It may also be worth mentioning that the term 'tendinopathy' is used to more accurately describe this condition. Originally this injury was known as Achilles tendinitis or tendinosis, as it was thought to be caused by an inflammation of the Achilles tendon. These days, after further research into the pathology, it is realised that the condition is associated with a degeneracy of the fibrils that make up the tendon, and that inflammation is not the primary issue.
Overall the book contains mostly useful advice, written in a user friendly style. Its main value is in alerting the reader to the seriousness of the injury and how to avoid it developing into a more debilitating condition. However much of what is stated is well known basic health care and although the more specific advise given in Phase 2, will help rehabilitate mild cases of the ailment, I do not think it would be effective for curing long term chronic injuries. In particular his view on the "World's Worst Calf Stretch", flies in the face of more modern treatments that rely on such `drop step' techniques. I myself have benefitted from this enormously and would invite others to check out the extensive online literature (e.g. lulu.com/My Achilles Heel:), regarding such eccentric contractions and mechanotransduction.
