relative Hand grip strength
Diagnostic TestTo perform this study the relative handgrip strength (rHGS) index was used. The rHGSi is defined as the sum of the handgrip strength of both hands divided by body mass index (BMI), and it is considered a better prognostic tool than handgrip strength. rHGS was measured by Jamar hand dynamometer. The Functional Performance was determined by using 3 tests of the Senior Fitness Test (The 30-second chair stand test, the 8-feet Up-and-Go test, and the 2 minutes' Walk Test).
