The original tool was created by Nye et al. 2017 for a point-of-care decision making for clinicians suspecting a potential stress fracture. It considers physiological and hormonal risk factors that affect bone density, symptoms and a physical assessment. The initial assessment can be used by clinicians to decide whether to refer to an appropriate physician and imaging. A follow-up study in 2020 by Nye et al. found a score >=3 for injuries below the femoral condyles to have a 97.5% sensitivity, 54.2% specificity, and 98.2% negative predictive value (ruling out).
