Grip Strength Assessment

Grip strength assessment measures the maximal isometric force a person can generate by squeezing a handheld dynamometer, providing a simple, objective marker of overall muscle strength. Although the test uses only the hand, grip strength correlates with strength elsewhere in the body and serves as a convenient proxy for total muscle function, which is why it is central to the assessment of sarcopenia and frailty. Roberts and colleagues' 2011 review in Age and Ageing synthesized how grip strength is measured across clinical and epidemiological studies and proposed a standardized approach, because variation in equipment, posture, and protocol had made results hard to compare. A standard protocol specifies a seated posture with the elbow flexed at ninety degrees, the use of a calibrated dynamometer such as the Jamar or Smedley, and recording the best of several maximal efforts. Low grip strength predicts a range of adverse outcomes — disability, longer hospital stays, slower recovery, multimorbidity, and mortality — independent of age and body size. Its speed, low cost, and strong prognostic value have made it a routine component of geriatric and population health assessment.
