Diagnostic power of relative sit-to-stand muscle power, grip strength, and gait speed for identifying a history of recurrent falls and fractures in older adults

Key summary points Aim To compare the diagnostic value of relative sit-to-stand muscle power with grip strength or gait speed for identifying a history of adverse outcomes in older adults. Findings When compared to grip strength or gait speed, relative sit-to-stand muscle power offered slightly (but not statistically) higher diagnostic power for identifying a history of recurrent falls and fractures in older adults. However, all tests showed low diagnostic power (AUC
