Hand grip strength as a proposed new vital sign of health: a narrative review of evidences

This study reviews hand grip strength (HGS) as a potential new "vital sign" for assessing overall health. HGS, measured using a handheld dynamometer, is linked to muscle function and predicts risks for conditions like heart disease, diabetes, osteoporosis, and even cognitive decline. Lower grip strength is associated with increased hospitalization and mortality. The review highlights variations in HGS across populations, emphasizing its utility as a quick, non-invasive health indicator. While the evidence is strong, standardization across different demographics remains a challenge.

To maintain brain health, prioritize strength training, particularly resistance exercises, to improve muscle function. A balanced diet rich in protein and essential nutrients can support muscle preservation. Regular handgrip strength assessments may help track overall health. However, as this study is a narrative review rather than direct clinical research, applying findings to individuals requires caution. Lifestyle adjustments should be guided by broader clinical evidence and personal health conditions.
