Acute Foot Warming Enhances Plantar Tactile Sensitivity With Limited Postural Control Effects in Obese Older Adults.
Article in Physiotherapy research international : the journal for researchers and clinicians in physical therapy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
background and purposeInterventions to enhance tactile sensitivity, such as warming the feet, positively affect skin sensitivity with varying influence on postural control. Here, we hypothesize that foot warming may benefit tactile sensitivity and postural control in older adults, particularly those with obesity.
methodsFifty participants divided into 16 middle-aged adults (14 women, mean ± standard deviation: age 40.29 ± 3.73 years, body mass index, BMI, 24.51 ± 1.70 kg/m
resultsAcute foot warming consistently enhanced plantar tactile sensitivity across adulthood and aging, with the largest improvements observed in obese older adults. In contrast, effects on postural control were limited. DISCUSSION: Consistent with previous studies, we found that foot warming acutely enhances plantar tactile sensitivity across adulthood and aging, with novelty and larger sensory benefits observed in obese older adults. However, improvements in postural control were not identified across different postural tasks. These findings identify foot warming as a simple strategy to acutely enhance plantar sensory function, particularly in older adults with obesity.
