Class IV MLS
Laser Therapy
Class IV MLS Laser Therapy in Fort Lauderdale is a non-invasive treatment option designed to deliver therapeutic light energy to painful or injured tissues. At IROSM, this technology may be used as part of a comprehensive plan for chronic pain, arthritis, tendon pain, muscle injury, inflammation, and musculoskeletal recovery.
MLS stands for Multiwave Locked System. This technology uses synchronized laser wavelengths to help support pain reduction, inflammation control, circulation, and tissue-repair pathways in appropriately selected patients.

Class IV MLS Laser Therapy is a form of therapeutic laser treatment that uses light energy to interact with tissues. MLS stands for Multiwave Locked System, a technology that uses synchronized laser emissions to target pain, inflammation, and tissue-repair pathways.
In musculoskeletal medicine, laser therapy is often discussed under the broader category of photobiomodulation. The goal is to use specific light energy to influence cellular activity, circulation, inflammation, and pain signaling in a controlled, non-invasive way.
Unlike medications or injections, MLS laser therapy does not require a needle, incision, anesthesia, or downtime for most patients.
How MLS Laser Therapy May Help
Therapeutic laser treatment is designed to deliver light energy into targeted tissues. In appropriately selected patients, this may help support pain relief, reduce inflammation, improve local circulation, and assist the body’s natural recovery process.
Pain Relief
MLS laser therapy may help decrease pain signaling and improve comfort in patients with certain chronic or acute musculoskeletal conditions.
Inflammation Support
Laser therapy is often used to help calm inflammatory tissue responses that contribute to pain, swelling, stiffness, and limited function.
Soft Tissue Recovery
MLS laser therapy may be used as an adjunct for tendon, ligament, muscle, and soft tissue recovery when appropriate.
Non-Invasive Treatment
Treatment is performed externally over the painful area. There is no injection, incision, or surgical recovery period.
Conditions That May Be Evaluated for MLS Laser Therapy
MLS laser therapy may be considered as part of a treatment plan for patients with pain, inflammation, stiffness, or soft tissue irritation. It is not a cure-all, and candidacy depends on diagnosis, severity, medical history, and treatment goals.
Common areas and conditions patients ask about include:
- Chronic low back pain
- Neck pain
- Knee arthritis and joint pain
- Shoulder pain
- Rotator cuff tendinopathy
- Tennis elbow and golfer’s elbow
- Achilles tendon pain
- Plantar fasciitis
- Hip bursitis and lateral hip pain
- Muscle strains
- Ligament sprains
- Post-injury soft tissue pain
- Post-procedure inflammation and recovery support, when appropriate
What Makes MLS Laser Different?
MLS laser therapy is designed to use synchronized wavelengths rather than a single light emission pattern. This is intended to combine analgesic and anti-inflammatory effects while delivering therapeutic energy to targeted tissues.
In practice, this means the treatment can be customized based on the painful area, tissue depth, patient tolerance, and treatment goals. Protocols may vary depending on whether the goal is pain reduction, inflammation control, tissue recovery, or support during rehabilitation.
What to Expect During Treatment
1. Evaluation First
Your visit begins with an orthopedic or pain-management evaluation. We review your symptoms, diagnosis, imaging when available, prior treatments, and goals.
2. Treatment Planning
If MLS laser therapy is appropriate, a treatment plan is created based on the painful area and condition being treated. Some patients may need a series of sessions rather than a single treatment.
3. Laser Session
During treatment, the laser applicator is placed over or moved across the targeted area. Protective eyewear is used. Most sessions are comfortable and do not require anesthesia.
4. Follow-Up and Integration
MLS laser therapy is often paired with rehabilitation, activity modification, strength work, regenerative options, injections, or other orthopedic treatments depending on the diagnosis.
How Many Treatments Are Needed?
The number of sessions depends on the condition, chronicity, severity, and patient response. Acute injuries may require fewer sessions, while chronic pain or degenerative conditions often require a series of treatments.
Some patients feel improvement early, while others respond gradually over multiple sessions. The treatment plan should be individualized and adjusted based on progress.
Is MLS Laser Therapy Safe?
MLS laser therapy is generally considered non-invasive and well tolerated when performed with appropriate protocols and safety precautions. Protective eyewear is required because therapeutic lasers can be harmful to the eyes.
Laser therapy may not be appropriate over certain areas or in certain patients, including some patients with active malignancy in the treatment area, pregnancy over certain areas, specific photosensitivity conditions, or other medical considerations. A proper evaluation is needed before treatment.
MLS Laser Therapy vs. Medications, Injections, or Surgery
MLS laser therapy is not the same as a steroid injection, PRP injection, nerve block, radiofrequency ablation, or surgery. It is a non-invasive modality that may help reduce pain and support recovery, but it does not structurally repair every injury or reverse advanced arthritis.
For many patients, laser therapy is best used as part of a broader plan that may include diagnosis-specific rehabilitation, image-guided procedures, regenerative medicine, bracing, nutrition, weight management, and activity modification.
Research & Evidence Summary
Research on therapeutic laser treatment and photobiomodulation is growing. Systematic reviews suggest that high-intensity laser therapy may help improve pain and function in some musculoskeletal disorders, although study quality, treatment protocols, and patient populations vary.
MLS-specific studies in low back pain and neck pain are emerging. Some studies show pain reduction and functional improvement, while others show improvement in both active and sham groups, meaning that results should be interpreted carefully.
- High-intensity laser therapy: Reviews suggest potential benefits for pain, function, range of motion, and quality of life in musculoskeletal disorders, but conclusions should be cautious because of study heterogeneity and risk of bias.
- MLS laser therapy: MLS has been studied in chronic low back pain and chronic neck pain, with some evidence suggesting pain reduction, though further high-quality trials are needed.
- Photobiomodulation: Broader photobiomodulation research supports possible effects on pain and inflammation, but protocols vary widely by wavelength, dose, condition, and treatment schedule.
