Abstract
Osteopathic clinical examination is a multisensory experience that requires the integration of visual, tactile, and proprioceptive information regarding the assessment of tenderness, asymmetry, and the restriction of motion and tissue texture changes in the context of presenting symptoms and prior history. In this study, we investigated how osteopaths use their senses in the context of an osteopathic examination. Fifteen participants at different levels of expertise examined one subject with chronic back pain on two separate occasions. The osteopaths had to diagnose a somatic dysfunction in the spine and pelvis. All participants spent significantly more time using vision and touch simultaneously than vision or touch alone. Timecourse analysis revealed an obvious early emergence and subsequent prevalent simultaneous use of vision and touch observed for the expert clinicians. This contrasted with the behaviour displayed by the novices who at the beginning of their examinations seemed unable to focus on more than one sensory modality. The expert clinicians also demonstrated a higher degree of consistency in their diagnoses. These findings indicate that during the development of expertise in osteopathic practice, the integration of visuotactile information may become central to the diagnosis of somatic dysfunction thus contributing to increased diagnostic reliability.
