This practical, clinical manual presents a comprehensive system of diagnosis and treatment for chronic musculoskeletal pain based on Dr Gunn's own widely-acknowledged work.  Intramuscular stimulation (IMS) is a "dry needling" technique that uses a needle without injected medications to release muscle shortening which occurs in myofascial pain syndromes (i.e. chronic pain conditions in the musculoskeletal system when there is no obvious injury or inflammation).  With excellent illustrations to guide the practitioner, the information is applicable across a number of specialities, in particular, general and orthopedic practice, sports medicine, and manual and other physical therapies which seek a more effective physical modality for the management of chronic pain.
