What is the purpose of this trial?

This trial tests whether Intermittent Electrical Stimulation (IES) can heal pressure sores, painful wounds caused by prolonged immobility. The trial compares two groups: one receiving IES treatment with small electrical pulses and another receiving standard wound care. It targets individuals with stage 1 or 2 pressure sores on their lower back or buttocks who can consent to participate. As an unphased trial, this study provides a unique opportunity to explore innovative treatment options for pressure sores.

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that Intermittent Electrical Stimulation is safe for treating pressure sores?

Research shows that electrical stimulation often treats wounds like pressure sores. Studies have found this method generally safe, helping wounds heal faster and reducing pain. One study discovered that tiny electrical currents improved healing compared to standard treatment alone. Another study suggested that electrical stimulation might increase the number of pressure sores that heal and speed up the healing process.

Although specific information on the treatment used in this trial is limited, similar electrical stimulation methods have a good safety record. These treatments are non-invasive, avoiding surgery or injections, which usually means fewer risks. Overall, research suggests that patients tolerate electrical stimulation well, with few side effects reported. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about Intermittent Electrical Stimulation (IES) for pressure sores because it offers a new, non-invasive way to prevent and manage these wounds. Unlike standard care, which relies on wound dressings, repositioning, and other traditional methods, IES uses charged pulses to stimulate the gluteus maximus muscles. This stimulation occurs at a frequency of 30 Hz for 10 seconds every 10 minutes, potentially improving blood flow and reducing the risk of sores developing without interrupting daily activities. By targeting muscle activity directly, IES could enhance healing and offer a novel approach to pressure sore management.

What evidence suggests that Intermittent Electrical Stimulation is effective for pressure sores?

Research has shown that Intermittent Electrical Stimulation (IES), which participants in this trial may receive, can help heal pressure sores—wounds that develop from prolonged immobility. Studies have found that gentle electrical currents can accelerate healing by promoting faster tissue regeneration. This method has benefited people with spinal cord injuries in treating and preventing these sores. Overall, evidence suggests that IES effectively supports the healing of pressure injuries. ^{1 5 6 7 8}

Are You a Good Fit for This Trial?

This trial is for patients with new or existing stage 1 or 2 pressure ulcers near the tailbone or hip area, in both ICU and non-ICU settings. Participants must be able to consent, or have someone who can consent for them. It's not for those with certain fractures, muscle breakdown (rhabdomyolysis), heart device implants like pacemakers, skin issues that prevent electrode use on the buttocks, or a BMI over 40.

Inclusion Criteria

I have a new or existing mild to moderate pressure sore on my lower back or buttocks.

I can give my own consent or have someone who can consent for me.

Exclusion Criteria

I have unstable fractures in my spine, pelvis, or hip.

I have a permanent pacemaker or AICD, or I might need an external pacemaker.

I have had rhabdomyolysis.

What Are the Treatments Tested in This Trial?

Interventions

• Intermittent Electrical Stimulation (IES)

Trial Overview

The PROTECT 2 Study tests if using an Intermittent Electrical Stimulation (IES) system along with regular turning every two hours helps heal pressure injuries better than just turning patients every two hours. This study randomly assigns participants to either treatment group across multiple centers.

How Is the Trial Designed?

Group I: Intermittent electrical stimulation system (IES) treatment Group Active Control 1 Intervention

Charged pulses will be administered to bilateral gluteus maximus through surface electrodes. Stimulation occurs at 30 Hz for 10 seconds every 10 minutes.

Group II: Standard of care Group Active Control 1 Intervention

Standard inpatient nursing practice for wound care, wound care prevention, and any other wound care or plastic surgery treatments deemed appropriate as per usual care.

Intermittent Electrical Stimulation (IES) is already approved in United States, European Union, Canada for the following indications:

Functional electrical stimulation (FES) applied to the quadriceps in seated spinal cord injured (SCI) subjects significantly reduced ischial pressures, with average drops of 44 mmHg on the right and 27 mmHg on the left buttock.

The effectiveness of FES in reducing pressure sores was more pronounced in subjects with larger knee moments, suggesting that FES could be a valuable preventive tool for managing pressure sores in SCI patients.

In a study involving 203 patients with knee osteoarthritis, all treatment groups (TENS, IFCs, SWD) showed significant improvements in pain and function, but there were no major differences in effectiveness among the active treatments compared to sham interventions.

Patients receiving active treatments had a significantly lower intake of paracetamol compared to those in sham groups, indicating that physical therapy modalities may enhance pain relief beyond exercise and education alone.

An educational program significantly improved healthcare providers' knowledge about using electrical stimulation (E-Stim) for treating pressure injuries, with knowledge scores increasing from 55.9% to 78.4% after the online modules and remaining at 78.0% after the hands-on workshop.

While knowledge increased, hands-on workshops were essential for positively changing attitudes towards E-Stim use, indicating that practical experience is crucial for effective implementation in clinical practice.

Electrical muscle stimulation (EMS) effectively reduces pressure under the ischial tuberosity, which is crucial for preventing pressure sores, as shown in tests with three able-bodied subjects.

The study indicates that EMS can redistribute pressure on seating surfaces without causing fatigue in able-bodied individuals, suggesting its potential for safe, long-term use in pressure sore prevention.

Intermittent electrical stimulation (IES) was tested in a study involving rats to prevent deep tissue injury (DTI) caused by pressure ulcers, showing that all IES treatment paradigms significantly reduced muscle damage compared to conventional pressure relief methods.

Conventional pressure relief, similar to a wheelchair push-up every 10 minutes, was found to be inadequate for preventing DTI, highlighting the potential of IES as a more effective intervention for preventing deep pressure ulcers.

In a study involving 30 healthy volunteers, interferential currents (IFC) were found to significantly reduce pain intensity compared to sham electrotherapy, indicating its potential effectiveness for pain management.

However, there was no significant difference in pain relief between IFC and transcutaneous electrical nerve stimulation (TENS), suggesting that both methods may offer similar analgesic effects.
