Summary
Ankle proprioceptive measures show excellent reliability. Threshold for perception of passive movement effectively differentiates age-related declines in proprioception, particularly in older adults.
Area of Science:
- Biomechanics
- Neuroscience
- Gerontology
Background:
- Ankle proprioception is crucial for balance and motor control.
- Age-related decline in proprioception can increase fall risk.
- Reliable and valid measures are needed to assess ankle proprioception across age groups.
Purpose of the Study:
- To evaluate the reliability and construct validity of ankle proprioceptive measures.
- To determine if these measures can differentiate proprioceptive abilities among young, middle-aged, and older adults.
Main Methods:
- Assessed test-retest reliability of ankle proprioceptive measures.
- Examined construct validity by comparing measures across three age groups (20-39, 40-59, ≥60 years).
- Measured threshold for perception of passive movement, active position reproduction error, velocity reproduction error, and torque reproduction error.
Main Results:
- Excellent intersession reliability (ICC .79-.95) was found for most measures, with good reliability for plantarflexion torque reproduction (ICC=.72).
- Threshold for perception of passive movement significantly differed between older adults and both younger groups (P<.05).
- Position reproduction error was higher in middle-aged adults compared to young adults (P<.05).
Conclusions:
- Ankle proprioceptive measures demonstrate high reliability.
- Threshold for perception of passive movement is a sensitive indicator of age-related proprioceptive deficits.
- These findings support the use of specific proprioceptive tests for assessing functional changes with aging.
