A novel wearable interface based on IMUs for robotic endoscopy.
Article in International journal of computer assisted radiology and surgery, 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
purposeFlexible endoscopic robots hold broad application prospects in gastrointestinal tract surgery. However, the lack of intuitiveness and heterogeneity between the interface and flexible endoscopic robots results in insufficient operational intuitiveness and prolonged surgery time. Developing an agile, high-precision, and intuitive control method for flexible endoscopic robots has become a challenge.
methodsThis work proposed a novel method for estimating upper-limb's pose using inertial measurement units (IMUs) by building the upper-limb kinematic model and estimating the pose using solely angle. Additionally, a tremor filter and safety constraints on workspace and velocity were incorporated. Based on this method, this work proposed a novel wearable interface that isomorphically matches to the upper limb and suitable for controlling flexible endoscopic robots.
resultsThe wearable interface's positioning root mean square error (RMSE) reaches approximately 1% of full scale in each axis. Under the control of the wearable interface, the planar positioning RMSE of the flexible manipulator reached 0.56 mm. In the ex-vivo experiment, 156 mm
conclusionThe wearable interface has been proven effective in performing endoscopic submucosal dissection (ESD) which is particularly suitable for flexible endoscopic robots. The experimental results demonstrate the robustness, intuitive, and clinical potential of the leader-follower control system.
