What is the purpose of this trial?

This trial aims to determine if a special brace with laser lights can reduce pain and inflammation after spinal fusion surgery. Researchers compare this laser diode brace to a regular brace without laser technology. Participants will assess pain levels, functional ability, and wound healing progress over a year. Individuals who underwent minimally invasive spinal surgery in the lower back and have experienced back pain for over three months might be suitable candidates. As an unphased trial, this study allows participants to contribute to innovative research that could enhance post-surgical recovery for future patients.

Will I have to stop taking my current medications?

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 this laser diode brace is safe for use after spinal fusion surgery?

Research shows that photobiomodulation, which uses low-level laser therapy, is generally safe and well-tolerated. Studies have found that this therapy can relieve pain without causing side effects. For instance, one study found it to be a non-invasive and drug-free way to ease both short-term and long-term pain. Another study reported that it significantly reduced pain in patients who had lower back surgery. Additionally, the FDA has approved devices using this technology for pain management, indicating confidence in its safety. Overall, current evidence supports photobiomodulation as a safe option for managing pain and inflammation after surgery. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the laser diode brace for lower back pain following spinal fusion because it uses photobiomodulation, a cutting-edge technique that harnesses light energy to promote healing and reduce pain. Unlike traditional treatments that often rely on medication or physical therapy, this method directly targets the affected area with light, potentially speeding up recovery and improving function without drugs. The brace's innovative design allows for consistent, long-term application, which could lead to sustained pain relief and improved quality of life for patients.

What evidence suggests that the laser diode brace is effective for reducing lower back pain after spinal fusion?

Research shows that laser light, known as photobiomodulation, can help reduce pain and swelling. Studies have found that high-intensity laser therapy significantly decreases the release of substance P, a chemical that causes pain. Other research has shown that low-level laser therapy greatly reduces pain and improves movement in patients. This treatment is non-invasive and drug-free, making it a safe option for managing both short-term and long-term pain. In this trial, participants will join different groups to evaluate the effectiveness of a laser diode brace in reducing pain and aiding healing after spinal surgeries. One group will receive a brace with electrical diodes, while another will receive a sham brace without electrical diodes. ^{1 2 4 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• Photobiomodulation

Trial Overview The study compares two types of braces: one with laser diodes that may reduce pain and inflammation, versus a sham (placebo) brace without active lasers. The effect on post-surgical wound healing will also be assessed.

How Is the Trial Designed?

Group I: Brace With Electrical Diodes Experimental Treatment 1 Intervention

The patient will be given a laser diode brace to wear for 1 year. At the defined time points following surgery (2, 4, 6, 8, 12, 24, 36 and 48 weeks), subjects will be asked to complete pain and ability-to-function questionnaires and submit scar/wound images to determine their status at each time interval.

Group II: Sham Brace Without Electrical Diodes Placebo Group 1 Intervention

The patient will be given a sham/placebo laser diode brace to wear for 1 year. At the defined time points following surgery (2, 4, 6, 8, 12, 24, 36 and 48 weeks), subjects will be asked to complete pain and ability-to-function questionnaires and submit scar/wound images to determine their status at each time interval.

Published Research Related to This Trial

Photobiomodulation therapy (PBMT) showed no clinically important benefits in reducing pain and disability compared to sham treatment in individuals with acute/subacute or chronic non-specific low back pain, based on a systematic review of 12 randomized controlled trials involving 1,046 participants.

While PBMT was found to reduce pain and disability more than ultrasound, the differences were not deemed clinically significant, and it was less effective than Tecar therapy, indicating that current evidence does not support PBMT as an effective treatment for non-specific low back pain.

Laser photobiostimulation is an effective rehabilitation technique for spinal pain, providing analgesic and anti-inflammatory effects while also promoting tissue regeneration without age limitations or side effects.

This therapy is particularly important for individuals whose spinal pain affects their ability to work and engage in daily activities, highlighting the need for effective pain management in rehabilitation.

In a study involving 10 patients with low back pain, those receiving photobiomodulation (PBM) therapy alongside physical therapy showed a significantly greater reduction in depression scores compared to those receiving physical therapy alone.

The improvement in depression was independent of changes in functional status, suggesting that PBM may have a direct antidepressant effect in patients with low back pain and concurrent depression.

Systemic photobiomodulation is a cost-effective treatment for chronic low back pain, with an average cost of R$ 25.30 per session based on a study involving 20 nursing professionals.

The treatment involves 10 sessions using a specific laser equipment, and the majority of costs are attributed to labor (66%), making it a financially viable option compared to other therapies.

In a randomized trial involving 61 patients with chronic low back pain, low level laser therapy combined with exercise showed significant long-term benefits, including a reduction in pain and improved lumbar range of motion compared to exercise alone.

At 12 weeks, the combination treatment resulted in a pain reduction of 1.8 cm, increased lumbar movement by 0.9 cm, and a decrease in disability by 9.4 points, indicating that laser therapy can enhance the effectiveness of exercise for managing chronic low back pain.

Low-level laser therapy (LLLT) showed statistically significant but clinically unimportant pain relief in some patients with non-specific low-back pain, based on a review of seven randomized controlled trials involving 168 participants.

While LLLT did not demonstrate superior effectiveness compared to exercise alone in reducing pain or disability, it was associated with a lower relapse rate at six months, and no side effects were reported, indicating a potential safety profile.

In a study of 100 patients with chronic low back pain, combining Ga-Al-As diode laser therapy (980 nm) with exercise significantly reduced pain more than exercise alone, with a notable average decrease in pain scores (3.96 vs. 2.23 on the visual analogue scale).

The treatment involved low-level laser therapy administered three times a week for three weeks, suggesting that this combination therapy could be an effective option in rehabilitation programs for managing nonspecific chronic low back pain.

In a study of 75 patients with chronic low back pain, low power laser therapy (Gallium-Arsenide) was found to significantly reduce pain and improve functional disability, as measured by various clinical assessments.

All treatment groups, including those receiving laser therapy combined with exercise, laser therapy alone, and exercise alone, showed improvements, indicating that low power laser therapy is an effective option for managing chronic low back pain.

Low-level laser therapy (LLLT) effectively reduces pain and promotes healing by using coherent light in the 600 to 1000 nm wavelength range, which triggers biochemical changes in cells and has been supported by numerous clinical and experimental studies.

LLLT has shown significant analgesic and anti-inflammatory effects, making it a promising complementary treatment option for managing symptoms in patients with osteoarthritis and chronic pain.
