    Hand grip dynamometry is a simple test that can detect reduced grip strength in malnutrition. However, it is not a replacement for other nutritional status assessments.

    Area of Science:

    • Clinical Nutrition
    • Physiology

    Background:

    • Malnutrition is a significant concern in patient care.
    • Assessing nutritional status is crucial for effective treatment.
    • Hand grip dynamometry is a potential tool for nutritional assessment.

    Purpose of the Study:

    • To evaluate the utility of hand grip dynamometry in assessing nutritional status.
    • To compare grip strength in normally nourished, malnourished, and catabolic patients.

    Main Methods:

    • Hand grip strength was measured using a dynamometer in 109 normally nourished and 26 malnourished patients.
    • Grip strength was analyzed in relation to nutritional status, age, and sex.
    • Correlation with other nutritional status indices was assessed.

    Related Experiment Videos

    Main Results:

    • Grip strength was significantly lower in catabolic men and women compared to normal individuals (P < 0.001 for men, P = 0.083 for women).
    • Grip strength decreased with age, particularly in women (P < 0.05).
    • High correlation was observed between right and left hand grip strength, but not with other nutritional markers.

    Conclusions:

    • Hand grip dynamometry is a quick, easy, and reproducible test.
    • Reduced grip strength is indicative of malnutrition.
    • Hand grip dynamometry cannot replace comprehensive nutritional status assessments.
