Handgrip Weakness and Asymmetry Independently Predict the Development of New Activity Limitations: Results from Analyses of Longitudinal Data from the US Health and Retirement Study

Examining strength asymmetries in assessments of muscle function may improve screenings for limitations in independent living tasks such as instrumental activities of daily living (IADL). We sought to determine the associations between handgrip strength (HGS) asymmetry and future IADL limitations in aging Americans.
