 Lots of us have been there. We get injured and we are given some exercises to perform to help our rehabilitation. But if we are honest, very few of us do them. Sometimes we can't remember. Sometimes we have other priorities. Sometimes we're just not sure if we're doing it right. So what if technology could help? Healthcare is changing and we need to reimagine the way we receive this care. After operations we spend less time in hospital and these hospitals are finding more innovative and efficient ways to offer care with an increasing emphasis on self-management by you, the patient. Boomerang is a mobile technology platform that aims to support you in your recovery after surgery. The concept allows you to not only track how much you do your exercises but also tell you if you're doing them wrong and how to correct this. You're also able to learn all about your operation and recovery in an interactive way. Your physiotherapist will be able to access this software to see how much and how well you are doing your exercises in order to support you as best as possible. As part of my PhD research, I am developing and then testing this technology with a group of patients from the Beacon Hospital. This large private facility is at the forefront of technology-driven healthcare and serves the population of Notoni South Dublin for patients from all over Ireland. My research takes me from the healthcare facility into the academic setting at the Insight Centre for Data Analytics in University College Dublin. The team and Insight are working at new and exciting ways of improving healthcare delivery and human performance with the use of sensors. Boomerang will harness this sensor technology stored within the smartphone that lives in many of our pockets. This makes the concept very accessible to a lot of people and requires very little cost. All you do is strap your phone onto your leg and follow the exercises on the screen at the tablet. I will be testing this to see how user-friendly it is and to see what impact it has during rehabilitation from hip and knee replacement operations. My project forms part of the Wider Chest Network, an EU-funded research group from around Europe looking into how technology can be used to deliver better healthcare and meet the demands of the future. With 15 PhD researchers from a variety of disciplines there is an opportunity for learning from one another as well as understand healthcare in different countries, the good bits and the bad bits. Chest provides the opportunity for researchers like myself to challenge the standard practices and come up with new approaches for healthcare fit for the 21st century. I have access to a wealth of advice from very knowledgeable experts across education, healthcare and industry in order to complete my project and hopefully we will be able to make a difference and better support patients in the future.
