Nutritional assessment by hand grip dynamometry.
Hand grip dynamometry was studied in 109 normally nourished and 26 malnourished patients. The grip strength was 37,5 +/- 9,9 kg/m2 in normal men, 30,5 +/- 14,4 kg/m2 in men with carcinoma of the oesophagus (starvation-adapted) and 22,0 +/- 9,2 kg/m2 in catabolic men (P less than 0,001). Normal women had a grip strength of 31,6 +/- 7,5 kg/m2 compared with 22,3 +/- 7,0 in catabolic women (P = 0,083). Hand grip dynamometry fell with age (r = 0,69 men; r = 0,57 women), although the correlation was only statistically significant in women (P less than 0,05). There was a strong correlation between right and left hand grip (r = 0,84 men; r = 0,86 women), but hand grip did not correlate well with other indices of nutritional status. Although hand grip dynamometry is a quick, easy and reproducible test, and grip strength is reduced in malnutrition, it cannot replace other tests of nutritional status.
