Development of a physical performance and mobility examination

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.
