Feasibility Analysis of a Portable Diaphragmatic Efficiency Monitor for CSCI Patients.
Article in IEEE journal of translational engineering in health and medicine, 2025. 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
objectiveThis study evaluates the feasibility of a noninvasive system for monitoring diaphragmatic efficiency in people with cervical spinal cord injury (CSCI).
methodsTwo versions of a portable hardware system were developed using impedance pneumography (IP) to measure tidal volume (TV) and surface electromyography (sEMG) to assess diaphragm electrical activity (EAdi). Version 1 was used to determine optimal electrode positions, while Version 2 integrated these sensor systems into a compact, portable design. Data from eight healthy male participants were analyzed to assess the correlation and accuracy of TV and respiration rate (RR) prediction using IP and the correlation between sEMG signals and maximum inspiratory pressure (MIP).
resultsFor IP, measurements between the upper sternum and the midclavicular line (MCL) at the 4th intercostal (IC) space showed the highest correlation with true tidal volume. For sEMG, measurements between the mid-sternum and the 6th IC space demonstrated the strongest correlation with MIP. The integrated version 2 hardware demonstrates simultaneous IP and sEMG measurement while dissipating 2.17 mW. DISCUSSION/
conclusionThe proposed system and the results presented may lead to a practical, cost-effective solution for continuous diaphragmatic efficiency monitoring, and thus enabling home-based respiratory care of CSCI patients. Clinical and Translational Impact Statement- This work presents the feasibility of building a wearable system that can unobtrusively monitor diaphragmatic efficiency, and thus enabling noninvasive, cost-effective, and home-based respiratory care for CSCI patients, facilitating early intervention and improved long-term health outcomes. This study is categorized under the early/pre-clinical research category of the NIH Clinical spectrum.
