“…In nine out of 14 included studies JPSE was assessed in participants with traumatic neck pain (Heikkil€ a and Wenngren, 1998;Kristjansson et al, 2003;Sterling et al, 2003;Treleaven et al, 2003;Armstrong et al, 2005;Feipel et al, 2006;Grip et al, 2007;Sjolander et al, 2008;Woodhouse and Vasseljen, 2008). Seven of those nine studies used the classification of the Quebec Task Force on Whiplash-Associated Disorders (WAD) (Spitzer et al, 1995;Rydevik et al, 2008).…”

Convex hull area (CHA) and mean angle (MA) have been proposed to describe the behaviour of the helical axis during joint kinematics. This study investigates the intra-and inter-session reliability of CHA and MA during active movements of the cervical spine. Twenty-seven healthy volunteers (19 women) aged 23±2.8 years participated. Each volunteer was tested on two sessions. All participants were instructed to perform the following active movements of the cervical spine: rotation, flexion/extension and lateral bending, each performed to full range and repeated ten consecutive times. Cervical movements were registered with an electromagnetic tracking system. For each participant, each movement and each session, range of motion (ROM), CHA and MA were extracted. ROM showed high intra-and inter-session reliability during all cervical spine movements using this method. Overall, the intra-and inter-session reliability of the helical axis parameters varied depending on the movement direction and ranged from fair to almost perfect. The intra-and inter-session reliability of CHA and MA were almost perfect during rotation whereas the intra-and inter-session reliability of CHA was substantial during lateral bending and intra-and inter-session reliability of MA ranged from fair to substantial during flexion/extension and lateral bending. This is the first study to evaluate the reliability of helical axis measures during active movements of the cervical spine. The results show that CHA and MA are promising descriptors of cervical kinematics which could be applied in future studies to evaluate neck function in patients with cervical spine disorders.

“…[70][71][72][73] Neck pain patients also demonstrate greater postural sway, 74 a characteristic shared by patients with low back pain. 75,76 Evidence suggests that pain affects the motor brain, reducing the map volume of muscles in the primary motor cortex and 'smudging' the muscle representation of different muscles in the cortex.…”

“…44,68 Acute pain increases sympathetic activity and blood pressure, and, although the effects of chronic pain are more complex, chronic pain is also associated with sympathetic drive and hypertension. 69 In the presence of pain, proprioception and motor control become impaired, [65][66][67][70][71][72][73][74][75][76] potentially leaving the segment and region more vulnerable to further injury. Back pain appears to produce a change in motor strategy to protect and unload the injured structure, inhibiting the activation of deep spinal muscles and increasing activation of superficial lumbar musculature.…”

Somatic dysfunction: An osteopathic conundrum

Somatic dysfunction is considered a central concept for the theory and practice of osteopathy, but its relevance to the modern profession is questionable due to its unclear pathophysiology and poor reliability of detection. This article will explore the factors that may produce clinical signs attributed to somatic dysfunction and discuss the plausibility of the concept. A conceptual model is presented for the clinical diagnostic cues attributed to intervertebral somatic dysfunction, where signs of dysfunction arise from tissue and neurological factors related by a cycle of tissue injury and nociceptive-driven functional changes. Finally, the relevance of the concept of somatic dysfunction to the modern osteopathic profession is discussed and recommendations for the osteopathic profession are made.
