Scientists are developing a smart textile band that can objectively detect and monitor sarcopenia, an age-related condition defined as loss of muscle mass, function and power.
Experts from Nottingham Trent University, Newcastle University and Axomics Medical, supported by funding from Wellcome Leap’s global Dynamic Resilience program and the Temasek Trust, are aiming to reduce the progression to frailty in those over the age of 65 by 25%, improving the quality of life for older people.
The wearable device, known as the Axoband, will feature fully screen-printed flexible electrodes to measure electrical signals generated by the muscles and includes an embedded electronic sensor capable of tracking movement.
The project is being led by Professor Yang Wei in Nottingham Trent University’s Medical Technologies Innovation Facility and is underpinned by earlier work led by Dr Annette Pantall, Co-Principal Investigator, CEO of Axomics Medical, and formerly of Newcastle University.
Sarcopenia impacts upwards of ten percent of people over 60 and is as common as type 2 diabetes and is associated with reduced mobility and an increased risk of falls.
There is also a high economic burden, with muscle weakness and associated falls estimated to cost the UK alone £2.5bn a year. The number of people diagnosed globally is forecast to rise by more than a quarter in the next 25 years as the population ages.
Despite its prevalence, however, sarcopenia remains difficult to diagnose due to the lack of objective, quantitative tools, something which also hampers the development of effective treatments aimed at improving muscle mass and function.
The Axoband, designed to be worn on the leg, will be low cost to manufacture, stretchable and washable.
Bespoke software will process signals recorded from the band during clinical tests and will provide a quantitative measure of muscle health and an app will indicate the probability that the patient has sarcopenia. Having an accurate method of diagnosis and monitoring progression will enable clinicians to start treatment sooner, as well as identifying effective treatments, which can include nutritional, exercise and pharmaceutical interventions. This will help reduce the severity or delay the onset of clinical frailty.
“There is currently no quality way to diagnose, monitor and assess sarcopenia,” said Yang Wei, principal investigator and Professor of Wearable Technology in NTU’s Nottingham School of Art & Design and the academic lead of smart medical textiles in Medical Technologies Innovation Facility (MTIF). “With sarcopenia becoming a growing problem in an ageing population, this is crucial in ensuring people are diagnosed more quickly and efficiently, allowing the right measures to be put in place as soon as possible.”
Dr Annette Pantall, who laid the groundwork for this new phase of development, said, “This innovative device will make a tremendous difference to the quality of life of older adults and also to people with muscle loss associated with chronic diseases such as diabetes, liver disease, chronic obstructive pulmonary disease and cancer.”
