MLS Laser Therapy Benefits for Inflammation and Recovery

MLS Laser Therapy Benefits for Pain and Inflammation

Abstract

Welcome to our educational series. I’m Dr. Alex Jimenez. In this post, we will explore the transformative world of Multiwave Locked System (MLS) Laser Therapy, a cutting-edge, FDA-cleared technology revolutionizing how we manage pain, inflammation, and tissue repair. We will journey through the fundamental principles of photobiomodulation, exploring how specific wavelengths of light—namely, the 808 nm continuous-wave and the 905 nm super-pulsed—work synergistically to stimulate cellular processes. This discussion will cover the therapy’s profound effects on mitochondrial function, leading to increased ATP production, its role in modulating the inflammatory cascade, and its ability to provide significant analgesia. We’ll examine the importance of “dosing” light energy, focusing on energy density (joules/cm²) rather than total joules, to achieve optimal therapeutic outcomes without risking bio-inhibition. Furthermore, we will explore integrating MLS Laser Therapy with other regenerative treatments, such as Platelet-Rich Plasma (PRP), and discuss how our multidisciplinary team at Injury Medical Clinic combines this advanced technology with comprehensive chiropractic, medical, and functional medicine protocols to create personalized, effective patient care plans.

A Multidisciplinary Vision for Patient-Centered Care

As a clinician with a passion for integrating diverse therapeutic modalities, I’ve always believed that the future of healthcare lies in a collaborative, patient-centered approach. At Injury Medical Clinic PA, this philosophy is the cornerstone of our practice. I am Dr. Alex Jimenez, and my credentials span chiropractic (DC), advanced practice nursing (APRN, FNP-BC), and functional medicine (CFMP, IFMCP, ATN, CCST). This diverse background allows me to view patient health through multiple lenses, from biomechanical integrity to cellular and metabolic function.

Our clinic’s strength is amplified by our multidisciplinary structure. We are proud to have Dr. Maria Guadalupe Cardenas, MD, as our Medical Director and Collaborative Physician. With over 40 years of experience as a board-certified internist, Dr. Cardenas provides invaluable medical oversight and clinical wisdom that enrich our patient care protocols. Her collaboration ensures that our treatments are not only innovative but also grounded in established medical principles, creating a safe and effective therapeutic environment.

This integrated model allows us to seamlessly combine integrative chiropractic care, medical diagnostics, functional medicine, personal injury rehabilitation, and cutting-edge technologies like MLS Laser Therapy. When a patient comes to us, they are not just seeing a chiropractor or a medical doctor; they are accessing a team dedicated to understanding the root cause of their condition and crafting a holistic treatment plan.

Understanding MLS Laser Therapy: A Clinical Demonstration

Today, I want to take you on a practical journey into one of the most exciting technologies in our clinic: Multiwave Locked System (MLS) Laser Therapy. Let’s walk through a typical session to understand how this technology works and why it’s so effective.

Imagine a patient, we’ll call him John, presenting with chronic low back pain and stiffness, specifically around the L4-L5 facet joints, with some sciatic-like pain radiating down his right side. Our first priority is always patient comfort. For low back treatment with our robotic laser head, we have the patient lie face down to ensure the treatment area is accessible, as the laser must be applied directly to the skin for optimal penetration.

