Quick fabrication of 3D-printed prosthetic sockets with embedded sensors to track limb motion.
Article in Frontiers in rehabilitation sciences, 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
Introduction: A simple time-efficient method to fabricate prosthetic sockets with embedded sensors to track limb motion may facilitate the clinical application of continuously collected quantitative data in prosthetics practice. Methods: A 3D-printed inner structure of the socket shape with debosses on the outside surface to hold sensors was fabricated, the sensors were affixed in place, and the socket was laminated and trimmed. Results: The time to fabricate an embedded sensor socket was 12% less than that required to fabricate a traditional carbon-fiber socket with sensors. The investigational sockets increased in volume slightly, <0.2%, over the course of 4 weeks of take-home use, likely because of compression of the inner structure material during ambulation. Sockets with a vapor-smoothed finish had a significantly lower coefficient of friction (COF) with the liner fabric backing than sockets with a normal surface finish ( Discussion: The speed, quality, and durability of the investigational sockets warrant clinical studies to determine which quantitative limb motion metrics (e.g., pistoning, volume, anterior distal motion) help prosthetists meaningfully enhance their patient care.
