Hand grip strength measurement in different epidemiologic studies using various methods for diagnosis of sarcopenia: a systematic review

Abstract

Background The purpose of this systematic review was to compare various methods for measuring hand grip strength to provide data for the development of a standardized protocol for such a measurement based on epidemiologic studies of sarcopenia in older population. Methods Systematic review and meta-analysis were performed using 34 available epidemiologic studies. Results The choice of hand dynamometer and measurement protocols for measuring hand grip strength was not consistent among studies. Mean values of hand grip strength in older population were also different by study area (Europe, America, and Asia) and gender. Conclusion This systematic review demonstrated that various grip strength measurement methods were used in different epidemiologic studies. A standardized method is needed to enable more consistent measurement of grip strength and better assessment of sarcopenia.
