Cold laser therapy, also called low-level laser therapy (LLLT) or photobiomodulation, uses specific wavelengths of red and near-infrared light to calm inflammation, ease pain, and support tissue healing without heat, needles, or medication. At Family Tree Chiropractic in Oklahoma City, we use it alongside chiropractic adjustments and shockwave therapy for conditions like back pain, neck pain, sciatica, and tendon injuries. Sessions are painless and quick, and most patients need a series of treatments for the best results.
Cold laser therapy is one of the more promising non-invasive options in chiropractic and rehabilitative care, offering a drug-free path to pain relief. Unlike surgical lasers that generate heat to cut tissue, cold lasers work at low intensities that reach into tissue without causing thermal damage, which makes them very safe for therapeutic use.
The growing popularity of cold laser therapy in Oklahoma City reflects a broader shift toward treatments that address the causes of pain rather than only masking symptoms. For patients with back pain, neck pain, and sciatica, it can be a valuable part of conservative care. This guide covers the science, the conditions it treats, what treatment feels like, and how it works with therapies like shockwave therapy.
How Cold Laser Therapy Works
The Science Behind Cold Laser Therapy
Cold laser therapy works through photobiomodulation, a process where specific wavelengths of light interact with cells to trigger helpful biological responses. When red and near-infrared light is applied to the body, the light passes through the skin and is absorbed by light-sensitive molecules in the cells.
The main target is cytochrome c oxidase, an enzyme in the mitochondria, the energy-producing parts of each cell. When it absorbs laser light, cellular energy production (ATP) increases. A lab study from researchers at Harvard and MIT found that in muscle cells exposed to red and near-infrared light, ATP production peaked 3 to 6 hours after treatment, giving cells more energy for repair.
Therapeutic wavelengths fall within what scientists call the “optical window,” a range where light can travel into tissue without being absorbed too quickly by water or blood. Red light (600 to 700 nm) is typically used for more superficial tissue, while near-infrared light (780 to 950 nm) reaches deeper into muscles, joints, tendons, and nerves.
Cellular Effects and the Healing Cascade
The energy absorbed by cells starts a chain of healing responses. A review in the Journal of Functional Morphology and Kinesiology describes how photobiomodulation influences cellular metabolism, the tissue environment, and inflammation while posing minimal risk.
Reduction of inflammation. Laser light is thought to lower pro-inflammatory signaling molecules such as interleukin-1 beta and tumor necrosis factor-alpha while supporting anti-inflammatory signals. This can help ease swelling and pain without the side effects of anti-inflammatory medications.
Better blood flow and oxygen delivery. Cold laser therapy promotes the widening of blood vessels, partly through the release of nitric oxide. More circulation brings oxygen and nutrients to damaged tissue and helps clear waste products from the injury site.
Collagen production. Collagen is the main structural protein in tendons, ligaments, cartilage, and skin. Cold laser therapy stimulates the cells that make collagen, which supports the repair of sprains, strains, and long-standing tendon problems.
What Cold Laser Therapy Does for Your Body
Pain Relief Mechanisms
Cold laser therapy eases pain through several connected mechanisms, which is why it can help both new injuries and chronic pain.
Calming irritated nerves. Laser therapy can reduce the excitability of pain-transmitting nerves, which helps quiet pain signals. Some patients notice relief during or soon after treatment.
Natural pain relief. Research suggests laser therapy may encourage the release of the body’s own pain-relieving chemicals, such as endorphins, without the dependency risks of opioid medications. For people managing headaches and migraines, that can be an appealing alternative to frequent medication.
Acute and chronic pain. For new injuries, cold laser therapy helps control the early inflammatory response while supporting repair. For chronic pain, it targets the ongoing inflammation and cellular dysfunction that keep discomfort going.
Anti-Inflammatory Benefits
Inflammation plays a central role in pain for nearly every musculoskeletal condition. Cold laser therapy’s effects can help reduce swelling, ease muscle spasms, and create a better environment for healing.
The therapy supports lymphatic drainage, which helps clear excess fluid from injured areas. Less swelling means less pressure on surrounding tissues and nerve endings, which often eases pain and stiffness.
Rather than simply shutting inflammation down, cold laser therapy appears to help it move through its natural healing process, which may reduce the chance of lingering, chronic inflammation.
