A Review of Handgrip Strength and its Role as a Herald of Health

Abstract

Measurement of grip strength using a handheld dynamometer is frequently performed as part of an orthopedic upper extremity examination. We review the technique of grip strength measurement and evaluation of the possible submaximal effort. What constitutes normal grip strength in one part of the world is not necessarily normal elsewhere. Additionally, there is considerable evidence, most of which is outside the orthopedic literature, that diminished grip strength is a proxy for poor health and a predictor of increased mortality.
