Patient FAQ

At Wetling, we understand that the need for advanced wound care can lead to questions and concerns for patients and their caregivers. We have created this section to help answer some of the questions you or your loved ones might have about our WMCS therapy, our product, and the services that might be performed during your treatment plan.


As with any medical device, it is important that you discuss this information with your healthcare provider to determine whether WMCS therapy is right for you. Should your healthcare provider not yet be aware of WMCS, please feel free to guide them to our website ( and/or contact us here. In certain markets, and in cooperation with our distribution partners, we may be able to provide your health care provider with free or subsidised evaluation period of the Wetling W200 device.

What is WMCS therapy?

WMCS stands for Wireless Micro Current Stimulation and is a non-invasive treatment to stimulate the human body’s own natural healing process. You can read more about WMCS here.

When is WMCS therapy used?

WMCS is used to accelerate the healing of chronic and acute wounds, as well as soft tissue injuries. To get the best results, WMCS should be used as early as possible after injury/surgery (in case of acute wounds) or in the early stages of a potential chronic wound.

Are there any harmful side effects to WMCS therapy?

There are no harmful side effects from WMCS treatment when used according to manufacturer’s instruction for use. However, in rare cases light itching, tingling and/or redness may occur during or shortly after the treatment, but these should disappear within a few hours.

Is WMCS therapy painful?

No. WMCS therapy is non-invasive and is painless when administered as intended.

How long does a WMCS session last?

A typical WMCS session lasts for 30-45 minutes and can treat an area of 300 cm2 in one single session.

What clinical trials have been done and what are the evidence?

There is extensive clinical evidence for the performance, efficacy, and safety of WMCS. The evidence is summarised in a Clinical Evaluation Report (refer here), which is the basis for the regulatory approvals and certifications (refer here) of the Wetling W200 device.

What certifications and approvals does the Wetling W200 have?

The Wetling W200 device has EC-certification (CE marking) as per MDD/93/EEC class IIa in Europe and separate local approvals for various markets in Asia Pacific. You can read more (here).

Is there any special preparation required before WMCS therapy?

Depending on the type of wound/injury, your clinician (doctor or nurse) will perform the necessary preparations.

In the case of a chronic or surgical wound, this may include removing the old dressing, cleaning, debridement, and/or irrigating the wound if required.

In the case of a burn injury, the first WMCS treatment should preferably be done immediately following the initial cleansing/debridement of the wound and before the primary dressing is applied. Subsequent treatments for burns may be done by only removing the secondary dressing. The primary dressing may not need to be removed until the skin has healed.

Should I sit or lie down during WMCS therapy?

Depending on the location of your wound/injury, your clinician (doctor or nurse) will decide the most comfortable position for treatment. Typically, this is either sitting down or lying on a treatment bed

How close should the WMCS device be to the treatment area?

The WMCS device is typically positioned about 10 cm (4 inches) above the treatment area.

Who can administer WMCS?

Administered in professional health care environment.
