The Science of Healing with Light: Understanding MLS Laser Therapy

As a practitioner constantly seeking the most effective, non-invasive solutions for my patients, I’ve been deeply impressed by the capabilities of Multiwave Locked System (MLS) Laser Therapy. This isn’t just another modality; it’s a sophisticated therapeutic tool that harnesses the power of light to stimulate the body’s natural healing processes. The technology is based on photobiomodulation, in which specific wavelengths of light are absorbed by photoreceptors in our cells, triggering a cascade of beneficial biochemical events.

What sets MLS apart is its patented combination of two synchronized wavelengths:

• 808-nanometer (nm) continuous-wave laser: This wavelength is primarily anti-inflammatory and anti-edemic. It works by enhancing blood circulation and lymphatic drainage, which helps reduce swelling and removes metabolic waste products from the injured area.
• 905 nanometers (nm) super-pulsed laser: This wavelength provides a powerful analgesic (pain-relieving) effect. Its high peak power, delivered in extremely short pulses (nanoseconds), can penetrate deep into tissues to directly impact nerve cells, reducing their excitability and blocking the transmission of pain signals to the brain.

The “locked” system ensures these two wavelengths are delivered simultaneously. The 905 nm pulse delivers a strong, deep-reaching therapeutic punch, while the 808 nm continuous-wave maintains the anti-inflammatory and healing response. This synchronized delivery allows for a high dose of energy to reach the target tissue without generating excessive heat at the skin’s surface. This is a crucial safety feature that prevents thermal damage and makes the treatment comfortable for the patient. In my clinical observations, patients rarely feel more than a gentle, soothing warmth, if anything at all.

A Clinical Demonstration: Treating Low Back Pain with the M6 Robotic Laser

To bring this science to life, let’s walk through a typical treatment scenario in my clinic. Recently, we had a patient, John, who presented with classic symptoms of facet joint irritation at the L4-L5 level, characterized by localized pain, stiffness, and some radicular discomfort down his right side.

Patient Setup and Comfort

The first priority is always patient comfort. For low back treatments using the robotic M6 laser, the patient lies face down on the treatment table. It is essential that the laser is applied directly to the skin for optimal energy absorption, so we make sure the area is properly exposed. If a patient is unable to lie still or is in extreme pain, this robotic setup provides a consistent, hands-off application, which is a significant advantage.

Targeting the Treatment Area

The M6 robotic laser features a sophisticated interface that allows for precise targeting. The process is straightforward:

1. Select the Condition: We choose the pre-programmed protocol for “Joint Pain and Stiffness” in the lumbar region.
2. Center the Target: I zero out the X and Y axes of the robotic head and position the aiming beam directly over the primary site of John’s pain—in this case, the L4-L5 facet joints, with a slight bias to the right.
3. Expand the Treatment Zone: This is where the clinical multimodal approach comes in. Instead of just treating the “spot of pain,” I expand the treatment area using the X and Y controls. This allows the laser to cover not only the specific vertebral level but also the surrounding connective tissues, including the multifidus muscles, ligaments, and fascia. This global approach addresses the entire dysfunctional kinetic chain, not just the epicenter of the symptom. The goal is to treat the source while also supporting the surrounding tissues that have been compensating for the injury.

Calibrating the Dose: Energy Density vs. Total Joules

A common point of confusion in laser therapy is the concept of dosage. While many lasers are marketed by “total joules” delivered, the more clinically relevant metric is energy density, measured in joules per square centimeter (J/cm²). This represents the amount of energy delivered to a specific area of tissue.

Leading research, supported by organizations like the World Association for Laser Therapy (WALT), indicates that the optimal therapeutic window for most musculoskeletal conditions is between 4 and 10 J/cm².

• For John’s condition, the protocol is set to deliver 6 J/cm². The M6 software automatically calculates the required treatment time (in this case, eight minutes) to deliver this precise energy density over the selected area. If I were to change the size of the treatment area, the software would instantly recalibrate the time to maintain that target density—a significant technological advancement that ensures treatment consistency and efficacy.

During the session, it’s fascinating to use a smartphone camera to visualize the treatment field. While the red aiming light is visible, the camera’s sensor can detect the 808 nm infrared wavelength, revealing a large triangular area of tissue being treated at any given moment by the robotic head. This visual confirmation helps patients and clinicians understand the laser’s extensive coverage.

The Dual-Modality Approach: Combining Robotic and Handheld Lasers

The MLS system offers incredible versatility by allowing the use of the M6 robotic laser in conjunction with a handheld applicator. These operate on two separate channels, enabling a dynamic, multi-pronged treatment within a single session.

While the M6 robot was treating the broader lumbar region, I used the handheld applicator to target specific trigger points I identified in John’s paraspinal muscles and quadratus lumborum. These “knots” are hyperirritable spots in the muscle tissue that contribute to the overall pain pattern. One of my mentors, a Doctor of Physical Therapy, once used the analogy of feeling for “cooked meat” (the tight, knotted tissue) versus “raw meat” (the soft, pliable tissue). The handheld laser allows me to deliver a focused dose of energy directly to these trigger points, helping release tension and improve muscle function. This combined approach is highly efficient; the robot provides a broad, systemic effect, while the handpiece offers a focused, targeted intervention.

