Brief Summary

Background: There is no consensus regarding the treatment of insertional tendinopathies. The good results of the eccentric training in the management of the non-insertional Achilles tendinopathy were not reproducible in the insertional disease. Shock wave therapy is described as an alternative to these patients. Hypothesis: The shock wave therapy allied to the eccentric strengthening protocol presents better results that the eccentric strengthening associated to placebo. Design: Double blinded (outcome assessor and patient) randomized clinical trial, with the use of placebo, in parallel groups. Materials and Methods: Nine-three patients with chronic insertional tendinopathy will be enrolled in a randomized trial. Participants will be divided in two groups, one containing the combination of shock wave and eccentric exercises as treatment and the other comprehending the exercises assembled to placebo. The assessment of outcomes will occur in 2, 4, 6, 12 and 24 weeks of the beginning of the study. Patients will be evaluated for pain, activity and function by the VISA-A (the Victorian Institute of Sport Assessment-Achilles \[VISA-A\] questionnaire).

PLACEBO COMPARATOR

Placebo associated with eccentric exercises rehabilitation program.

Other: Eccentric ExercisesDevice: Placebo

Interventions

Appliance of radial shock waves with the BLT600 equipment (BTL Medical Technologies - Canada), the intensity being 2000 to 3000 pulses, 7 to 10Hz of frequency, and 1,5 a 2,5Bar of intensity per application; Appliance on the first day of treatment (D0), repeated on the second week after the first intervention (2nd week) and four weeks after the first intervention (4th week).

Also known as: radial shock waves
Shock wave plus eccentric exercises

12 weeks, starting on the same day of the first appliance. The patient will practice the exercises standing on tiptoes and will perform exercises of passive ankle extension (dorsiflexion), three series of 15 repetitions, with the knee stretched, and three series of 15 repetitions with the knee flexed by 20 degrees.
