Grip Strength Measurement: A Critical Review of Tools, Methods, and Clinical Utility
Critical Reviews in Physical and Rehabilitation Medicine
Isometric grip strength can be correlated with upper extremity and overall body strength. Changes in grip strength can be good indicators of the need for and the efficacy of rehabilitative treatment. The measurement of grip strength is a quick and easy assessment tool that, if standard protocol is followed, can be measured with a reasonable amount of reliability and validity. Instruments used to measure grip strength, although many and varied, are readily available and easy to use.
Many variables must be considered when measuring grip strength, such as upper extremity and body position, proper choice of instrument, number and duration of trials, and age, sex, and impairment state of the individual to be tested. In this review, we address the variables that potentially affect the reliability and validity of measurement of grip strength and the implications for clinically interpreting grip strength data.
