This pilot study explored the potential of point-of-care ultrasound (POCUS) for diagnosing sarcopenia in older adults in the Emergency Department (ED). Involving 60 patients over the age of 65, the study measured muscle thickness of the femoral quadriceps via POCUS and assessed functional strength through grip strength and a 6-meter walk test. Results showed that 50% of participants exhibited signs of sarcopenia, with a significant correlation found between muscle thickness and functional performance. The findings suggest that POCUS could be a valuable tool for identifying sarcopenia in the ED, potentially aiding in fall prevention and reducing morbidity among this vulnerable population. Further research is necessary to validate these results.
