Intramuscular Stimulation (IMS) was developed by Dr Chan Gunn. Unlike other dry needling techniques, Gunn Intramuscular Stimulation is a total system for the diagnosis and treatment of neuropathic myofascial pain syndromes.
It can only be practised by doctors and physiotherapists who have been specially trained and certified by the Gunn IMS program. Training and certification are done at the University of British Columbia (UBC). This professional must possess a thoroughly tested and demonstrated knowledge of anatomy and no-go areas for dry needling.
