The Effect of Motor Imagery Ability on Function and Proprioception in Myoelectric Prosthesis Users: Protocol for a Cross-Sectional Study.
Article in JMIR research protocols, 2025. 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
backgroundMotor imagery ability (MIA) is a critical cognitive process that enables the mental simulation of movements, facilitating skill acquisition in the use of myoelectric prostheses and their effective control in individuals who have undergone amputation. Although MIA is essential, its impact on upper extremity function and proprioception in myoelectric prosthesis users remains insufficiently studied.
objectiveThis study aims to evaluate MIA in individuals who have undergone transradial amputation and use myoelectric prostheses, compare it with a healthy control group, and examine its association with upper extremity functionality and proprioception.
methodsThis cross-sectional study will include 15 individuals who have undergone transradial amputation (aged 18-65 y) and 15 age- and sex-matched healthy controls, recruited from prosthetics and orthotics centers in Istanbul, Turkey. Assessments will include MIA, hand mental rotation, upper extremity function, and proprioception. MIA will be measured using the Movement Imagery Questionnaire-3 and the Mental Chronometry Test. Hand mental rotation ability will be assessed via the Orientate mobile app. Upper extremity function will be evaluated using the Box and Block Test; Jebsen-Taylor Hand Function Test; and the Quick Disabilities of the Arm, Shoulder, and Hand questionnaire. Proprioception will be assessed through joint position sense measurements. All data will undergo appropriate statistical analyses.
resultsData collection began following funding from the Scientific and Technological Research Council of Turkey on April 25, 2025. As of November 2025, 8 participants with transradial amputation and 8 healthy controls have been recruited. Assessments are ongoing, and study completion is expected by June 2026.
conclusionsThis study will evaluate MIA in individuals who have undergone transradial amputation and use myoelectric prostheses and explore its relationship with upper extremity function and proprioception. The findings are expected to guide the development of targeted rehabilitation strategies, particularly those incorporating motor imagery-based training for this population.
