Laser Therapy in St. Catharines

Laser therapy, also known as low-level laser therapy (LLLT), cold laser therapy, or photobiomodulation, is a non-invasive, drug-free treatment that uses focused light of specific wavelengths to stimulate cellular activity. It penetrates tissues and energizes mitochondria, promoting natural healing processes deep at the cellular level. At ProActive, we use Theralase® Cool Laser Therapy to deliver this treatment.

Theralase® Cool Laser Therapy (CLT) operates on this principle: it delivers billions of photons into tissue, where chromophores and cytochromes absorb them and convert light energy into chemical energy. This boosts tissue repair, reduces inflammation, and alleviates pain.

How does laser therapy work at ProActive?

How can laser therapy help me?

Laser therapy can help by reducing pain, decreasing inflammation, and speeding up your body’s natural healing process—all without the need for medication or invasive procedures. Using targeted light wavelengths, laser therapy stimulates your cells’ mitochondria, increasing energy production (ATP) and promoting tissue repair at the source of the problem. This process not only helps alleviate discomfort but also restores mobility and function, making it especially beneficial for conditions like arthritis, tendonitis, muscle strains, nerve injuries, and joint pain. Many patients experience relief within the first few sessions, and because it’s non-invasive, there’s little to no downtime, allowing you to return to your daily activities quickly.

In addition to pain relief, laser therapy can improve circulation, enhance cellular regeneration, and reduce scar tissue formation—making it a valuable tool for both acute injuries and chronic conditions. Whether you’re recovering from a sports injury, managing long-term joint pain, or seeking faster healing after surgery, laser therapy can provide targeted, evidence-based support for your recovery. At our Calgary clinic, treatments are tailored to your specific condition, ensuring the right wavelength, intensity, and duration for optimal results.
