Electro-Stimulators are a type-2 medical device and are regulated by Health Canada.
There are a wide variety of stimulators made with different manufacturing standards and configurations. Lower end units may not deliver the specified frequencies precisely, spike when increasing intensity or may channel jump during stimulation. Professional units eliminate these problems and are excellent investments for practitioners who want to offer this type of treatment.
