The health of movement recognising movement choices in individuals for long-term health
No full textChanges in movement quality, specifically how people coordinate movement, have been identified in people with pain, history of pain and linked to risk of injury, changes in performance and quality of life. The health of movement is a balance between how an individual uses their body to engage with life and an ability to display choices in movement coordination strategies (MCS). The aim of this thesis is to explore the concept that assessing and retraining MCS improves the health of movement. Five core publications are included: two theoretical papers detailing the concept for assessing and retraining MCS; one reliability study establishing robustness of an assessment tool; a case report demonstrating validity and proof-of-concept of assessment andretaining of MCS; and a morphological study of the serratus anterior muscle illustrating knowledge of anatomical architecture can shape retraining strategies.The commentary includes the following topics: i) theoretical concept for assessing and restoring the health of movement (Chapter 2); ii) aspects of anatomy and neurophysiological function to support methods of assessment and retraining (Chapter 3); iii) assessment of loss of movement choices (LMC) using cognitive movement control tests to inform retraining (Chapter 4); iv) cognitive movement retraining/movement coaching, a person-centred clinical reasoningframework to design individual tailored programmes to restore LMC (Chapter 5); v) General discussion - significance, implementation and impact, illustrated over 25 years (Chapter 6).Results have demonstrated: i) good inter-rater and excellent intra-rater reliability for the assessment tool; ii) testing for LMC can inform retraining and cognitive movement retraining can change biomechanical and neurophysiological measures; and iii) novel findings of morphologicallydistinct subdivisions of serratus anterior.This thesis recommends the assessment of MCS to guide retraining to improve the health of movement. Theoretical concepts presented and research conducted have provided evidence for proof-of-concept and validity and reliability of assessment procedures<br/
Assessment of movement coordination strategies to inform health of movement and guide retraining interventions
No full textIntroductionExploring characteristics of human movement has long been the focus of clinicians and researchers. Changes in movement coordination strategies have been identified in the presence of pain highlighting the need for assessment in clinical practice. A major development in the understanding of movement related disorders is recognition of individual differences in presentation and consequently the need to tailor interventions based on assessment.PurposeThe purpose of this masterclass is to build a rationale for the clinical assessment of movement coordination strategies, exploring loss of movement choices, coordination variability, and to present a clinical framework for individualised management, including the use of cognitive movement control tests and retraining interventions. An approach for the qualitative rating of movement coordination strategies is presented. A compromised movement system may be one characterised by a lack of ability to access motor abundance and display choice in the use of movement coordination strategies. The identification of lost movement choices revealed during the assessment of movement coordination strategies is proposed as a marker of movement health.Implications for practiceThe health of the movement system may be informed by the ability to display choice in movement coordination strategies. There is evidence that restoring these choices has clinical utility and an influence on pain and improved function. This approach seeks to provide individuals with more flexible problem solving, enabled through a movement system that is robust to each unique challenge of function. This assessment framework sits within a bigger clinical reasoning picture for sustained quality of life
A novel cadaveric study of the morphometry of the serratus anterior muscle: one part, two parts, three parts, four?
No full textThe serratus anterior is portrayed as a homogeneous muscle in textbooks and during functional activities and rehabilitation exercises. It is unclear whether the serratus anterior is composed of subdivisions with distinctive morphology and functions. The purpose of this study was to determine whether the serratus anterior could be subdivided into different structural parts on the basis of its segmental architectural parameters. Eight formalin-embalmed serratus anterior muscles were dissected and the attachments of each fascicle documented. Orientation and size of each fascicle were measured and the physiological cross-sectional area (PCSA) calculated. Three subdivisions of the 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 cm2) and attached, with the rib 3 fascicle, along the medial border of the scapula to form the middle division. The rib 2 superior and rib 1 fascicles attached to the superior angle of the scapula (upper division). Fascicles from ribs 4–8/9 attached to the inferior angle of the scapula (lower division). Mean fascicle angle relative to a vertical midline reference and PCSA for each division were 29° and 1.3 cm2 (upper), 90° and 2.2 cm2 (middle) and 59° and 3.0 cm2 (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
Movement control testing of older people in community settings: description of a screening tool and intra-rater reliability
No full textObjective: To determine the intra-rater reliability of a newly developed movement screening tool; the ‘Movement control screen for older people in community settings’. The movement screening tool aims to identify movement control impairments which can potentially influence movement function. Method: Thirty one active female recreational golfers, aged 65-77 years,carried out three movement control tests included in the screening tool. Performance was videorecorded to enable repeated ratings. Each test was evaluated by criteria which were rated as pass or fail and ratings were carried out three weeks apart to examine intra-rater reliability. Reliability was assessed using percentage agreement and Cohen’s Kappa. Results: Percentage agreementfor each test ranged from 93.0-97.3%, with an overall mean agreement of 95.5%. Kappa values for test scores ranged from 0.35-0.90. Percentage agreement for individual criteria ranged from 83.0-100.0%, with kappa values ranging from 0.00-1.00. Discussion: Acceptable intra-rater reliability was established for overall tests scores of the screening tool but certain criteria wereidentified as being less reliable than others. Recommendations are made for refinement of some criteria to improve reliability of the screening tool.<br/

