Joint impairment significantly impacts elderly hand function, specifically grip strength. Reduced grip strength, in turn, negatively affects performance on the Williams Test (M), indicating functional decline.

Area of Science:

  • Gerontology
  • Musculoskeletal Health
  • Rehabilitation Science

Background:

  • Hand function is crucial for independence in the elderly.
  • Joint impairment is common in older adults and may affect hand function.
  • Understanding factors influencing hand function is vital for targeted interventions.

Purpose of the Study:

  • To determine the contribution of joint impairment to hand function in the elderly.
  • To analyze the relationship between joint impairment, grip strength, and the Williams Test (M) using a multivariate model.

Main Methods:

  • Cross-sectional observational study of 541 individuals over 60 years old.
  • Data collected included sociodemographics, joint impairment measures, comorbidities, pain, and mental health status.

  • Hand function assessed via grip strength and a modified Williams Test (Williams Test (M)).

    • Main Results:

    • Demographics explained the majority of variance in grip strength and Williams Test (M) performance.
    • Joint impairment accounted for 7% of the variance in grip strength, independent of demographics.
    • Upper joint impairment and grip strength explained 3% and 5% of the variance in the Williams Test (M), respectively.

    Conclusions:

    • While demographics are primary drivers, joint impairment is a significant correlate of diminished grip strength in the elderly.
    • Reduced grip strength is directly associated with poorer performance on the Williams Test (M).
    • Findings highlight the importance of addressing musculoskeletal health for maintaining hand function in older adults.
