When you’re dealing with persistent pain, inflammation, or slow-healing injuries, you want treatments that work at the cellular level to accelerate your body’s natural healing processes. Deep tissue laser therapy—also known as high-intensity laser therapy or photobiomodulation—delivers therapeutic light energy deep into tissues, stimulating cellular repair and reducing pain and inflammation.
At Midas Physiotherapy in Oakville, we use Class IV therapeutic lasers capable of delivering sufficient energy to reach deep structures—muscles, tendons, ligaments, and joints that lower-powered devices cannot effectively treat. Unlike Class III “cold lasers” that work primarily on superficial tissues, our deep tissue laser therapy can target the source of your pain, not just the surface.
Whether you’re recovering from an acute injury, managing chronic pain, dealing with arthritis, or trying to heal a stubborn tendinopathy, deep tissue laser therapy may help accelerate your recovery. As part of our integrated approach, we combine laser therapy with hands-on treatment and exercise rehabilitation—because the best outcomes come from comprehensive care, not single modalities in isolation.
For Oakville residents seeking advanced pain relief and tissue healing, our Cornwall Road clinic offers deep tissue laser therapy as part of evidence-based physiotherapy care.
What Is Deep Tissue Laser Therapy?
Deep tissue laser therapy (also called high-intensity laser therapy, Class IV laser therapy, or therapeutic photobiomodulation) is a treatment that uses focused light energy to stimulate healing and reduce pain. The term “photobiomodulation” describes what actually happens: photo (light) + bio (living tissue) + modulation (change)—light energy creating beneficial changes in living tissue.
Unlike surgical lasers that cut tissue or cosmetic lasers that ablate skin, therapeutic lasers deliver energy that is absorbed by cells and converted into cellular activity—primarily increased ATP (energy) production and enhanced cellular metabolism. The result is accelerated tissue repair, reduced inflammation, and pain relief.

What to Expect During Treatment
Before Treatment
- Assessment: We evaluate your condition to determine if laser therapy is appropriate and to identify treatment parameters
- Screening: We screen for contraindications to ensure laser therapy is safe for you
- Skin preparation: The treatment area should be clean and free of lotions or oils
- Eye protection: Both you and the therapist wear protective eyewear during treatment
During Treatment
- Positioning: You’ll be positioned comfortably with the treatment area exposed
- Application: The laser handpiece is moved over the treatment area, either in contact with the skin or held slightly above it
- Sensation: You’ll typically feel a gentle, soothing warmth—this is normal and indicates energy is being delivered to the tissues
- Duration: Treatment typically takes 5–15 minutes depending on the area being treated and the condition
- Pain-free: Treatment should not be painful; inform your therapist if you feel any discomfort
After Treatment
- Immediate effects: Many patients notice some pain relief immediately; others feel improvement over the following hours or days
- No downtime: You can return to normal activities immediately
- Temporary response: Some patients experience temporary mild soreness or warmth in the treated area
- Cumulative benefit: Effects typically build with successive treatments
Treatment Course
The number of treatments needed depends on your condition:
- Acute conditions: May respond in 4–6 treatments
- Chronic conditions: Often require 6–12 treatments
- Frequency: Typically 2–3 times per week initially, spacing out as improvement occurs
- Maintenance: Some chronic conditions benefit from periodic maintenance treatments
Evidence and Research
Laser therapy has been studied extensively, with varying levels of evidence depending on the condition being treated. The quality of research has improved significantly in recent years with better standardization of treatment parameters.
| Condition | Evidence Summary |
| Neck pain | Strong evidence for short-term pain relief when used with appropriate parameters |
| Tennis elbow | Good evidence for pain reduction and improved grip strength |
| Achilles tendinopathy | Moderate-to-good evidence, especially combined with exercise |
| Knee osteoarthritis | Moderate evidence for pain relief; benefits appear to increase with adequate dosing |
| Low back pain | Mixed evidence; may be beneficial as part of multimodal treatment |
| Carpal tunnel syndrome | Promising evidence for mild-to-moderate cases |
| Shoulder pain | Moderate evidence for rotator cuff disorders and adhesive capsulitis |
| Wound healing | Good evidence for accelerated healing of various wound types |
Note: Evidence strength depends heavily on treatment parameters (wavelength, power, dose). Studies using inadequate parameters often show poor results, while studies using therapeutic doses consistently show benefit.
