title: Craniomandibular stiffness in myogenous and arthrogenous CMD patients, and control subjects: a clinical and experimental investigation.
abstract: The purpose of this study was to compare active maximum mouth opening, endfeel distance, and craniomandibular stiffness values of three craniomandibular disorder (CMD) patient subgroups and a control group. The CMD patient subgroups consisted of myogenous pain patients and arthrogenous pain patients with a 'closed lock' and arthrogenous pain patients without a 'closed lock'. Both myogenous pain patients and the 'closed lock' patients showed great differences on all parameters (P < 0.05-P < 0.001). However, the arthrogenous pain patients without a 'closed lock' revealed no statistical differences with the control group on any of the tested parameters.
