Alley et al reported cutoffs for handgrip strength associated with clinically relevant weakness in adults. The authors are from multiple institutions in the United States.
Patient selection: age >= 65 years of age
Evaluation: maximum handgrip strength in kilograms determined by a dynamometer
Criterion for clinically relevant weakness: gait speed less than 0.8 meters per second (slowness)
Parameters:
(1) sex
(2) maximum handgrip strength in kg
