Summary
This summary is machine-generated.

The Walking While Talking (WWT) test is valid for assessing older adults with lower-limb amputation (LLA). This dual-task test provides normative data and a new scoring system for improved clinical use.

Area of Science:

  • Rehabilitation Science
  • Gerontology
  • Biomechanics

Background:

  • The Walking While Talking (WWT) test, a dual-task (cognitive and motor) assessment, lacks validation in older adults with lower-limb amputation (LLA).
  • The WWT test comprises two sections: WWT-simple (reciting alphabet letters while walking) and WWT-complex (reciting alternating letters while walking).

Purpose of the Study:

  • To validate the WWT test for older adults with LLA.
  • To establish normative data for the WWT test in this population.
  • To introduce a novel, objective scoring system for the WWT test.

Main Methods:

  • Collected baseline cross-sectional data from 56 community-living older adults (≥50 years) with LLA.
  • Recorded time, letters recited, and errors for both WWT sections.
  • Assessed validity by correlating WWT times with the Activities-specific Balance Confidence (ABC) scale and the 2-Minute Walk Test (2MWT) scores.

Main Results:

  • WWT test completion times were negatively correlated with both ABC and 2MWT scores, as hypothesized.
  • Developed WWT scores showed positive correlations with 2MWT scores.
  • This indicates that poorer performance on WWT correlates with poorer balance and walking capacity.

Conclusions:

  • WWT test completion times correlate with established measures of balance (ABC) and walking capacity (2MWT), supporting its validity in older adults with LLA.
  • A new, objective scoring method for the WWT test was developed, aligning with its dual-task nature.
  • The WWT test is a valid tool for assessing older adults with LLA, offering valuable clinical insights.
