Matos et al. Handgrip strength as a hospital admission nutritional risk screening method. Eur J Clin Nutr 2007;61:1128-35.
Patients identified as undernourished by NRS-2002 (37.9%) were older, shorter and lighter, with a lower functional capacity, a longer length of stay and a lower HGS (P<0.001). When comparing patients with lower HGS (first quartile) with those with the highest HGS (fourth quartile), this parameter revealed good sensitivity (86.7%) and specificity (70.2%) and a k=0.56.
