Summary

The Physical Performance and Mobility Examination (PPME) is a reliable and valid tool for assessing mobility in hospitalized elderly patients. This performance-based instrument accurately measures physical functioning and mobility in frail older adults.

Area of Science:

  • Gerontology
  • Rehabilitation Medicine
  • Clinical Assessment

Background:

  • Hospitalized elderly individuals often experience functional decline and mobility impairments.
  • Accurate assessment of physical functioning and mobility is crucial for effective geriatric care and rehabilitation planning.

Purpose of the Study:

  • To develop and validate the Physical Performance and Mobility Examination (PPME).
  • The PPME is an observer-administered, performance-based instrument designed to assess six key domains of physical functioning and mobility in hospitalized elderly patients.

Main Methods:

  • The PPME was developed with both pass-fail and 3-level scoring systems.
  • Instrument development included training manuals for clinical and research use.
  • Construct validity and interrater reliability were assessed using two patient samples, while test-retest reliability was evaluated in a third sample.

Main Results:

  • The PPME demonstrated high interrater and intrarater reliability for individual tasks and summary scales (Kappas ranging from .75 to 1.0).
  • Test-retest reliability for summary scales was excellent (Kappa coefficients of .99).
  • Construct validity correlations indicated the PPME uniquely measures mobility, distinct from mood or cognitive status, and the 3-level scale showed sensitivity without ceiling or floor effects.

Conclusions:

  • The Physical Performance and Mobility Examination (PPME) is a reliable and valid instrument.
  • It effectively measures physical functioning and mobility in hospitalized and frail elderly populations.
  • The PPME provides a valuable tool for clinical and research settings.
