The influence of upper extremity improvement on daily function in individuals with chronic stroke following task-oriented interventions: a structural equation modeling approach.
Article in Journal of neuroengineering and rehabilitation, 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
backgroundStroke survivors often experience persistent upper extremity (UE) motor impairments, which significantly hinder their ability to perform daily functions. While various components of UE motor abilities—such as impairment severity, muscle strength, and motor function—have been linked to daily living performance, the structural relationships among these factors remain unclear. The objective of this study was to investigate the structural relationships among changes in UE motor impairment, muscle strength, motor function, and daily living activities in individuals with chronic stroke before and after intervention.
methodsThe study included 131 individuals with chronic stroke in outpatient rehabilitation settings. Pretest and posttest measures were used, with the Fugl-Meyer Assessment evaluating UE motor impairment and the Medical Research Council scale measuring muscle strength. Motor function quality and speed were assessed using the Wolf Motor Function Test, while daily living function was gauged with the Nottingham Extended Activities of Daily Living Scale.
resultsModel fitting indices indicated an excellent fit. Results showed that changes in UE motor impairment negatively impacted daily living function (β = −0.188, p = .024) and motor function speed (β = −0.270, p = .001). Changes in muscle strength and motor function quality marginally influenced motor function speed (β = −0.165, p = .055 for each).
conclusionsReductions in UE motor impairment directly diminished improvements in daily living function. Enhancements in muscle strength and motor function quality indirectly promoted these functions through improved motor speed, aiding in the design and monitoring of rehabilitation protocols for stroke patients.
