Abstract: Handgrip strength (HGS) asymmetry may help identify the functional asymmetries that contribute to mobility limitations. We sought to determine the associations of HGS asymmetry on gait speed and standing balance in older Americans. The analytic s le included 8,396 adults aged ≥65-years for the last wave in which they participated in the 2006-2016 Health and Retirement Study. Participants were categorized into asymmetry groups based on the degree of HGS asymmetry. Persons with gait speed 30.0% asymmetry had 1.23 (CI: 1.05-1.44) greater odds. Persons with 10.1%-20.0%, 20.1%-30.0%, and >30% asymmetry had 1.09 (CI: 1.07-1.22), 1.23 (CI: 1.07-1.42) and 1.40 (CI: 1.22-1.61) greater odds for poorer static balance, respectively. Those in each in idual asymmetry group had greater odds for slow gait speed: 1.14 (CI: 1.03-1.26) for >10.0%, 1.19 (CI: 1.07-1.33) for >20.0%, and 1.16 (CI: 1.01-1.35) for >30.0%. Similar results were observed for poorer balance: 1.20 (CI: 1.09-1.32) for >10.0%, 1.27 (CI: 1.15-1.41) for >20.0%, and 1.31 (CI: 1.16-1.49) for >30.0%. Every 10% asymmetry increase was associated with 1.62 (CI: 1.32-1.99) greater odds for poorer balance. The bimanual aspects of HGS asymmetry may reflect the bilateral movements required for mobility, and the relationship between upper and lower extremity strength and function may elucidate our findings.

Abstract: Evaluating handgrip strength (HGS) asymmetry may help to improve the prognostic value of HGS. This study sought to determine the associations of HGS asymmetry and weakness on future activities of daily living (ADL) disability in a national s le of aging Americans. The analytic s le included 18,468 Americans aged ≥50 years from the 2006–2016 waves of the Health and Retirement Study. A handgrip dynamometer measured HGS. Those with HGS & % stronger on either hand were considered as having any HGS asymmetry. In iduals with HGS & % stronger on their dominant hand were considered as having dominant HGS asymmetry, while those with HGS & % stronger on their nondominant hand were classified as having nondominant HGS asymmetry. Men with HGS & kg and women with HGS & kg were considered weak. ADLs were self-reported. Generalized estimating equations were used for analyses. Relative to those with symmetric HGS and no weakness, each HGS asymmetry and weakness group had increased odds for future ADL disability: 1.11 (95% confidence interval [CI]: 1.02–1.20) for any HGS asymmetry alone, 1.42 (CI: 1.16–1.74) for weakness alone, and 1.81 (CI: 1.52–2.16) for both any HGS asymmetry and weakness. Most weakness and HGS asymmetry dominance groups had increased odds for future ADL disability: 1.30 (CI: 1.13–1.50) for nondominant HGS asymmetry alone, 1.42 (CI: 1.16–1.74) for weakness alone, 1.72 (CI: 1.29–2.29) for both weakness and nondominant HGS asymmetry, and 1.86 (CI: 1.52–2.28) for both weakness and dominant HGS asymmetry. HGS asymmetry and weakness together may increase the predictive utility of handgrip dynamometers.
