Class 4 Summus Laser therapy uses high-powered therapeutic laser energy, a process known as photobiomodulation, to stimulate cellular healing, reduce inflammation, and support tissue repair. The laser energy penetrates deeply into the tissue, triggering a cellular response that increases blood circulation, promotes collagen production, reduces oxidative stress, and supports the body’s natural healing mechanisms. Unlike lower-powered cold laser devices, a Class 4 laser delivers enough energy to produce clinically meaningful results in a shorter treatment time. At Pro-Action in Kanata, our Summus Medical Laser is used alongside manual therapy and other modalities for pain relief, inflammation reduction, and recovery support.