Integrating MLS Laser with Chiropractic and Functional Medicine

MLS Laser Therapy is not a standalone cure; it is a powerful catalyst within a comprehensive, integrative treatment plan. At our clinic, it functions as a key component of a patient’s journey back to health.

Synergy with Chiropractic Care

As a chiropractor, my primary goal is to restore proper biomechanics and nervous system function through spinal adjustments. However, when a patient presents with significant inflammation and muscle guarding, performing an adjustment can be difficult and uncomfortable.

• This is where MLS laser therapy shines. By applying the laser before an adjustment, we can significantly reduce pain and inflammation. The muscles become more relaxed, and the patient’s pain threshold is increased. This “preps” the area, allowing me to perform a more effective and gentle adjustment. The adjustment restores joint mobility, and the laser therapy accelerates the healing of the associated soft tissues. This creates a powerful positive feedback loop in which each modality enhances the effect of the other.

Role in Functional Medicine and Metabolic Optimization

From a functional medicine perspective, chronic pain and inflammation are often linked to underlying systemic issues, including mitochondrial dysfunction. Mitochondria are the powerhouses of our cells, responsible for producing ATP (adenosine triphosphate), the body’s energy currency. Many chronic diseases and even certain medications, like statins, can impair mitochondrial function, leading to a cellular energy crisis that perpetuates inflammation and hinders healing.

Photobiomodulation directly targets the mitochondria. A key photoreceptor in this process is cytochrome c oxidase, an enzyme in the mitochondrial respiratory chain. When laser energy is absorbed by this enzyme, it boosts its activity, leading to:

• Increased ATP production: More cellular energy is available for repair and regeneration.
• Modulation of Reactive Oxygen Species (ROS): While high levels of ROS cause oxidative stress, low levels act as important signaling molecules that activate healing pathways.
• Activation of Transcription Factors: This leads to the synthesis of proteins involved in cell proliferation, inflammation reduction, and tissue repair.

This raises an exciting question: can we further optimize these mitochondrial effects? This is where functional medicine principles become critical. By addressing a patient’s diet, nutrient deficiencies, and exposure to metabolic toxins, we can enhance their cellular health. For example, supplementing with CoQ10, PQQ, L-carnitine, or NAD+ precursors could theoretically improve mitochondrial density and function, potentially making the cells more responsive to laser therapy. This represents the next frontier of personalized, integrative medicine—combining external energy-based therapies with internal biochemical optimization.

Advanced Protocols: MLS Laser and Orthobiologics (PRP)

One of the most exciting applications of MLS laser therapy is its use in conjunction with orthobiologic treatments like Platelet-Rich Plasma (PRP) injections. PRP therapy involves concentrating a patient’s own platelets and injecting them into an injured area to stimulate healing. However, the success of PRP depends heavily on the health of the surrounding tissue environment.

Research and advanced clinical protocols now suggest a multi-phase approach using MLS laser to augment PRP outcomes:

1. Priming Phase (Pre-Injection): We recommend two to three laser sessions in the week leading up to the PRP injection. The goal here is to “prepare the soil.” The laser reduces local inflammation, increases blood flow, 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 is performed on the same day as the PRP injection. This helps to further enhance circulation and can modulate the immediate post-injection inflammatory response. A common concern with PRP is the intense pro-inflammatory phase that occurs in the first week. While we don’t want to eliminate this crucial healing phase, MLS laser therapy appears to augment and modulate it, rather than suppress it. It helps manage the pain associated with this phase while supporting the platelet-initiated cellular signaling cascade.
3. Regenerative Phase (Post-Injection): A series of six or more laser sessions is performed in the weeks following the injection. The laser continues to provide the cells with the energy (ATP) needed to carry out the regenerative processes stimulated by the PRP, leading to more robust and organized tissue repair.

Clinical evidence suggests that this combined protocol can improve outcomes by 15-20% compared to PRP alone. It’s a prime example of how combining technologies can create a synergistic effect that is greater than the sum of its parts.

Treatment Frequency and Duration: Setting Patient Expectations

Properly setting patient expectations is crucial for compliance and success. A condition that developed over years will not resolve in a single 10-minute session. The effects of MLS laser therapy are cumulative.

• Acute Conditions: For recent injuries, a typical protocol consists of 6 treatments.
• Chronic Conditions: For long-standing issues, 12 or more treatments are often necessary.

Ideally, treatments are scheduled two to three times per week (e.g., Monday, Wednesday, Friday) to allow at least 24 hours between sessions for the biological effects to unfold. It is vital that patients complete the full recommended course. Many will start to feel significant improvement after just three or four sessions and may be tempted to stop. However, completing the full protocol is essential to ensure that the cellular and tissue-level changes are fully established, leading to lasting results. Once the initial protocol is complete, some patients with chronic conditions like osteoarthritis benefit from a maintenance program, with sessions every few weeks or months to keep pain and inflammation at bay.

The journey to healing is a partnership between the clinician and the patient. By leveraging advanced technologies such as MLS Laser Therapy within a comprehensive, integrated framework that includes chiropractic care, medical oversight, and functional medicine, we can empower the body’s innate healing intelligence and guide our patients toward a life of optimal health and vitality.