• Setting Up the Treatment:
  • The MLS laser system features a sophisticated robotic arm that allows for precise, automated treatment of a defined area.
  • On the interface, I select the “Back” protocol and specify “Joint Pain and Stiffness.”
  • I zero out the X and Y axes on the control panel. This allows me to perfectly center the laser over the primary site of John’s discomfort—the L4-L5 region.
  • Once centered, I expand the treatment perimeter (the X and Y axes) to cover not just the “spot of pain” but the surrounding connective tissues. This is what we call our clinical multimodal approach—a global strategy that addresses both the symptom and the underlying dysfunctional biomechanical and fascial network.
• The Importance of Focal Distance:
  • The robotic laser head is designed to work at a specific distance from the skin to ensure the laser beams are perfectly focused. The system includes a small ruler to measure this distance, which is typically about six inches.
  • This precise focal point is crucial because the laser beam is collimated, meaning the light rays are parallel, ensuring the energy is delivered efficiently to the target tissue deep beneath the skin.
• Dual-Action Therapy:
  • While the robotic arm treats the broader lumbar region—an eight-minute protocol in this case—the MLS system enables concurrent treatment with a handheld applicator. This handpiece contains a single diode, whereas the robotic head has three.
  • The handpiece is ideal for targeting specific trigger points or “knots” in the muscle. I often use the analogy of “cooked meat vs. raw meat” to describe these points. Healthy, relaxed muscle feels like raw meat—pliable and soft. A trigger point feels like cooked meat—firm and knotted. The goal is to use the laser to help release these knots.
  • Using the handpiece, I can apply targeted energy to trigger points in the gluteal and piriformis muscles, which are often implicated in radiating leg pain. Each point is treated for just 25 seconds, making it a quick and efficient addition to the overall session.

This ability to use both the robotic arm for broad treatment and the handpiece for targeted therapy simultaneously is a significant advantage of the MLS system, allowing for a comprehensive and time-efficient session.

The Science of Light: How MLS Laser Creates a Healing Response

Patients often ask if they will feel anything during the treatment. The answer is typically no. Unlike high-power, continuous-wave lasers that generate significant heat, the MLS system uses patented synchronized-pulse technology. You might feel a gentle warmth or a slight tingling, but the treatment is overwhelmingly comfortable. This lack of sensation is due to the precise engineering of its dual wavelengths.

An interesting way to visualize this is to look at the treatment area through your phone’s camera. The human eye can see the red aiming beam, but the camera sensor can pick up the invisible therapeutic light. You’ll see a distinct triangle of light—this is the 808-nanometer wavelength at work. The 905-nanometer wavelength, because of its super-pulsed nature, is too fast for the camera to capture consistently.

• 808 nm Continuous Wave: This wavelength is excellent for its anti-inflammatory and anti-edema (swelling-reduction) effects. It penetrates tissue and is absorbed by chromophores (light-absorbing molecules) in cells, thereby modulating the inflammatory process. It promotes vasodilation, increasing blood flow to deliver more oxygen and nutrients to the area while removing metabolic waste.
• 905 nm Super-Pulsed Wave: This wavelength is delivered in extremely short, high-power bursts. Its primary effect is analgesic, or pain-relieving. It has a direct effect on nerve cells, slowing the transmission of pain signals to the brain and stimulating the release of endogenous opioids such as endorphins.
• The Synchronized Effect: The “secret sauce” of MLS is that these two wavelengths are delivered in a synchronized, locked pattern. The high peak power (50 watts) of the 905 nm pulse drives the light energy deep into the tissue, while the 808 nm wave sustains the therapeutic effect. The system then introduces a period of rest, allowing the tissue to absorb the energy fully without overheating. This is why the tissue temperature remains stable, indicating an efficient and safe energy transfer.

Energy Density: The Key to an Effective Dose

A common point of confusion in laser therapy is the concept of dosage. Many people focus on “total joules,” but the more clinically relevant metric is energy density, measured in joules per centimeter squared (J/cm²). Energy density represents the amount of energy delivered to a specific area of tissue.

Think of it like watering a plant. Simply dumping a gallon of water on it (total joules) isn’t effective if it all runs off. You need to apply the water at a rate the soil can absorb (energy density).

• The Therapeutic Window: Research, including guidelines from the World Association for Laser Therapy (WALT), suggests that the optimal therapeutic window for most musculoskeletal conditions is between 4 and 10 J/cm² (Hamblin, 2017).
• Avoiding Bio-inhibition: Delivering too little energy will have no effect, but delivering too much can be counterproductive. This is known as the Arndt-Schultz Law, which states that weak stimuli excite physiological activity, moderate stimuli favor it, strong stimuli inhibit it, and very strong stimuli destroy it. The MLS system’s pre-programmed protocols are designed to deliver optimal energy density while avoiding the risk of bio-inhibition, in which excessive energy can suppress cellular metabolism.
• Automatic Calibration: A key feature of the MLS M6 robot is its intelligent software. If I adjust the size of the treatment area (the X and Y coordinates), the machine automatically recalculates the treatment time to ensure it delivers the same target energy density. For John’s back pain, the protocol is set to deliver 6.8 J/cm², and the machine handles the rest.

