To define low grip strength, Fried's original frailty criteria uses < 20kg for women, and < 30kg for women. Are these cut-off points still relevant in the modern literature? Similarly, what are the best cut-off points to define low walking speed?
Yes, the cut-off points for low grip strength are still valid, but they are
For walking speed, the threshold is the time the patient needsto walk15 feet.
In men:
=oror= 7 seconds
>173 cm is >or= 6 seconds
In women
=oror= 7 seconds
=oror= 6 seconds
For grip strength the threshold is also vairable according to gender and BMI
Thus, in men:
BMI = or< 24 it is =or
