Grip strength is measured using a hand dynamometer (such as a Jamar) with the subject seated, their elbow by their side and flexed to right angles, and a neutral wrist position, the dynamometer handle position adjusted to comfortably fit the subject's hand size. The mean of three trials is recorded.
Grip strength is a useful indicator of possible sarcopaenia.
Hand grip strength in kg force – mean and (standard deviation).
