Summary

Predicting functional dependency in older adults is crucial. Multidimensional functional status measures are more effective than hand function tests for identifying at-risk individuals.

Area of Science:

  • Gerontology
  • Rehabilitation Science
  • Biomedical Engineering

Background:

  • Functional dependency in older adults is a significant concern.
  • Predicting risk is essential for prevention and intervention.
  • Hand function is a key component of overall functional status.

Purpose of the Study:

  • To compare the efficacy of five hand function tests in discriminating functional dependency levels in older adults.
  • To evaluate performance-based and self-reported measures of hand function.
  • To identify the most suitable instruments for assessing hand function in geriatric populations.

Main Methods:

  • Discriminant function analyses were performed on 702 older adults (mean age 76.78 years).
  • Hand function was assessed using the Williams Test of Hand Function, Williams Board, Jebsen Test of Hand Function, and grip strength.

  • Self-reported measures included the Dexterity Scale (GERI-AIMS) and multidimensional functional status (GERI-AIMS).

    • Main Results:

    • Demographic variables explained 40.8% of the variance in dependency.
    • All tested hand function measures significantly correlated with dependency.
    • The Williams Board showed the strongest correlation among hand function tests, explaining an additional 12.5% of variance.
    • Multidimensional functional status explained a greater variance (16.9%) after controlling for demographics and Williams Board performance.

    Conclusions:

    • While hand function tests are correlated with dependency, they are less effective predictors than multidimensional functional status measures.
    • The Williams Board demonstrates good discriminatory ability for hand function.
    • The findings provide criteria for selecting appropriate instruments to measure hand function and predict dependency in older adults.
