The diagnosis of somatic dysfunction is supported by the recording of positive musculoskeletal findings (altered structure, motion, tissue). We conducted a national survey to assess the status of the documentation of this relationship in the hospital setting. The 26 participating osteopathic training hospitals submitted 719 admitting physical examination(More)
Parts I and II of this study compared kinematic and myoelectric data for two groups of asymptomatic subjects classified as having symmetric or asymmetric motor response to a palpatory test for cervical sidebending. Kinematic data revealed that asymmetric subjects had limited mobility for primary and secondary motions. Myoelectric activity was slow to be(More)
The present study examined organizational patterns of individual muscular contributions to head and neck motion. Previous studies of asymptomatic subjects with cervical motor asymmetry identified significant kinematic and myoelectric alterations. The current study evaluated 34 asymptomatic subjects categorized as to symmetry group based on initial palpatory(More)
Osteopathic physicians may use regional diagnostic rotation tests of the spine during physical examinations for patient evaluations. Clinical judgments of these responses relate to symmetry as a criterion for mobility. This first part of a two-part study reports the authors' investigation of regional ipsilateral myoelectric activity during responses to(More)
