Frailty is also associated with sarcopenia, for which handgrip strength measurement has been recommended for diagnostic purposes. Specific cutoff points for diagnosis have been identified, but use of different devices may affect measurement. Therefore to assess validity and reliability, we compared the two most frequently used devices, the Jamar hydraulic and Smedley spring handgrip dynamometers.<h4>Methods</h4>Sixty-seven older (76.2 ± 0.9 years) men (n = 34) and women (n = 33) completed two trials of handgrip strength measurement on sequential days (T1, T2) using both devices in random oPloS onee0270132https://www.ebi.ac.uk/biostudies/studies/S-EPMC9212147biostudies-literatureValidity and reliability of handgrip dynamometry in older adults: A comparison of two widely used dynamometers.PMC9212147Silva-Smith ALSpicher JMBenton MJfalseValidity and reliability of handgrip dynamometry in older adults: A comparison of two widely used dynamometers.<h4>Background</h4>Among older adults, decreased handgrip strength is associated with greater risk of frailty, and loss of physical function, mobility, lean mass, and overall muscular strength and power.
