Extracorporeal Shockwave Treatment for Greater Trochanteric Pain Syndrome — ESTATE  

Mobility Limitation Clinical Trial

Official title: Extracorporeal Shockwave Treatment in the Greater Trochanteric Pain Syndrome. Multicenter, Randomized, Controlled Clinical Trial

Status Completed

Clinical Trial Summary

Greater trochanteric pain syndrome (GTPS) is characterized by pain over the greater trochanter, which can refer down the lateral aspect of the hip. Historically, conservative treatments such as rest/activity modification, anti-inflammatory medication, physiotherapy and local corticosteroid injection, are employed as first-line management, with some refractory cases requiring surgical intervention.

Acknowledging the unpredictable response and frequent recurrences associated with traditional non operative treatment, the risks and prolonged rehabilitation associated with surgery, and the favorable results from prior studies involving radial pressure waves as a treatment for GTPS, the aim of this study is to investigate the dose-related effect of focalized shockwave treatment at different total energy influx in patients with chronic GTPS.

Clinical Trial Description

Shockwave therapy (SWT) has been used successfully since the late 1980s for the management of various musculoskeletal disorders including plantar fasciopathy, achilles tendinopathy, shoulder calcific tendinopathy, and lateral epicondylitis. Although there are some negative trials, there are now many randomized, double-blinded, clinical trials that support the use of SWT for the above conditions. Acknowledging the unpredictable response and frequent recurrences associated with traditional non operative treatment, the risks and prolonged rehabilitation associated with surgery, the recognition of gluteal tendinopathy as a potential source of pain, and the favorable results from prior studies involving radial pressure waves as a treatment for GTPS, the aim of this study is to investigate the dose-related effect of shockwave treatment at different total energy by adjusting the energy flux density (EFD) in patients with chronic GTPS. The shockwave has been widely recognized in literature as a biological regulator, currently the biological effects of shockwaves can be obtained using lower energy than in the past.

While the intensity or delivered energy is considered by some researchers to be a key factor for successful treatment, in current literature reviews, debate continues over the appropriate energy intensity and the total delivered energy that should be applied to the tissue.

Therefore, higher intensity treatments usually require local anesthesia, which is known to reduce the efficacy of the treatment. Furthermore, some animal tests reported that an influx of energy of over 0.60 mJ/mm2 can cause permanent damage on the tendon. On the other hand, low-intensity energy is safer but has the disadvantage of lower treatment effects.

The investigators hypothesize that a very low intensity protocol of ESWT has different effects on pain and function than a conventional protocol in a patient with GTPS syndrome. ;
