WMCS for Chronic Wounds

​

Wounds that do not heal within 3 months are normally referred to as Chronic or “hard-to-heal” wounds. There are many types of Chronic Wounds, including:

​

  • Diabetic foot ulcers (Neuropathy/Angiopathy)

  • Pressure ulcers / Decubitus ulcers

  • Venous leg ulcers

  • Arterial leg ulcers

  • Mixed leg ulcers

  • Leg ulcers of lymphological origin

  • Leg ulcers of dermatological origin (e.g. pyoderma)

  • Other, e.g. post operative healing disorders (e.g. after heart surgery)

 

The alarming global growth of Chronic Wounds

​

As a result of the global epidemic of non-communicable diseases such as Diabetes and Cardiovascular disease, the Compound Annual Growth Rate (CAGR) of Chronic wounds globally for 2012-2020 is estimated at an alarming 7.6%.

According to estimates, the global prevalence (annual new incidences) and growth rate of some of the more common Chronic Wounds are:

WMCS treatment of Chronic Wounds:

​

Before starting WMCS treatment, it is important to correctly diagnose the type of chronic wound and adapt the correct primary treatment protocol.

​

  • Examine and treat the cause of wound.

  • Manage the pain.

  • Examine the periwound skin.

  • Take a swab (for obtaining a wound culture).

  • Examine wound exudate.

Typical adjunctive WMCS treatment plan for Chronic Wounds:

​

  1. Cleansing/Debridement of the wound (if needed)

  2. WMCS treatment for 45-60 min with 1.5 μA

  3. Apply wound dressing

  4. Repeat 1-3 above 3 times/week after irrigation of the wound

The healing times of Chronic Wounds depends on many factors, such as the age and size of the wound, the existence of infection and/or pain, the underlying cause of the wound (and if this cause can be eliminated or improved), sufficiency of diagnostic measures and the patient’s compliance to medical procedure/advice.

​

Expected results from WMCS therapy for Chronic Wounds:

​

  • Healing time drastically reduced, typically a factor of 2-3 times faster than with traditional wound treatment.

  • Non-invasive treatment

  • Patient is free of pain faster

  • Excellent tolerability – no significant side effects 

  • First positive effects can be seen already 1-2 weeks after starting treatment

  • Treatment can be carried out in combination with other applied methods

  • Time saving for patient and medical staff

  • Device is convenient in its transportation and application (e.g Home care is possible)

  • Acceleration of wound healing also in “untreatable“ patients

  • Increased application areas compared to previous providers of traditional electrical stimulation (ES)

WMCS references for Chronic Wound Treatments

​

Arguably the most comprehensive research to date of WMCS for Chronic Wounds has been done by Dr Peter G Wirsing at Wundzentrum in Ostalb-Klinikum Aalen, Germany. Though all forms of Chronic Wounds seem to respond very favourably to WMCS, notably wounds with underlying vascular diseases (venous/arterial/mixed leg ulcers, diabetic foot ulcers) typically have a faster response to WMCS treatment. It has been noted that WMCS does not only build up the "electric field" ("Current of Injury"), but also supports the oxygenation of the wound tissue against hypoxia.

​

By comparison, wounds caused by vasculitis or of dermatological origin may demonstrate a slightly delayed response to WMCS treatment (2-3 weeks).  However, after this slightly "slower start" these wounds will also respond well to WMCS and heal faster than with traditional wound management.

​

Various articles have been published around the work done by Dr. Wirsing, among the most interesting of which is one in relation to diabetic foot ulcers published 2014 in the International Wound Journal:

​

Peter G Wirsing et al. “Wireless micro current stimulation – an innovative electrical stimulation method for the treatment of patients with leg and diabetic foot ulcers”.  International Wound Journal ISSN 1742-4801

 

Amongst other specialists that have published positive results with WMCS are;

  • Thomas Zehnder, Marilise Blatti and Sandra Friedli at Spital Thun (Hospital of Thun) in Switzerland; 

  • Konstantinos Poulas, Manousos E. Kambouris and George Lagoumintzis at University of Patras, Dept of Pharmacy in Greece.

Clinical Trials

​

A double blind, placebo-controlled trial regarding Wireless Micro Current Stimulation (WMCS) as adjunctive chronic leg ulcer treatment has recently been completed at Bronovo Hospital in the Hague, Netherlands. Principal investigator: dr. M. Larsen, MD, Phd. This trial was completed in 2018 and publication is expected in Q1 2019. The unofficial feedback is that results are consistent with earlier claims.
