Summary
Age significantly impacts sensory perception. Both vibration and thermal-cooling thresholds in the index finger and great toe increase with age, establishing new normative data for neurological assessments.
Area of Science:
- Neuroscience
- Sensory Physiology
- Gerontology
Context:
- Assessing cutaneous sensory perception is crucial in neurology.
- Age-related changes in tactile and thermal sensitivity are not fully characterized.
- Establishing normative data is essential for diagnosing sensory deficits.
Purpose:
- To evaluate age-related changes in cutaneous vibration and thermal-cooling thresholds.
- To determine normative values for sensory thresholds in healthy individuals across different age groups.
- To provide reference data for detecting abnormal sensory thresholds in clinical and occupational settings.
Summary:
- This study measured vibration and thermal-cooling thresholds on the index finger and great toe in 70 healthy subjects aged 13-83.
- Results showed statistically significant increases in vibration and thermal-cooling thresholds with advancing age.
- 95% confidence limits for predicted threshold values per decade were calculated, offering valuable diagnostic benchmarks.
Impact:
- Provides age-specific normative data for cutaneous vibration and thermal sensitivity.
- Aids in the early detection of sensory impairments in general and occupational neurology.
- Enhances the diagnostic capabilities for neurological conditions affecting sensory pathways.
