Animal care and use issues in movement disorder research

Animal models of movement disorders can present special challenges for the research institutions that use them. Such models often affect the animals' ability to ambulate and perform normal body functions, and these potential effects on health and well-being mandate additional steps to ensure humane animal care and use. Indeed, the appropriate level of care for these models may call for actions that go beyond what is required or considered standard for other protocols. A proactive team approach to animal use protocol development and animal management is important. Through the commitment and involvement of the entire team-researchers, facility personnel, and institutional animal care and use committee members--institutions that use these valuable models can ensure both the fulfillment of research objectives and the implementation of the best practices for animal care. Among the most commonly used animal models of movement disorder are models of stroke, brain and spinal cord injury, dystonia, Parkinson's disease, and Huntington's disease. Despite their relatively wide use, there is very little in the literature that describes the specific needs of individual models and the challenges those needs may present in today's regulatory environment. In this article, we discuss animal use considerations and provide the available animal care information on specific models.
