length inequality? Generally speaking, People have a tendency to overpronate on the longer leg side and under prone only shorter leg side with strain on the medial and lateral aspects of the Achilles tendon respectively. It would make sense that this could be a contributing factor.

 "The mean inequality in length of legs (ILL) was 5 +/- 4 mm. Among the 48 patients with ILL > or = 5 mm, the side affected with ruptured tendon was longer in 48% of cases and shorter in 52%. "

Age and pathology can play a role with younger, healthy tender and having greater compliance.

Proprioception is impaired on the affected side of folks with Achilles tendinopathy. This is a "chicken and the egg" scenario. Did impaired proprioception cause the tendinopathy or is the tendinopathy causing the impaired proprioception? Probably, a little bit of both.
