The goal was to improve outcomes of treatment of chronic non-healing recurrent leg ulcers in complex medical problems patients

In case study, multiple patients (4 to be demonstrated with photos) were treated with advanced modalities at outpatient wound clinic for months. Wounds were in very slow healing to stalled conditions.

1-2 x week non-contact, low frequency ultrasound treatments were added to regiment.

changes in wounds were noted after first 2-3 treatments - inflammation decreased, pain decreased, biofilm and fibrous tissue built up decreased, need for surgical debridement was eliminated.

Advanced wound care modalities were used, as prior to treatment, intermittent POAB were given as needed.

Only conservative debridement was used.

Resulted in reduction on pain, significant reduction in wounds size and healing in half of expected time, leading to financial savings as well as reduction of infections and risks of hospitalizations.

Criteria for use and patient/provider requirements were created


In summary, based on success using non-contact, low frequency ultrasound treatments for the treatment of chronic leg ulcers in patients with complex health issues, we have found the application of non-contact, low frequency ultrasound therapy to be a safe and effective treatment option for chronic leg ulcers. This therapy led to substantially improved wound healing and markedly decreased pain. We believe this therapy to be a novel and promising method for the treatment of chronic leg ulcers resulting in faster healing, fewer infections and hospitalizations.
