Summary
This study establishes normal posturography values using an inclinometer technique. Postural balance is age-dependent, peaking between 20-60 years, and is accurately assessed with specific testing conditions.
Area of Science:
- Biomechanics
- Neurology
- Gerontology
Context:
- Postural control is crucial for daily activities and is influenced by age and neurological function.
- Standardized posturography measurements are needed to assess balance objectively.
- Inclinometer technique offers a method for quantifying postural sway.
Purpose:
- To determine normative values for postural sway using an inclinometer technique across different age groups.
- To investigate the relationship between postural balance, age, and gender.
- To identify specific posturography conditions that can accurately detect balance impairments.
Summary:
- 167 healthy individuals were assessed using posturography with an inclinometer, measuring average sway angular velocity (omega) under four conditions.
- Results indicated no gender correlation but a significant age-related effect on postural balance, with optimal stability observed between ages 20 and 60.
- While sway direction showed variability, the omega value during eyes-closed stance on an oculo-vestibular platform proved effective in identifying vestibulospinal system dysfunction.
Impact:
- Provides age-specific normative data for posturography, enabling more accurate clinical assessment of balance disorders.
- Highlights the importance of age-matching in interpreting posturography results.
- Suggests a reliable method for distinguishing between normal and abnormal postural control, particularly for vestibulospinal impairments.
