Given that muscle strength has general characteristics, the handgrip strength test may often indicate general muscular strength.

A review of the value of the handgrip strength test in dialysis patients found this test to correlate with general muscle mass, nutritional status (of importance in dialysis), and future complications (Leal et al. 2011). A review of 114 studies in the general population and 71 studies with arthritic patients found a strong...
