Shockwave Therapy of Chronic Achilles Tendinopathy

May 27, 2015 updated by: Northern Orthopaedic Division, Denmark

Shockwave Therapy of Chronic Achilles Tendinopathy. A Double-blind, Randomized Clinical Trial of Efficacy

Chronic Achilles tendinopathy is a painful condition with frequently unsatisfactory results of conservative treatment. Extracorporal Shock Wave Therapy (ESWT) has been introduced in the management of various soft tissue conditions. The objective of the study was to investigate the effect of supplementary ESWT versus placebo to conservative treatment of chronic Achilles tendinopathy.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Chronic Achilles tendinopathy is a common disability of the foot during walking and running. Avoiding of painful activities, correction of malalignment by arch support, stretching exercise and eccentric training combined with non-steroidal anti-inflammatory pain killers are the standard treatment regimen (Wilson 2005). However, evidence to support these modalities is sparse (McLauchlan 2001).

Extracorporal shock wave therapy (ESWT) originally used for treatment of renal stones became popular in the last decade for treatment of different soft tissue disorders including calcifying tendinopathy in the rotator cuff, humeral epicondylitis and plantar fasciitis (Haake 2001, Ogden 2001, Chung 2002, Gerdesmeyer 2003, Speed 2004). It is now worldwide employed and FDA-approved for the treatment of plantar fasciitis. However regarding both calcifying tendinopathy in the rotator cuff, humeral epicondylitis and plantar fasciitis the results are conflicting (Rompe 1996, Boddeker 2001, Hammer 2002, Schmitt 2002, Gross 2003, Haake 2003, Pleiner 2004, Chung 2005). A series of randomized studies on ESWT for soft tissue disorders have been reported (Rompe 1997, Krishek 1998, Loew 1999, Rompe 2001, Haake 2001, Hammer 2002, Schmitt 2002, Gerdesmeyer 2003, Gross 2003, Haake 2003, Pleiner 2004, Chung 2005, Costa 2005) only four reporting significant effect of ESWT (Rompe 1997, Krishek 1998, Loew 1999, Gerdesmeyer 2003), and only one randomised studies for chronic achilles tendinopathy (Costa 2005). Two uncontrolled (Perlick 2002, Lakshmanan 2003) and one controlled (Furia 2005) series introduce ESWT for chronic Achilles tendinopathy. The results of these papers are seriously conflicting. Some authors include training and others not. Since eccentric training has documented effect (Alfredson 2000) other conservative treatments should be introduced as a supplement.

We investigated in a double blind randomized trial the supplementary effect of ESWT to enhance recovery of Achilles tendinopathy. We investigated, firstly, the effect on AOFAS score and secondly the effect on pain.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No
