Background:
Skin tactile perception may indicate frailty in older adults. Although gait performance is crucial for diagnosing frailty, its association with skin tactile perception has not yet been explored.
Objectives:
To examine the association between skin tactile perception and changes in step length, cadence, and gait speed in middle-aged and older adults.
Design:
A longitudinal study (mean follow-up: 10.8 years) SETTING: Community-based survey PARTICIPANTS: A total of 1,403 middle-aged and older adults (aged 40-79 years, 53.6 % men) from the National Institute for Longevity Sciences-Longitudinal Study of Aging were included in this study. These participants completed the baseline survey (1997-2000) and at least two follow-up surveys (2000-2012), had no history of cerebrovascular disease, rheumatoid arthritis, or Parkinson's disease, and had complete data with no outliers in skin tactile perception measurements.
Measurements:
Skin tactile perception was assessed using a two-point discrimination test. Step length (cm), cadence (steps/min), and gait speed (m/min) were evaluated on an 11-m walkway at a usual speed.
Results:
The mean age of participants was 56.4 years. After full adjustment, mixed-effects models with splines revealed that the association between skin tactile perception and gait parameters varied with age. In adults aged 60 and above, we observed non-linear relationships between skin tactile perception and gait parameters. A consistent inflection point around 10 mm in tactile perception was identified across different age groups and gait parameters.
Conclusions:
Among community-dwelling middle-aged and older Japanese adults, skin tactile perception was associated with changes in gait parameters, particularly in those aged 60 and above. The 10-mm threshold in tactile perception may serve as a critical indicator for predicting changes in gait performance. Skin tactile perception tests may prove clinically useful for screening patients at elevated risk of impaired gait performance.

There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...
