Reliability and validity of a full-body function Get-Up test in older adults

Area of Science:

• Gerontology
• Kinesiology
• Physical Therapy

Background:

• Assessing physical function in older adults is crucial for identifying health risks like sarcopenia.
• Current assessment methods are often costly and require specialized equipment.

Purpose of the Study:

• To evaluate the reliability and validity of a new, inexpensive Get-Up test for assessing physical function in older adults.
• To determine if the Get-Up test can predict sarcopenia prevalence and incidence.

Main Methods:

• 293 healthy older adults performed the Get-Up test twice for familiarization and twice for timed trials on separate days.
• Participants also completed validated clinical tests for strength, function, and fitness.
• Statistical analyses included ANOVA and intraclass correlation to assess reliability and validity.

Main Results:

• The Get-Up test demonstrated strong reliability (intraclass correlation = 0.928).
• The test showed significant negative correlations with measures of strength and function, and a positive correlation with fitness.
• Poor performance was linked to higher sarcopenia prevalence and incidence.

Conclusions:

• The Get-Up test is a reliable and valid tool for assessing full-body physical function in older adults.
• This simple, low-cost test has potential for widespread use in clinical settings and research.
• The Get-Up test may serve as a valuable tool for early identification and monitoring of sarcopenia.