Tissue Repair
Muscle, tendon, and ligament healing. Cold laser therapy supports the cells involved in tissue repair. For athletes and active people recovering from strains or tendon injuries, that can mean a smoother return to activity.
Cartilage support. Cartilage has limited ability to heal on its own. Cold laser therapy can help by calming inflammation in the surrounding tissue, which makes it a useful part of care plans for osteoarthritis.
Nerve recovery. Animal and lab research, including a review in the Journal of Lasers in Medical Sciences, suggests laser therapy may support the regeneration of injured peripheral nerves. That’s one reason it’s of interest for sciatica and other nerve-related pain, though more human research is needed.
Muscle Relaxation and Improved Mobility
Cold laser therapy can help relax muscle spasms and chronic tension by improving circulation and cellular function in the area.
Many patients report easier joint movement after treatment, as less inflammation and muscle tension allow more freedom of motion. For people with shoulder pain or other stiff joints, that can make daily life noticeably easier.
The Cold Laser Therapy Treatment Process
What to Expect During a Session
Setup. You’ll sit or lie comfortably with the treatment area exposed. Both you and your provider wear protective eyewear, a standard safety step with any laser device.
Application. Your provider uses a handheld laser device, about the size of a flashlight, held on or just above the skin over the treatment area. Sessions usually take 5 to 15 minutes, depending on the size of the area and the condition.
What it feels like. Most patients feel little or nothing, which is why it’s called a “cold” laser. Some notice mild tingling or gentle warmth as circulation increases. There’s no pain, vibration, or noise, and many patients find it relaxing.
Frequency and Duration of Treatments
Typical course. Most patients benefit from a series of treatments rather than a single session, often around 6 to 15 sessions depending on how severe and long-standing the problem is. Many patients notice improvement after 3 to 5 treatments, with full benefits building over several weeks.
Frequency. During the active phase, sessions are usually scheduled 2 to 4 times per week. This lets effects build while giving tissues time to respond. As you improve, visits taper to maintenance as needed.
Long-term results. Benefits can last beyond the treatment period. In a well-known analysis of laser therapy for chronic neck pain, pain relief was still measurable up to about 22 weeks after treatment ended.
Personalized Treatment Plans
At our Oklahoma City clinic, every plan is tailored to the patient.
Condition severity. Recent injuries may respond to a shorter course, while chronic conditions usually need a longer plan.
Treatment settings. Wavelength, power, and treatment time are adjusted based on the location and depth of the affected tissue.
Integration with other therapies. Cold laser therapy often works best as part of a broader plan that may include spinal adjustments, shockwave therapy, rehabilitative exercises, and lifestyle recommendations.
Conditions Commonly Treated with Cold Laser Therapy
Musculoskeletal Injuries and Pain
Back pain. Chronic and acute back pain often responds to cold laser therapy, especially when muscle strain, ligament injury, or inflammation is involved. The American College of Physicians included low-level laser therapy among its non-drug options for chronic low back pain, though it rated the supporting evidence as low quality.
Neck pain. Research has shown cold laser therapy can help neck pain, with benefits lasting around 20 weeks in some studies. It can be a useful option for chronic neck tension, muscle strain, and some disc-related neck pain.
Arthritis. People with osteoarthritis and rheumatoid arthritis may benefit from cold laser therapy’s pain-relieving and anti-inflammatory effects, which can ease joint pain and stiffness.
Tendinitis and soft tissue injuries. Tennis elbow, golfer’s elbow, rotator cuff tendinitis, and Achilles tendinopathy can respond well, since the therapy supports collagen production and calms inflammation.
Sprains and strains. Acute ligament sprains and muscle strains benefit from better inflammation control and repair. Athletes often add laser therapy to their recovery routines.
Nerve Pain and Neuropathy
Sciatica. Sciatic nerve pain often comes from nerve irritation caused by herniated discs, spinal stenosis, or muscle tension. Cold laser therapy may help by reducing inflammation around the nerve and easing pain, and many patients notice less radiating pain, numbness, and tingling.
Peripheral neuropathy. People with nerve damage from diabetes, injury, or other causes may notice less numbness, tingling, or burning with cold laser therapy, though results vary and the research is still developing.
Carpal tunnel syndrome. The anti-inflammatory effects of cold laser therapy can help reduce swelling in the carpal tunnel and ease pressure on the median nerve.
