A novel device for studying temperature and touch interactions.
Article in Journal of neuroscience methods, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundExisting methods to study the effects of skin temperature on mechanical touch perception range from large hot plates, water baths, or bulky, water-controlled thermal contactors which have limited range and resolution. The limited capabilities of these methods prevent the study of thermo-tactile interactions at the finger level in a flexible and precisely controlled manner. NEW
methodHere, we combine small Proportional-Integral-Derivative (PID)-controlled Peltier elements with a calibrated shaker motor for a novel thermo-tactile stimulus delivery system capable of precisely controlling temperature and vibrotactile stimulation to the fingertip. This novel system enables parallel control of mechanical stimulation and thermal stimulation at congruent skin sites of the fingertip. Alternative thermoelectric elements and mechanical actuators could be used in our systems modular configuration.
resultsOur thermo-tactile delivery system can simultaneously deliver precise and stable vibrotactile and thermal stimuli over 30-250 Hz and 20-40°C, respectively, at the fingertip. We validated our system in psychophysical tests and reproduced the established finding that vibration detection thresholds vary according to temperature. COMPARISON WITH EXISTING METHOD(S): Unlike our system, existing methods to study thermo-tactile interactions are restricted to testing skin regions larger than the fingertip or they use tactile probes on the fingertips that are not thermally controlled.
conclusionsOur system represents a novel strategy for combining thermoelectric modules with mechanical actuation to study thermo-tactile interactions at mechanoreceptor-rich fingertips.