Frequently Asked Questions
Does laser therapy hurt?
No. Deep tissue laser therapy should feel like a gentle, soothing warmth. Many patients find it relaxing. If you feel excessive heat or discomfort, inform your therapist immediately so parameters can be adjusted. The treatment is non-invasive and well-tolerated.
How is this different from laser pointers or cosmetic lasers?
Therapeutic lasers are specifically designed to deliver energy that stimulates tissue healing without damaging tissue. Laser pointers are extremely low power and have no therapeutic effect. Cosmetic/surgical lasers are designed to cut, ablate, or destroy tissue—the opposite of therapeutic lasers. Our Class IV therapeutic laser delivers energy at wavelengths and power levels optimized for healing.
How quickly will I notice results?
Many patients notice some improvement after the first treatment—often reduced pain and improved range of motion. However, the effects are cumulative, and optimal results typically require a course of treatments. Acute conditions often respond faster than chronic conditions. We’ll monitor your progress and adjust your treatment plan accordingly.
How many treatments will I need?
This depends on your condition. Acute injuries may respond in 4–6 treatments, while chronic conditions often require 8–15 treatments. Some patients with chronic conditions benefit from periodic maintenance sessions. We’ll assess your response and recommend an appropriate treatment plan.
Is laser therapy safe?
Yes, when applied by trained clinicians following proper protocols, laser therapy has an excellent safety record. The main safety concern is eye protection—both patient and therapist wear protective eyewear during treatment. We screen all patients for contraindications before treatment. Side effects are rare and typically minor (temporary warmth or mild soreness).
Can laser therapy be used with other treatments?
Absolutely. Laser therapy is most effective as part of a comprehensive treatment plan. We often combine it with manual therapy, exercise rehabilitation, and other modalities. The pain relief and improved tissue healing from laser therapy can enhance your ability to participate in active rehabilitation.
Why does my condition need so many treatments?
Laser therapy works by stimulating your body’s natural healing processes at the cellular level. Each treatment triggers a cascade of biological effects that continue after you leave. Multiple treatments allow these effects to build, creating cumulative improvement. Chronic conditions have developed over months or years—reversing that process takes multiple sessions.
I have a pacemaker—can I have laser therapy?
Generally yes. Unlike electrical modalities, laser therapy doesn’t interfere with pacemakers or other implanted electronic devices. However, we would avoid treating directly over the device. Inform us about any implanted devices before treatment so we can take appropriate precautions.
Can laser therapy help my arthritis?
Research supports laser therapy for osteoarthritis, particularly knee osteoarthritis. While it won’t reverse structural damage to the joint, it can reduce pain, decrease inflammation, and improve function. Many arthritis patients find laser therapy helps manage their symptoms and reduces reliance on pain medication.
Why do I have to wear protective eyewear?
The laser light we use for therapy can potentially cause eye damage if it enters the eye directly or by reflection. The protective eyewear blocks the specific wavelengths our laser produces, completely eliminating this risk. Both you and your therapist wear appropriate eyewear throughout every treatment—this is a standard safety protocol for all therapeutic laser use.
Is laser therapy covered by insurance?
Laser therapy is provided as part of physiotherapy treatment, which is covered by most extended health insurance plans. Your coverage depends on your specific plan’s physiotherapy benefits. We can provide receipts with appropriate billing codes for your insurance claims.
I’ve tried laser therapy before and it didn’t work. Why would it work now?
Treatment parameters matter enormously with laser therapy. Many devices, particularly older Class III (cold) lasers, simply cannot deliver adequate energy to deep tissues. Additionally, wavelength, power, dose, and treatment time all affect outcomes. Class IV lasers with appropriate parameters consistently show better results in research. If previous laser therapy didn’t help, it may have been due to insufficient dosing rather than a failure of laser therapy itself.
