Effectiveness of the Michigan splint in reducing functional cervical disturbances: a preliminary study.

There is controversial evidence for a functional link between the masticatory apparatus and the cervical spine. The aim of this work was to perform a preliminary study to evaluate the effectiveness of the Michigan splint for the treatment of functional cervical disturbances. Forty patients with functional cervical disturbances were randomly organized into test and control groups. The patients in each group were examined by a physiologist to ascertain the extent of functional changes. The test group underwent splint therapy (Michigan type) during a two-month period. The other patients were sent home and did not receive active treatment. After two months, all patients were reassessed physiologically. Cervical pain and pain induced by epispinal or paraspinal pressure were reduced to a statistically significant extent in the treated group, compared with those in the control group.
