Myofascial Trigger Point Diagnostic Criteria in the Dog

SUMMARY

Objectives: The human model of the myofascial trigger point [TrP] construct was used to develop a diagnostic and therapeutic approach to pain syndromes unresponsive to conventional medical or surgical therapy in the dog. The aim was to identify diagnostic criteria and treatment modalities applicable to canine myofascial pain. Trigger point diagnostic criteria used in the dog are briefly described in this report.

Methods: Trigger point diagnostic criteria used in humans were adapted for use in clinically affected animals. In the absence of a pain chart for dogs, compensatory antalgic behaviors in the form of abnormalities of posture, movement and function are predictive of TrP location. Passive range of motion examination and muscle palpation provide confirmation of the presence of a TrP.

Results: Overall, an excellent response to treatment has been obtained in more than 600 cases.

Conclusions: Human myofascial pain syndromes have proved to be a very good model for these syndromes as they occur in the dog.
