Center for Orofacial Pain Research

"Richard Ohrbach".

This group focuses on research questions that revolve around pain, function, diagnosis and classification. The research activities take place within three laboratories for primary data collection: neurosensory, biomechanics and psychophysiology.

About The Center for Orofacial Pain Research

In addition to our laboratories, we also utilize a clinic setting for some of our studies. We partner with multiple institutions in the U.S., as well as internationally, for larger scale projects. The spectrum of chronic pain in general is an overarching perspective for our research activities that include determinants of motor behavior and its peripheral organization, diagnostic methods, disability and the biopsychosocial model of disease, instrument development, international studies, joint mechanics, longitudinal studies and taxonomic development. We are active members of the International RDC/TMD Consortium Network.