No full textIntra and inter-rater reliability of screening for movement impairments: movement control tests from the foundation matrix
No full textPre-season screening is well established within the sporting arena, and aims to enhance performance and reduce injury risk. With the increasing need to identify potential injury with greater accuracy, a new risk assessment process has been produced; The Performance Matrix (battery of movement control tests). As with any new method of objective testing, it is fundamental to establish whether the same results can be reproduced between examiners and by the same examiner on consecutive occasions. This study aimed to determine the intra-rater test re-test and inter-rater reliability of tests from a component of The Performance Matrix, The Foundation Matrix. Twenty participants were screened by two experienced musculoskeletal therapists using nine tests to assess the ability to control movement during specific tasks. Movement evaluation criteria for each test were rated as pass or fail. The therapists observed participants real-time and tests were recorded on video to enable repeated ratings four months later to examine intra-rater reliability (videos rated two weeks apart). Overall test percentage agreement was 87% for inter-rater reliability; 98% Rater 1, 94% Rater 2 for test re-test reliability; and 75% for real-time versus video. Intraclass-correlation coefficients (ICCs) were excellent between raters (0.81) and within raters (Rater 1, 0.96; Rater 2, 0.88) but poor for real-time versus video (0.23). Reliability for individual components of each test was more variable: inter-rater, 68-100%; intra-rater, 88-100% Rater 1, 75-100% Rater 2; and real-time versus video 31-100%. Cohen’s Kappa values for inter-rater reliability were 0.0-1.0; intra-rater 0.6-1.0 for Rater 1; -0.1-1.0 for Rater 2; and -0.1-1 for real-time versus video. It is concluded that both inter and intra-rater reliability of tests in The Foundation Matrix are acceptable when rated by experienced therapists. Recommendations are made for modifying some of the criteria to improve reliability where excellence was not reached
The assessment of movement health in clinical practice: a multidimensional perspective
No full textThis masterclass takes a multidimensional approach to movement assessment in clinical practice. It seeks to provide innovative views on both emerging and more established methods of assessing movement within the world of movement health, injury prevention and rehabilitation. A historical perspective of the value and complexity of human movement, the role of a physical therapist in function of movement health evaluation across the entire lifespan and a critical appraisal of the current evidence-based approach to identify individual relevant movement patterns is presented. To assist a physical therapist in their role as a movement system specialist, a clinical-oriented overview of current movement-based approaches is proposed within this multidimensional perspective to facilitate the translation of science into practice and vice versa. A Movement Evaluation Model is presented and focuses on the measurable movement outcome of resultants on numerous interactions of individual, environmental and task constraints. The model blends the analysis of preferred movement strategies with a battery of cognitive movement control tests to assist clinical judgement as to how to optimize movement health across an individual lifespan.</p
Retraining in a female elite rower with persistent symptoms post-arthroscopy for femoroacetabular impingement syndrome: a proof-of-concept case report
No full textAthletes with femoroacetabular impingement syndrome (FAIS) managed arthroscopically do not always return to sport. Inability to control back/pelvis, hip and lower limb movements may contribute to the onset and recurrence of symptoms. Our hypothesis is that results from a battery of cognitive movement control tests can inform a cognitive movement control (neuromuscular) retraining programme for improving the clinical presentation and quality of life in an athlete with FAIS. This case report presents a female elite rower with persistent left-sided anterior hip pain, four years post-arthroscopic surgery for FAIS, whose symptoms failed to respond to conventional physical therapy. Hip and groin outcome score (HAGOS), passive and active hip flexion range of motion (ROM) workload (time training on water), hip and pelvic kinematics (3-D motion analysis) and electromyography during a seated hip flexion movement control test, and a movement control test battery to identify movement control impairments (The Foundation Matrix), were assessed preintervention (week 0) and immediately post-intervention (week 16). Impaired movement control was targeted in a tailored 16-week cognitive movement control retraining exercise program. All measures improved: HAGOS (all 6 sub-scales); symptoms (61/100 pre-training to 96/100 posttraining); physical activities participation (13/100 to 75/100); and active hip flexion ROM increased(78 to 116 and 98 to 118 degrees, respectively); workload increased from 4 to 18 h/week; and movement control impairment reduced (25/50 to 9/50). Pelvic motion on kinematic analysis were altered, and delayed activation onset of tensor fascia latae and rectus femoris muscles reduced. This proof-of-concept case report supports the hypothesis that cognitive movement control tests can inform a targeted cognitive movement control retraining program to improve symptoms, function and quality of life, in an elite rower with persistent hip pain. This training offers an alternative approach to conventional physical therapy, which has failed to restore function in FAIS, and the present study illustrates how specific cognitive movement control assessment can direct individual training programmes
