The Irish Robot Helping Older People Live Independently
Gerontechnology will play a crucial role in care as fewer people opt for careers in sector, and one such Irish robot is helping older people live independently.
If you haven’t yet heard of gerontechnology or the “silver tech” space then you soon will. It will become a core aspect of both younger Boomers and Gen X’s care as they age. Silver tech encompasses everything from devices that aid independent living to apps that can predict dementia, and robots to keep us company.
This market will be worth €777 billion by 2025, according to analyst firm BBC Research. It’s no wonder: there were 703 million persons aged 65 years or over in the world in 2019 and this is projected to double to 1.5 billion by 2050.
In Ireland, there is a newly-formed Gerontechnology Hub at Tallaght University Hospital (TUH) led by consultant geriatrician Prof Sean Kennelly. He says it is vital that with longer lifespan comes a corresponding increase in health span. And technology can support this.
Kennelly explains that “one of the core pillars of TUH is technology and innovation. We have a very supportive executive group who have encouraged collaborations with tech companies to put together an expert group of developers, innovators, clinicians and patients.”
One of the first collaborations has been with Dublin City University (DCU) spin-in GaitKeeper. This app records 60-frames-per-second video footage of someone as they perform a walking test, capturing 25 core joint locations on the body. Within minutes the data is processed by the AI engine and used to calculate elements of gait – such as stride length or heel strike – that turn out to be important predictors of both physical and cognitive decline.
GaitKeeper received funding from Enterprise Ireland in 2019 to spin into DCU in order to develop a robust healthcare application for their tech. It has been part of a clinical study at TUH since November 2020, where 250 gait tests comprising 250,000 images have been processed through the AI engine, says chief executive Aidan Boran.
Boran said,“the TUG (timed up and go) test is most frequently used to understand fall risk in older people. The patient is asked to move from a seated position, walk three metres and return all the while measuring the length of time it takes. Tens of thousands of these tests are performed in Ireland on a yearly basis but it is mainly a manual process using a stop watch or similar while making notes, which has an element of subjectivity.”
Other systems might be more affordable but still require room for specialist equipment and an IT expert on hand to set it up. GaitKeeper aims for an “anytime, anywhere, anyone” approach with a smartphone app that allows the clinician to get it done in a few taps. It has been validated against the more expensive gait systems to ensure comparable accuracy.
Boran noted, “being a start-up in this area is different to the traditional route. The concept of MVP (minimal viable product) is not applicable. Who wants an MVP stent in their heart? It has been a long road of developing this product but we are now a regulated Class 1 medical device.”
What these kinds of technologies excel at is putting into concrete data what clinicians have long observed but only intuited.
How we walk is a very good indicator of our cognitive and psychological performance – just think about how we walk when we’re feeling confident or feeling sad – but we’ve never had a means of easily measuring this or extracting the data before.”
Kennelly is also working with a tech company specialising in analysing human speech patterns because, just like walking, speech is incredibly complex and a slight change can be indicative of a physical condition like Parkinson’s, a cognitive disease like dementia and even the psychological – depression or anxiety.
“Myself and colleagues in Trinity College Dublin (TCD), including Prof Richard Reilly who is in the area of neurological engineering, are particularly interested in this in relation to dementia detection. We will compare the AI’s speech analysis to that of clinical professionals like speech therapists as well as a manual analysis of digital recordings.”
Kennelly is similarly interested in the application of robotics for independent living, name checking Stevie II, the TCD-developed healthcare robot that made the cover of Time magazine in 2019 and monitoring companion assistant Mylo, created by Candace Lafleur.
Mylo is a support and companion robotic assistant whose primary role is to monitor older people so that they can live independently. He does a little bit of everything from reminding his owner to take their medication (complete with an image of where it’s kept) to initiating video calls with family and friends. His rental cost comes with in-home set-up to start, and remote set-up for the key contact person who learns how to operate Mylo from their laptop or phone.
Most importantly, Mylo allows family members to non-intrusively monitor their parent or grandparent. This robot allows for installation of third-party apps including fall detection. In the event of a fall, their contact is notified and can remotely drop into Mylo to see what’s happening.
Mylo has been trialled in a nursing home in Louth where Lafleur and her team are seeing how these robots are used on a daily basis. He was even brought into a nearby primary school to allow local pupils to get to grips with robotics and coding.
“The nursing home trial was great until suddenly the data went dark. I thought ‘Oh god, do they hate Mylo? Is he locked in a closet somewhere?’ It turns out one of the pupils had a grandparent there and taught the nurses how to back door out of his system to access YouTube. Mylo wasn’t making video calls or moving about much because the residents were binge-watching Daniel O’Donnell videos.”
Despite the wee Daniel hiccup, Lafleur says the robot is most popular for voice-activated video calls because many older people in residential care don’t have phones or certainly not smartphones. And when Mylo is done facilitating a call he goes off to charge himself before returning for his next command.
With fewer people opting for careers in care there is a need to supplement this role for the world’s aging population. The healthcare-cum-companion robot will be more common in the near future, says Lafleur. The only difference is we’ll asking Mylo to play some Oasis or Blur.
