Clinical evidence for low intensity extracorporeal shock wave therapy (Li-ESWT)

Low intensity extracorporeal shock wave therapy has been studied extensively and a number of double blind studies have been undertaken, with more underway, to investigate its potential to treat erectile dysfunction in various cohorts. Studies are registered with the National Institutes of Health on ClinicalTrials.gov here. Over 19 studies involving shock waves have been registered and are listed here. The therapy is currently approved in over 20 countries and many hundred clinics worldwide. The protocols and the type of device are significant – see the devices/technologies here. Focused and radial shock waves have different effects.

Men’s Power-Pressure Wave Erectile Regeneration-Therapy: an Early Assessment

Jason Perelman and Vaughan Daniels Hepnar – 2017

This study was to evaluate low intensity extracorporeal shockwave therapy (LISWT) for Erectile Dysfunction (ED) used as a first line treatment in many parts of the world as a viable alternative to oral, on-demand, phosphodiesterase type 5 inhibitors (PDE5i). It concluded that non-invasive low intensity shockwave therapy (LISWT) has been shown to significantly improve erectile function in men previously PDE5i dependent.

Effects of Next-Generation Low-Energy Extracorporeal Shockwave Therapy on Erectile Dysfunction in an Animal Model of Diabetes

Hyun Cheol Jeong, et al, November 2017  

Research into the effectiveness of treatments of ED using ESWT can be more systematic using animal models. This study using three cohorts of 10 individuals conducted in Korea demonstrated that electromagnetic cylinder ESWT, the technology utilized in SONICWAVE treatment, helps restore smooth muscle function. Histological and immunohistochemical study shows restored levels of vascular endothelial growth factor (VEGF), endothelial nitric oxide synthase (eNOS), platelet endothelial cell adhesion molecule-1, cyclic guanosine monophosphate, and neuronal nitric oxide synthase (nNOS) expression levels.

Low-Intensity Shockwave Therapy Improves Hemodynamic Parameters in Patients With Vasculogenic Erectile Dysfunction: A Triplex Ultrasonography-Based Sham-Controlled Trial.

D. Kalyvianakis, I. Mykoniatis, July 2017

A double-blinded, randomized, sham-controlled trial of forty-six patients with ED thirty of whom underwent low-intensity extracorporeal shockwave therapy (LI-ESWT). The study confirmed the beneficial effect of LI-ESWT on penile hemodynamics and the beneficial effect of this treatment up to 12 months. The result is objective and subjective documentation of the value of this treatment modality for men with vasculogenic ED.

Can low-intensity extracorporeal shockwave therapy improve erectile dysfunction? A prospective, randomized, double-blind, placebo-controlled study

Anne B. Olsen, Marie Persiani, Sidsel Boie, Milad Hanna & Lars Lund, Dec 2014

This placebo-controlled study over 5 weeks shows that 57% of the men who suffered from erectile dysfunction had an effect from LI-ESWT. After 24 weeks, seven (19%, active group) and nine (23%, active placebo group) men were still able to have intercourse without medication. This study shows a possible cure in some patients, but more research, longer follow-up in the placebo group and an international multicentre randomized study are needed.