Chronic Pain Management
For people living with persistent pain, cold laser therapy offers a non-addictive, drug-free option, which matters as healthcare works to reduce reliance on opioid medications. Some patients are able to cut back on pain medications as their symptoms improve.
Quality of life. Beyond pain relief, many patients report better sleep, mood, energy, and ability to get back to work and activities that pain had limited.
Benefits of Combining Cold Laser Therapy with Chiropractic Care
Better Outcomes When Used Together
Complementary effects. Chiropractic adjustments restore spinal motion, ease pressure on nerves, and improve how the musculoskeletal system works. Cold laser therapy adds inflammation control and tissue support. Adjustments can improve blood flow and nerve function in the area, while laser therapy can help maintain the benefits of adjustments by calming the inflammation that might pull tissues back into old patterns.
A comprehensive approach. At our Oklahoma City clinic, we often pair cold laser therapy with shockwave therapy for complex conditions. Cold laser therapy excels at calming inflammation and supporting cellular healing, while shockwave therapy targets scar tissue and chronic tendon problems. Together with adjustments, they address a problem from several angles.
Case Examples
Chronic back pain. Patients with long-standing back pain often have a mix of spinal restriction, muscle tension, and chronic inflammation. A plan combining spinal adjustments, cold laser therapy, and targeted strengthening exercises can bring real improvement to patients who have struggled for years.
Whiplash and accident injuries. Whiplash injuries from auto accidents often involve muscles, ligaments, discs, and nerves, along with significant inflammation. Cold laser therapy can be a strong complement to chiropractic care for accident recovery, especially when started early.
Migraine and headache management. People with chronic headaches and migraines often have neck tension, cervical restriction, or TMJ problems. Addressing these with chiropractic care while using cold laser therapy to calm inflammation can bring lasting relief for many patients.
Safety, Side Effects, and Contraindications
Is Cold Laser Therapy Safe?
Cold laser therapy has an excellent safety record when provided by trained professionals using FDA-cleared devices. It has been used in clinical settings for decades.
Non-invasive. There are no incisions, anesthesia, or recovery time, and you can return to normal activities right after a session.
Minimal side effects. Serious side effects are not expected with proper use. Mild, temporary effects can include warmth or tingling, slight redness, and, rarely, minor soreness.
No medication interactions. Because it works physically rather than chemically, cold laser therapy doesn’t interact with medications.
FDA clearance. Several cold laser devices are FDA-cleared for uses such as neck and shoulder pain, low back pain, and plantar fasciitis. Clearance means a device met the FDA’s safety and equivalence requirements for those uses.
Who Should Avoid Cold Laser Therapy?
Pregnancy. Cold laser therapy is not recommended during pregnancy, especially over the abdomen or lower back, because its effects on a developing baby haven’t been studied enough.
Cancer and suspicious lesions. The laser should not be used over known cancer, carcinomas, or suspicious moles. There’s no evidence it promotes cancer growth, but caution is warranted because of its effects on cell activity.
Eye exposure. Direct laser exposure can damage the retina, so protective eyewear is always required, especially when treating near the face or head.
Thyroid gland. The laser should not be applied directly over the thyroid.
Other considerations. Tell your provider if you have a pacemaker, cochlear implant, or other implanted device, or if you take immune-suppressing medications.
We review your health history before treatment to identify any reasons cold laser therapy may not be right for you. New numbness, weakness, or changes in bladder or bowel control need a medical evaluation first.
Preparing for Cold Laser Therapy
Patient Tips for Best Results
- Hydration. Staying well hydrated supports healthy tissue and helps you feel your best.
- Clean skin. Skip lotions, creams, or oils on the treatment area, since they can block light.
- Comfortable clothing. Wear loose clothing that allows easy access to the area being treated.
- Communication. Let your provider know about any changes in your condition or new symptoms between sessions.
- Follow instructions. Your provider may give specific instructions based on your condition.
Post-Treatment Care Recommendations
- Activity. Most patients can return to normal activities right away, though acute injuries may call for modified activity.
- Hydration. Keep drinking water after treatment to support your body’s healing.
- Monitor your response. Many patients notice gradual improvement between sessions. Report anything unexpected to your provider.
- Follow-up care. Keep up with adjustments, shockwave therapy if recommended, and home exercises.
- Consistency. Benefits build with each treatment, so sticking to your schedule matters.
