Comparison of two handgrip dynamometers in older adults before elective surgery.

Background: Handgrip strength is a useful measurement of muscle strength and has been proposed as a single predictor of postoperative outcomes in older adults. The aim of this study was to assess the correlation and concordance of Camry digital hand grip dynamometer (EH101) with gold standard Jamar® hydraulic handgrip dynamometer in older adults previous to elective surgery.

Methods: A cross-sectional study was conducted on patients ≥ 65 years old admitted to a Chilean private hospital for elective surgery between March 2018 and February 2019.
