BACKGROUND: There is no consensus regarding the treatment of Achilles insertional @entity924 . Eccentric training remains the main choice in the conservative treatment of this illness; however, the good results in the management of @entity924 were not replicated in the insertional condition. Low energy shock wave therapy has been described as an alternative to these @entity1 , but has yet to be empirically tested. HYPOTHESIS: Shock wave therapy, adjunctive to the eccentric strengthening protocol, will improve measures of @entity158 and function. DESIGN: Double blind, placebo-controlled, parallel groups, randomised clinical trial. MATERIALS AND METHODS: 93 @entity1 with a diagnosis of chronic insertional @entity924 , referred from primary or secondary healthcare services, will be assessed and enrolled in this study. They will be divided into two groups (randomised by sequentially numbered identical envelopes, which will be administered serially to @entity1 ), one containing the combination of low energy shock wave and eccentric exercises, as treatment and the other comprehending the exercises and the placebo treatment (an apparatus placed in the therapeutic head). The assessments will occur in 2, 4, 6, 12 and 24   weeks. @entity1 will be evaluated primarily by the Victorian Institute of Sport Assessment-Achilles questionnaire and secondarily by the visual analogue scale, Algometry, the American Orthopedic Foot and Ankle Society scale, the Foot and Ankle Outcome Score and the 12-item Short Form Health Survey. We will use comparison of two proportions via relative frequency analysis, the Pearson Correlation the   (2) test and the analysis of variance for statistical analyses. DISCUSSION: This study intends to demonstrate if the association of the eccentric exercise programme with the shock wave therapy can produce good results regarding the treatment of the Achilles insertional @entity924 . In an attempt to prevent the high costs and complications associated with the surgical intervention, we will try to prove this combination as a viable therapeutic option in the conservative management of this prevalent condition. The strengths of the study are the design and the novelty of the combination of methods. The main limitation is the short follow-up course. ETHICS AND DISSEMINATION: The study is registered in the Clinical Trials database (protocol number: 8094833648737701) and was approved by the University Ethics Committee (number: 1373481). TRIAL REGISTRATION NUMBER: 8094833648737701 (NCT02757664); Pre-results.
