Objective: The 3-D posture and muscle activity in the neck and upper limb were assessed in children using high-, mid-, and book-level displays, which correspond to working conditions frequently observed when children interact with computers or books and paper. Background: The 3-D posture and muscle activity of children reading and inputting data with computers and paper had not been previously assessed. Methods: Twenty-four children aged 10 to 12 years and of normal height performed an interactive task involving reading from a book and writing on paper or reading from a computer display and inputting data using a mouse and keyboard. Results: Head and neck flexion increased as the visual target was lowered. The high display resulted in mainly upper cervical relative extension, and the book display resulted in both upper and lower cervical flexion. The book condition resulted in greater cervical erector spinae and upper trapezius activity than did the mid and high conditions. Conclusion: The data suggest that a mid-level display may be more appropriate for children than a high display (e.g., when the display is placed on top of the central processing unit). The mid display also results in a more upright and symmetrical posture and lower mean muscle activity than does working with books and paper flat on the desk. Application: This study provides short-term laboratory study evidence for the formulation of guidelines for workstation design and adjustment for children. Use of computers by children is increasing, yet ergonomic guidelines lag behind those for adults.

INTRODUCTION: Aboriginal and Torres Strait Islander (hereafter respectfully referred to as Aboriginal) people are Australia's First Peoples, having the longest continuous culture in the world and deep spiritual connections with ancestral land. Improvements in their health and well-being is a major policy goal of Australian governments, as the legacy of colonisation and disruption of cultural practices contribute to major health challenges. Lack of culturally secure services impacts participation of Aboriginal people in health services. Aboriginal people with a brain injury typically experience poor access to rehabilitation and support following hospital discharge. 'Healing Right Way' (HRW) is a randomised control trial aiming to improve access to interdisciplinary and culturally secure rehabilitation services for Aboriginal people after brain injury in Western Australia, improve health outcomes and provide the first best practice model. This protocol is for the process evaluation of the HRW trial. METHODS AND ANALYSIS: A prospective mixed methods process evaluation will use the Consolidated Framework for Implementation Research to evaluate implementation and intervention processes involved in HRW. Data collection includes qualitative and quantitative data from all sites during control and intervention phases, relating to three categories: (1) implementation of trial processes; (2) cultural security training; and (3) Aboriginal Brain Injury Coordinator role. Additional data elements collected from HRW will support the process evaluation regarding fidelity and intervention integrity. Iterative cross-sectional and longitudinal data synthesis will support the implementation of HRW, interpretation of findings and inform future development and implementation of culturally secure interventions for Aboriginal people. ETHICS AND DISSEMINATION: This process evaluation was reviewed by The University of Western Australia Human Research Ethics Committee (RA/4/20/4952). Evaluation findings will be disseminated via academic mechanisms, seminars at trial sites, regional Aboriginal health forums, peak bodies for Aboriginal health organisations and the Australian Indigenous HealthInfoNet (https://healthinfonet.ecu.edu.au/).
