A rheological study of human cranial cavity in shirodhara procedure using finite element method.
Article in Journal of Ayurveda and integrative medicine. 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
backgroundShirodhara is a classical Ayurvedic therapy involving the continuous pouring of medicated liquids on the forehead to treat stress, insomnia, migraines, and neurological disorders. However, its underlying biomechanical mechanisms remain poorly understood.
objectiveTo simulate and analyze the biomechanical response of cranial tissues during Shirodhara using water, cow milk, and sesame oil, investigate the rheological behavior of the human cranial vault and assess their relative therapeutic efficacy.
methodsA forehead-skull model is developed in ANSYS Workbench to simulate fluid impact under controlled flow conditions. Key parameters such as velocity distribution, pressure gradient, total deformation, shear stress, and von Mises stress are evaluated for each fluid.
resultsSesame oil exhibits the highest velocity (1.13 m/s), pressure gradient (up to 587 Pa), and shear stress due to its greater viscosity and density. This resulted in more pronounced micro-stresses and tissue deformations compared to milk and water.
conclusionSesame oil demonstrated the most effective mechanical interaction with the cranial structure during Shirodhara, which correlates with its well-documented benefits in anxiety reduction, improved sleep, and nervous system regulation.
