Innovative wearable rehabilitative device to help people with mobility needs
A “ground-breaking” new project developed by scientists at the University of Bristol could help people with reduced mobility walk and move from sitting to a standing position in comfort and safety.
The FREEHAB project will develop soft, wearable rehabilitative devices, which will act as artificial muscles, to help elderly and disabled people live more independent lives.
Led by University of Bristol Professor of Robotics Jonathan Rossiter, FREEHAB builds on discoveries from his previous Right Trousers project, which saw his team develop new soft materials that could be used like artificial muscles.
Professor Rossiter said: “There are over 10.8 million disabled people living in the UK today. Nearly 6.5 million have mobility impairments. These numbers are growing as the median population age increases and age-related mobility issues due to conditions such as arthritis and stroke become more prevalent.”
The materials from which the artificial muscles are made include 3D-printable electroactive gel materials, and soft but strong pneumatic chains that change shape when inflated and can exert considerable force.
Professor Rossiter added: “Together with integrated sensing technology, we will make devices that physiotherapists can use to accurately pinpoint limitations in their patients’ movements, thus enabling them to plan personalised training programmes.
“We will also make simpler devices that the patient can use to enhance their mobility activities and exercise with confidence when a therapist is not with them.”
To develop the project, the researchers will work with physiotherapists in the NHS and private practices, and with people who have undergone physiotherapy for their mobility problems.
Following research and development, the aim is to conduct clinical trials and then bring the devices into the supply chain once the project is over.
The three-year FREEHAB project, due to start in September, has received £1,162,224 funding from the Engineering and Physical Sciences Research Council (EPSRC).
Philippa Hemmings, head of Healthcare Technologies at EPSRC, commented: “The work supported within the FREEHAB project will increase the ability of physiotherapists to support people with mobility impairments. It shows the power of engineers and physical scientists working in collaboration with partners, something our Healthcare Impact Partnership awards were set up to support.”
