Exploring Lumbar Postural Behaviours in Healthy Adults:
A Comparison of Laboratory and Real-world Measures

THANK YOU for your interest in participating in this research project. Please read the following information about the project, so that you can decide whether you would like to take part in this research.

What is this research about?
We aim to investigate whether you move differently when comparing between the measures performed in the laboratory with the measures performed in the “real-world”, and whether the wearable devices (motion sensors) used to make these measures are accurate.

Who are the researchers conducting the study?
This research project has been designed by researchers from the Human Neuroscience Unit and NHMRC Centre of Clinical Research Excellence in Spinal Pain, Injury and Health, The University of Queensland. The investigators team include: Mr Mansour Alshehri, Dr Manuela Besomi, Dr Ryan Riddick, Dr Wolbert van den Hoorn, Dr David Klyne and Prof Paul Hodges.

Who can participate?
You can participate in this study if you meet the eligibility criteria. The final decision on the eligibility for participating in this study will be made after completing this survey.

What will I need to do?
If you agree to participate and meet the eligibility criteria, a researcher will contact you to schedule a time that suits you best to attend a laboratory session lasting ~1-2 hours. On initial setup, you will be fitted with custom wearable sensors placed on the skin over regions on your trunk and thigh to record hip and trunk posture/movement. Then, you will be asked to perform a series of tasks, including sitting, standing, and functional tasks, as well as balance tasks while sitting on an unstable platform during the laboratory session. At the end of this session, the same sensors will be replaced with alternative sensors to record the real-world (e.g., in your natural environment) measures over the next 48 hours. You will also be asked to download a free application on your smartphone. We will use this app to gather information related to your physical activity and habits over the 48-hour period, such as time woke up, time got up, time went to bed, time went to sleep, other sleep times, time of standardised movements, work time, and any removal. A reminder to complete the diary will be sent every 90 minutes. You will be asked to return these sensors the next second day (after 48 hours) at the same location (St Lucia’s campus, School of Health and Rehabilitation Sciences, The University of Queensland). Data will be extracted from the sensors at the end of the study to quantify body habitus (e.g., sit, stand, lying, walking) and trunk posture/movement.

What are the possible benefits of taking part?
You will receive a cash payment of $40 AUD for your participation (on study completion) as remuneration.

What are the possible risks and disadvantages of taking part?
This study has been designed to address our aims in such a manner that the participants are exposed to the minimum possible degree of risk, inconvenience, and discomfort. However, you will have the opportunity to withdraw from these procedures at any time should you wish to do so, without penalty. If your data are used for additional analyses, your privacy will be maintained at all times. There is a small risk of some skin irritation from fixation of the wearable sensors for measuring movement/posture in some people.

What will happen to the information about me?
All information collected about you will remain confidential. You will be assigned a number with which all data forms, pertaining to you, will be labelled. Files will be kept in a locked filing cabinet in the School of Health and Rehabilitation Sciences at the University of Queensland. The information gathered through the mobile will be stored in a secured institutional server with a protected password that only the investigators will have access. Collected data might be used for future research upon reasonable request, but your privacy will be maintained at all times. It is anticipated that the results of this research project will be published and/or presented in a variety of forms. In any publication and/or presentation, information will be provided in such a way that you cannot be identified.

What will happen if I decide to withdraw?
Your participation in this research is voluntary and you are free to withdraw from the research anytime without needing to provide any explanation, and you would not receive any penalty or bias as a result of your withdrawal. If you choose to stop participating, you will be asked to inform us whether you are happy or not for us to retain the data that we have already collected. If you do not agree to this, the data will be deleted.

Can I hear about the results of this research?

Feedback on individual assessment results can be provided on request and a summary of the overall outcomes of the study will be available at the completion of the research project.

Can I have further information about this research?
If you have any questions regarding the nature of the research or need assistance to complete this survey, please feel free to contact Mr Mansour Alshehri (, Dr David Klyne ( or Professor Paul Hodges ( who will be happy to provide you with further information.
