Pain Service

We provide expert pain management for newborns, infants, children and youth from across Canada. Our mission is to “Stop Pain Hurting.”

The Pain Service includes the Acute Pain Service and the Complex Pain Service. 

  • Acute pain is a protective mechanism that safeguards injured tissue from ongoing damage.
  • Complex pain is a dynamic phenomenon caused by numerous changes occurring in the peripheral and/or central nervous system. 

The changes of complex pain:

  • occur in response to disease, injury and/or loss of function;
  • are influenced by the nature, duration and original cause of the pain as well as the age, sex, psychological make-up and perhaps the genetic susceptibility of the child;
  • often result in abnormal activity in the pain messaging system that continues irrespective of the original cause;
  • are reversible initially, but without timely and appropriate management, the changes can persist.

myoActivation is a term trademarked by Dr Greg Siren (see Dr Lauder and Dr Siren have worked together to bring the benefits of myoAcitvation to children and youth referred to the BCCH Complex Pain Service. myoActivation is very different from simple dry needling of trigger points because it uses a structured assessment to target which muscles, fascia and scars that are important to minimize musle related pain. myoActivation is based on assesment of abnormal postural and subtle changes in muscle balance between right and left sides. It is important to know that the site of pain is often not the source of pain, for example, low back pain often comes from trigger points in the abdomen rather than the back. Immediate changes occur through a needling procedure in muscles and soft tissues like traumatic and surgical scars. There is usually more than one myoAcitvation session (2-4) to get to the treatment goal of reduced pain and improved flexibility.‎
