Ultrasound Guidance to Augment Needle Electromyography Precision in the Complex Nerve Injury Setting.
Review in Muscle & nerve, 2026. 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
The rise in popularity of nerve transfer surgery in individuals with peripheral nerve and spinal cord injuries has elevated the importance of the preoperative electrodiagnostic examination. Needle electromyography (EMG) provides peripheral nerve surgeons with precise information about donor and recipient muscle health, aiding in decisions regarding surgical options, donor muscle viability, and timing of intervention. However, traditional anatomical landmarks for typical donor and recipient nerve-muscle combinations in nerve transfer surgery are either not well described in the literature or become less dependable in the presence of contracture, spasticity, or muscle atrophy and fibrosis. Ultrasound (US) can be a valuable tool to augment the needle EMG examination. Herein, we describe US approaches to improve the precision of the needle EMG examination for 10 muscles in the upper extremity and two muscles in the lower extremity that are routinely involved as either donors or recipients in nerve transfer surgery. The purpose is to provide a reference guide for the electrodiagnostic medicine specialist in the complex nerve injury setting. This includes information on surrounding anatomical structures for localization and those that should be avoided. Relevant US principles for EMG are discussed including: (1) the advantages and disadvantages of short-axis and long-axis views of the target muscle, emphasizing the predominant use of short-axis for adequate visualization of all surrounding structures and enhancing patient safety, (2) in-plane versus out-of-plane approaches, and (3) enhancing confidence in the precision of the needle EMG via the dynamic capability of US.
