What is the purpose of this trial?

This trial tests whether pulsed electromagnetic field (PEMF) therapy can reduce pain after shoulder or knee surgery. Participants will receive either an active PEMF device or a placebo (inactive) device post-surgery to determine if the treatment eases pain and reduces the need for pain medication. Individuals undergoing shoulder or knee surgery who have not taken NSAIDs (nonsteroidal anti-inflammatory drugs) for a week before surgery might be suitable candidates. The trial aims to assess the effectiveness of PEMF therapy in improving recovery and reducing pain. As an unphased trial, it offers participants the chance to contribute to innovative research that could enhance post-surgical recovery.

Will I have to stop taking my current medications?

The trial requires that you stop taking NSAIDs (non-steroidal anti-inflammatory drugs) for one week before surgery, but low-dose aspirin is allowed. If you are taking corticosteroids, antineoplastic, immunostimulation, or immunosuppressive agents, you must stop them 30 days before surgery, except for asthma and eye medications.

What prior data suggests that this PEMF therapy is safe for postoperative pain management?

Research shows that the Endonovo SofPulse device, which uses pulsed electromagnetic field (PEMF) therapy, is generally easy for patients to handle. Studies have demonstrated that this technology is FDA-cleared, indicating it has met safety standards for treating acute pain. Past trials found that PEMF therapy significantly speeds up healing and reduces the need for pain medications, without major side effects.

Although detailed information on side effects isn't provided, FDA clearance for other uses suggests it is considered safe. This is reassuring for those considering participation in a trial with this treatment. Remember, all medical treatments can affect people differently, so discussing any concerns with a healthcare professional is important. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Unlike traditional pain management options for postoperative pain, which often rely on medications like opioids or NSAIDs, Endonovo SofPulse uses a novel approach with pulsed electromagnetic field (PEMF) therapy. This non-invasive treatment is unique because it targets pain and inflammation directly at the cellular level, potentially reducing the need for pharmaceuticals and their associated side effects. Researchers are excited about SofPulse because it offers a drug-free alternative that could accelerate recovery and improve patient comfort without the risks of addiction or adverse reactions associated with conventional pain medications.

What evidence suggests that PEMF therapy is effective for reducing postoperative pain?

Research has shown that pulsed electromagnetic field (PEMF) therapy, such as Endonovo SofPulse, can reduce pain after surgeries. In this trial, participants will receive either the active Endonovo SofPulse device, which emits a pulsed electromagnetic field, or a placebo device that does not emit PEMF. Studies found that SofPulse significantly decreased post-surgery pain. Previous patients reported less pain and better recovery with PEMF therapy. This suggests that the Endonovo SofPulse device may ease pain after shoulder or knee surgeries. ^{1 3 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• Endonovo SofPulse

Trial Overview

The study tests if PEMF therapy using Endonovo SofPulse reduces pain after orthopedic surgery on the shoulder or knee. It measures how much it lowers pain levels at day 10 post-surgery using a visual scale and checks medication usage and physical function outcomes.

How Is the Trial Designed?

Group I: Active PEMF Group Active Control 1 Intervention

Participants will have a 1 in 2 chance to get the active treatment device post-operatively. The device will be attached to the post-operative dressing. The device is an Endonovo SofPulse that emits a pulsed electromagnetic field (PEMF). Single blind randomization.

Group II: Placebo PEMF Group Placebo Group 1 Intervention

Participants will have a 1 in 2 chance to get the placebo treatment device post-operatively. The device will be attached to the post-operative dressing. The Endonovo SofPulse placebo device does not emit a pulsed electromagnetic field (PEMF). Single blind randomization.

Published Research Related to This Trial

Pulsed Electro Magnetic Fields (PEMFs) treatment has been shown to be safe and well-tolerated in patients undergoing joint replacement surgery, with no reported adverse effects and good patient compliance.

The use of PEMFs in the early days post-surgery can effectively control inflammation and improve functional recovery, suggesting it could be a beneficial addition to standard post-operative care for hip, knee, or shoulder arthroplasties.

Role of pulsed electromagnetic fields after joint replacements. Lullini, G., Cammisa, E., Setti, S., et al.[2020]

Pulsed electromagnetic field therapy significantly reduced postoperative pain by 57% at 1 hour and 300% at 5 hours after surgery, leading to a 2.2-fold decrease in narcotic use among patients.

The therapy also lowered levels of IL-1 beta in wound exudates by 275%, suggesting a mechanism involving nitric oxide signaling that may enhance wound healing.

In a pilot study involving 27 patients with osteoarthritis, those treated with pulsed electromagnetic fields (PEMF) showed an average improvement of 23-61% in clinical symptoms, compared to only 2-18% improvement in the placebo group.

No toxicity was observed in patients receiving PEMF treatment, indicating it is a safe option, and the results suggest that PEMF could be an effective method for alleviating symptoms of osteoarthritis, warranting further research.

In a study of 72 women undergoing elective C-sections, those receiving pulsed electromagnetic field (PEMF) treatment reported significantly lower postoperative pain levels and required 1.9 times fewer analgesics in the first 24 hours compared to the placebo group.

Patients treated with PEMF also showed improved wound healing by the seventh postoperative day, with fewer signs of complications such as exudate, erythema, or edema, indicating its potential as an effective adjunct therapy for recovery.

In a study of 36 subjects with persistent pain after lumbar surgery, pulsed electromagnetic field (PEMF) therapy with a 42-μs pulse width significantly reduced low-back pain by 40.2% compared to a sham treatment, indicating its potential effectiveness for postoperative pain relief.

The 42-μs PEMF therapy also showed a notable reduction in leg pain by 45.0%, suggesting that this treatment may help alleviate both low-back and radiating leg pain following lumbar surgery.

In a study involving 16 healthy dogs undergoing ovariohysterectomy, pulsed electromagnetic field (PEMF) therapy showed potential to reduce post-operative pain when combined with morphine, as indicated by lower pain scores in the magnet/morphine group compared to the control group.

While the results did not show a clear overall benefit of PEMF alone, the findings suggest that PEMF may enhance the effectiveness of morphine analgesia, warranting further investigation into its analgesic properties.

Pulsed electromagnetic field (PEMF) therapy has been shown to effectively manage postsurgical pain and edema, as well as promote healing in chronic wounds, making it a valuable tool in plastic surgery.

PEMF therapy is noninvasive and has no known side effects, providing a safe adjunctive treatment option for postoperative recovery, supported by scientific evidence of its mechanism of action.

In a double-blinded, randomized trial involving 118 post-appendicectomy patients, pulsed electromagnetic field (PEMF) therapy did not significantly reduce postoperative pain or the use of intravenous fentanyl compared to a placebo device over the first 12 hours after surgery.

Both pain scores and fentanyl usage declined similarly in both the active-PEMF and inactive control groups, indicating that PEMF is not an effective adjunct for pain management in this surgical context.
