Researchers have developed a tracker for energy aid in Long COVID, marking a significant step in understanding how digital tools can support those living with this condition. The study, published in Nature Communications, introduces a novel app called 'Pace Me' designed to help manage energy levels in people with Long COVID. Funded by the National Institute for Health and Care Research (NIHR), the app combines a wearable activity tracker with helpful messages throughout the day, reminding users when they may be doing too much. Led by Dr. Lawrence Hayes of Lancaster University, the research team also included Dr. Nilihan Sanal-Hayes from the University of Salford and Professor Nicholas Sculthorpe from the University of the West of Scotland. The study split 250 participants equally and at random between two groups. One group used the app with a wearable tracker, providing real-time feedback and alerts when they were close to doing too much. The control group used a 'dummy' version of the app with only data entry screens (no tracking or alerts). Over six months, both groups felt better overall, with participants exceeding their energy allowance on average for around 50 days. Thirteen participants in the intervention group improved from PEM-positive to PEM-negative status, while the numbers of intervention participants reporting PEM at baseline fell by 10%. Dr. Hayes emphasized the feasibility of using digital platforms for energy management in Long COVID, suggesting that the platform could be adapted for other chronic illnesses with PEM-like symptoms, offering scalable, remote support for symptom management. However, the study also highlights the importance of tailoring digital interventions to the recovery trajectory of specific conditions, and the need for further research in conditions with more persistent symptoms.
