“…ICC values between the methods also reduced at 90° and 120° humeral flexion, mainly in anterior/posterior tilt of the scapula (ICC 0.62 and 0.3, respectively). The larger error above 90° humeral flexion observed in the current study and previous studies Lempereur et al, 2012;van Andel et al, 2009;Warner et al, 2012) reinforce the idea that AMC methods are prone to error in these more elevated humeral positions, even when design is optimized to reduce impact of skin movement and soft tissue artefacts. It should be noted that the scapular anatomical landmarks were only calibrated to the AMC when arms were in resting position in this study.…”

“…The SEM and MDD values for all scapular rotations at the different angle of humeral flexion are displayed in Table 3.4-2. Lempereur et al, 2012;van Andel et al, 2009;Warner et al, 2012).

“…Adequate spacing between markers allows a consistent capture of the markers by the cameras (Lempereur et al, 2014) and accuracy is increased when markers are further apart. This has led to the development of two types of AMC designs: A large base to which markers are directly attached (Warner et al, 2012) and a small base with markers mounted on pins (Lempereur et al, 2012;van Andel et al, 2009) (Figure 2.3). However, although both designs allow distance between the markers, several issues have been flagged as potentially affecting the accuracy of the AMC.…”

“…However, the AMC method is still considered to be inaccurate due to skin movement and soft tissue error with arm elevation above 90° Picco et al, 2010;Prinold et al, 2011;van Andel et al, 2009;Warner et al, 2012). Several AMC designs have been used in the past reporting various measurement errors due to skin movement (Lempereur et al, 2012;van Andel et al, 2009;Warner et al, 2012). It is suggested that implementation of the latest recommendation regarding the construction of the AMC design (Lempereur et al, 2014;Warner et al, 2012) and the accumulated knowledge from previously studied AMC designs combined with recommended attachment location will improve the accuracy of the AMC design by reducing skin movement error.…”

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...

“…Upper limbs kinematics have been widely studied in healthy, hemiplegic children or children with OBPP during functional movements (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20). However, to our knowledge, scapulothoracic, scapulohumeral and elbow joints have never been simultaneously studied in children with OBPP.…”

Abstract:Background: The physical signs of obstetrical brachial plexus palsy range from temporary upper-limb dysfunction to a lifelong impairment and deformity in one arm. The aim of this study was to analyze the kinematics of the upper limb and to evaluate the contribution of glenohumeral and scapulothoracic joints of obstetrical brachial plexus palsy children.Methods: Six children participated in this study: 2 males and 4 females with a mean age of 11.7 years. Three patients had a C5, C6 lesion and 3 had a C5, C6, C7 lesion. They were asked to perform the five tasks based on the Mallet scale and the kinematic data were collected using the Fastrak electromagnetic tracking device. ACCEPTED MANUSCRIPT A C C E P T E D M A N U S C R I P T 2Findings: The scapulothoracic protraction and posterior tilt were significantly increased in the involved limb during the tasks Hand to mouth (p=0.006 and p=0.015 respectively). he scapulothoracic Protraction/glenohumeral Elevation ratio was significantly increased in the involved limb during the hand to neck task (p=0.041) and the elevation task (p=0.015). The ratios of scapulothoracic Tilt on the three glenohumeral excursion angles were significantly increased during the hand to mouth task (p≤0.041). The scapulothoracic Mediolateral/glenohumeral Elevation ratio was significantly increased in the involved limb during the elevation task (p=0.038). The glenohumeral elevation excursion was significantly decreased in the involved limb during the hand to neck task (p<0.001) and the elevation task (p=0.0003).Interpretation: This study gives us information about the greater contribution of the scapulothoracic joint to shoulder motion for affected arm of obstetrical brachial plexus palsy patients compared to their unaffected arm. Kinematic analysis could be useful in shoulder motion evaluation during the Mallet score and to evaluate outcomes after surgery.
