PGI launches affordable AI device for neuropathic pain diagnosis

In Chandigarh, a new medical device developed by PGI is poised to change the way neuropathic pain is diagnosed in India. This device, called the Quantitative Sensory Testing (QST) device, uses artificial intelligence (AI) and is expected to make healthcare more accessible. Neuropathic pain affects millions of people, particularly those with conditions like diabetic neuropathy and sciatica. The traditional QST method has been expensive, with imported versions costing around Rs 40 to 50 lakh. This has made it difficult for many to receive proper diagnosis and treatment. Dr. Babita Ghai, from the anaesthesia and intensive care department, created a portable version of the QST device. It is expected to cost only Rs 2 lakh, with hopes for even lower prices through mass production. Dr. Ghai aims to provide advanced healthcare to community providers. She believes that making the technology affordable and easy to use will help in early detection and better patient outcomes. The new AI-powered device tests seven important factors, such as temperature and pressure, and provides results in just 20 to 30 minutes. This is faster than traditional methods, which require extensive analysis by trained technicians. Dr. Ghai emphasizes the importance of early diagnosis to prevent irreversible nerve damage. The project received support from the Center of Innovation and Biodesign (CBIOD) and Thapar Institute. Initial funding for the patent came from CBIOD. The team is now seeking more support from the Indian Council of Medical Research (ICMR) to further develop this promising technology.
