“…This is supported by a report claiming that up to 80% of neck pain patients experience symptom aggravation with upper limb activity (Osborn and Jull, ), and studies showing reorganized muscle coordination (Helgadottir et al., ) and activity (Wegner et al., ; Zakharova‐Luneva et al., ; Castelein et al., ) during arm movements. Interestingly, subgroups differences in axioscapular muscle activity may exist in neck pain patients (Castelein et al., ). During an upper limb task, the upper trapezius muscle activity was reduced in patients with insidious onset of neck pain (IONP) but not in patients suffering from whiplash‐associated disorders (WAD) although they showed increased activity after completing the task (Falla et al., ).…”

“…found increased activity during isometric abduction and external rotation (Zakharova‐Luneva et al., ), while another study found decreased activity during a typing task (Wegner et al., ) even though both include IONP patients. These variable findings in different studies could be explained by the different tasks and patient populations investigated (Castelein et al., ). However, when considering all the studies and conflicting evidence on axioscapular muscle activity in neck pain patients (Castelein et al., ), there seems to be a wide ‘natural’ diversity, which could explain different findings in different cohorts.…”

“…The primary role of serratus anterior is to stabilise the scapula against the thorax and control scapular motion during movements of the shoulder (Lear and Gross, 1998;Smith et al, 2003;Castelein et al, 2015). Clinically, dysfunction of serratus anterior has been implicated in musculoskeletal disorders including shoulder and neck pain (Cools et al, 2014;Castelein et al, 2015).…”

“…Clinically, dysfunction of serratus anterior has been implicated in musculoskeletal disorders including shoulder and neck pain (Cools et al, 2014;Castelein et al, 2015). Thus in clinical practice the focus is to use exercisebased therapeutic interventions targeting serratus anterior in the rehabilitation of patients with shoulder or neck pain (Ebaugh et al, 2005;Witt et al, 2011;Holmgren et al, 2012;Worsley et al, 2013;Cools et al, 2014).…”

calculated. Three subdivisions of serratus anterior were identified. A new finding was the discovery of two distinctive fascicles attached to the superior and inferior aspects of rib 2.The rib 2 inferior fascicle had the largest PCSA (mean 1.6 cm 2 ) and attached, with the rib 3 fascicle, along the medial border of scapula to form the middle division. The rib 2 superior and rib 1 fascicles attached to the superior angle of scapula (upper division).Fascicles from ribs 4 to 8/9 attached to the inferior angle of scapula (lower division).Mean fascicle angle relative to a vertical midline reference and PCSA for each division were 29 o and 1.3 cm 2 (upper), 90 o and 2.2 cm 2 (middle), and 59 o and 3.0 cm 2 (lower).This novel study demonstrated the presence of morphologically distinct serratus anterior subdivisions. The results of this study will inform the development of optimal techniques for the assessment, treatment and rehabilitation of this architecturally complex muscle in shoulder and neck pain.

“…Johnson et al, (1994) describe the action of the LT in arm elevation as fixating the axis of rotation around the deltoid tubercle. Like the UT, there are mixed reports of alterations in activity levels of the LT in people with neck pain (Castelein et al, 2015;Castelein et al, 2016;Petersen et al, 2016;Petersen and Wyatt 2011;Wegner et al, 2010;Zakharova-Luneva et al, 2012).…”

Refining scapulothoracic kinematic measurement and characterising scapulothoracic resting posture in those with and without chronic non-specific neck pain

Neck pain is a common and recurrent condition affecting between 30 to 50% of adults in any given year. People experiencing neck pain commonly report difficulties in performing activities involving the upper extremity. Furthermore, clinical trials that have included exercises that target the shoulder girdle have shown beneficial effects in reducing neck pain. These observations are feasible based on the biomechanical dependence of the cervical spine and shoulder girdle, which includes common muscle attachments. However, to date there has been a paucity of studies investigating underlying movement disorders of the shoulder girdle in people with neck pain. This is in part due to the challenges of kinematic measurement in this region. The aim of this thesis is to contribute to the literature concerning the role of the shoulder girdle and thorax complex in neck pain from three perspectives. First, the thesis has further refined and informed measurement methods of shoulder girdle and thoracic kinematics (Studies 1-3). Secondly, the thesis further defined normative kinematics of the region with a focus on upright resting posture (Study 4). Thirdly, the thesis explored differences in shoulder girdle and thoracic resting posture in upright standing in those with and without neck pain (Study 5).Advancement in knowledge concerning normal and impaired function of the shoulder girdle has been hindered by challenges related to 3D motion capture of the shoulder girdle and thorax due to skin movement and the complexity of measuring multiple joints and axes of rotation. Therefore, Study1 focused on refining and validating an acromion marker cluster (AMC) method to track scapular movement with the intent of minimising skin movement error. Although the findings of Study 1 indicated that the refined AMC design did not appear to lessen skin movement error compared to previous designs, it was found to be of comparable accuracy (max RMSE 4.45°) and reliability to previous designs (within-session test-retest ICC 0.79-0.99) and appropriate for use in the subsequent thesis studies. In Study 2 the reliability and validity of the AMC method was further evaluated in its capacity to track the scapula at end range clavicular movements (protraction/retraction, elevation/depression). Establishing its measurement accuracy and reliability (max RMSE 6.6°) in these common directions of scapula motion was necessary as it had been previously unstudied. While Studies 1 and 2 focused on optimising the measurement of scapulothoracic kinematics by ensuring the scapula could be tracked accurately, Study 3 focused on refining the measurement of the relationship between the shoulder girdle and the underlying thorax. This study compared thoracic and shoulder girdle postural relationships expressed in the external reference frame to that expressed in the traditionally used ISB recommended thorax reference frame. Using these different frames of iii reference Study 3 also compared measures of thoracic inclination and thoracic curvature. The findings sho...