Integrating MLS Laser with Regenerative Medicine

One of the most powerful applications of MLS Laser Therapy is its integration with orthobiologics, such as Platelet-Rich Plasma (PRP) injections. PRP therapy involves injecting a concentration of a patient’s own platelets to accelerate the healing of injured tendons, ligaments, muscles, and joints. The MLS laser serves as a powerful adjunctive therapy, enhancing PRP outcomes.

Here is the progressive protocol we often recommend:

1. Priming the Tissue (Pre-Injection): We recommend two to three laser sessions before the PRP injection. The goal is to “prepare the soil.” The laser reduces local inflammation, increases blood circulation, and begins to optimize the cellular environment, making the tissue more receptive to the growth factors introduced by the PRP.
2. Day of Injection: A laser session on the day of the injection can further enhance local blood flow and begin to modulate the intense inflammatory response that PRP is designed to initiate.
3. Enhancing the Healing Cascade (Post-Injection): We typically perform six laser sessions after the PRP injection. A common question is whether the laser’s anti-inflammatory effect will counteract PRP’s necessary pro-inflammatory phase. The answer is no. Photobiomodulation does not simply block inflammation; it modulates it. It helps guide the inflammatory process toward a more efficient, productive resolution phase, augmenting the platelets’ regenerative effects rather than suppressing them. Our clinical observations, supported by growing research, suggest that combining MLS with PRP can improve efficacy by an estimated 15–20% compared to PRP alone.

Optimizing Mitochondrial Function for Chronic Conditions

At the cellular level, the primary mechanism of MLS Laser Therapy is its effect on mitochondria, the powerhouses of our cells. The light energy is absorbed by an enzyme in the mitochondrial respiratory chain called cytochrome c oxidase. This absorption stimulates the mitochondria to produce more adenosine triphosphate (ATP), the universal energy currency of the cell.

This is where the conversation bridges from acute pain management to chronic disease and metabolic health—a core focus of functional medicine.

• The Cascade of Healing: When you treat a patient over a series of sessions (e.g., a chronic protocol of 12 treatments), the effects are cumulative.
  • Initial Sessions (1-3): The primary effect is analgesic. The laser calms irritated nerve fibers, providing immediate pain relief.
  • Middle Sessions (4-8): The anti-inflammatory and circulatory effects become more prominent. Swelling subsides, and the improved blood flow accelerates tissue repair.
  • Later Sessions (9-12): The sustained increase in ATP production kicks cellular metabolism into high gear. This enhanced energy supply allows cells to repair and regenerate more effectively, leading to long-term structural and functional improvements.
• A Functional Medicine Perspective: Many patients with chronic conditions are on medications like statins or metformin, which can negatively impact mitochondrial function. By using MLS laser, we are directly supporting mitochondrial health. This raises an exciting possibility: can we further optimize outcomes by combining laser therapy with targeted nutritional interventions?
  • Supplementing with mitochondrial cofactors like Coenzyme Q10 (CoQ10), PQQ (pyrroloquinoline quinone), NAD+ precursors, and creatine could theoretically amplify the benefits of laser therapy.
  • This represents the next frontier of integrative medicine—synergizing advanced technologies with personalized metabolic and nutritional strategies to create the most robust healing response possible.

At Injury Medical Clinic, this is the depth of care we strive to provide. We don’t just treat symptoms; we work to optimize the body’s innate healing intelligence from the cellular level up. By blending chiropractic care, advanced medical technology, and a deep understanding of functional biochemistry, we empower our patients to not just recover from injury but to achieve a new level of health and vitality.
