Case study 2: pain relief
Project partners:
Aim: develop fabric based wearable system for the joint pain relief.EPSRC £600k; 3 years.
The need
8.75 million 400 million
• Joint pain and stiffness• Loss of productivity• Cost to healthcare system
Osteoarthritis population
How electrotherapy works for pain relief?
Gate Control TheoryStimulate the sensory nerves to prevent pain signals from reaching the brain.
Endorphin Release Theory Stimulate the motor nerves to cause to release endorphins (body’s nature pain killer).

• Avoid disease and disability – e.g. ulcer prevention, early diagnostic of cardiovascular diseases and pulmonary disease, wound infection monitoring, remote consultation
• Improve physical and cognitive functions – e.g. rehabilitation, assisted living, aid memory recall and remind the compliance with prescriptions
• Engage with life – e.g. engage with household activities, connect with others to reduce isolation
Industrial Strategy Challenge Fund (ISCF) on Healthy Ageing: government’s mission for people “to enjoy five more years of healthy, independent living by 2035 while narrowing the gap between the experience of the richest and the poorest.”
NHS Long Term Plan key themes on clinical priorities (e.g. stroke), enablers (e.g. digital and technology), and life course programmes (e.g. personalised care for people with long term conditions).
E-textile for healthcare and align with government’s priorities
Challenges to consider
• Biocompatibility and safety
• Reliability and durability
• Clinical evidence
• Regulatory
• User acceptance
• Scale up
• Cost
• Access to market
• Impact on the environment (e.g. sustainability, reuse/refreshment/recycle)
