Documenting Pressures Used for Manual Diagnosis and Treatment of Cervical Spine Somatic Dysfunction

Background: Palpatory assessment of free or restricted motion patterns is part of the diagnosis of spinal somatic dysfunction (SD). Diagnostically, local soft tissues are compressed (pre-loaded) over the structure of interest followed by one or more test impulses to assess the quality of the “end-feel” motion in several planes. These barrier sensations are often described qualitatively but have not been objectively quantified. Noninvasive, tactile pressure sensors built into a digital palpation monitoring system (IsoTOUCH®; Neuromuscular Engineering; Nashville TN, USA) were used to document loading and impulse pressures for palpatory segmental diagnosis and to first engage and then quickly move through a restrictive SD barrier using an osteopathic manipulative treatment (OMT) technique
