Impact of experience and specialization on accuracy and perceived performance of needling techniques in the cubital tunnel: a cadaveric study.
Article in Journal of ultrasound, 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
backgroundInvasive needling procedures in physiotherapy can be performed using palpation or ultrasound guidance. While ultrasound offers greater precision and safety, the influence of healthcare professional experience and specialization in this field on performance has not yet been fully explored. The aim was to compare the accuracy, efficiency, safety, and perceived workload of ultrasound-guided versus palpation-guided needling procedures among physiotherapists with different levels of experience and specialization.
methodsTwenty-seven physiotherapists (students, non-specialized and specialized physiotherapists) performed 20 needling tasks each, on cadaveric specimens, targeting the ulnar nerve in the cubital tunnel. Procedures were conducted under two guidance conditions (ultrasound vs. palpation) and two handling modalities (with or without handpiece). Performance metrics (e.g., distance to target, structures affected) and subjective workload were recorded.
resultsSpecialized physiotherapists demonstrated significantly greater precision, efficiency, and safety than the other groups (p < 0.001). Students and non-specialized professionals had similar performance, particularly in terms of precision and control. Subjective workload was lower in specialists, especially under ultrasound guidance.
conclusionUltrasound guidance improves needling outcomes, especially when performed by trained specialists. General clinical experience without focused ultrasound training may be insufficient to ensure optimal procedural control. These findings support the integration of ultrasound training in advanced physiotherapy programs and the need to seek strategies that enhance learning.
