Effect of Tai Chi Yunshou motor imagery training on upper limb motor dysfunction with stroke patients.
Trial report in BMC complementary medicine and therapies, 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
backgroundUpper limb motor dysfunction is common among stroke patients. Motor imagery, as a non-invasive brain training method, has gained increasing attention and application in stroke rehabilitation. However, there is currently limited research comparing the effectiveness of different motor imagery interventions for upper limb function. This study was designed to compare the effects of Tai Chi Yunshou motor imagery training and upper limb multi-joint linkage motor imagery training in stroke patients.
methodsThis study is an assessor blinding, parallel-design, simple randomized controlled trial. 70 stroke patients who had a recovery period from 2 weeks to 6 months were recruited from a rehabilitative inpatient unit and then were randomly (enrolled from September 25, 2022, to February 1, 2023). Participants were randomized to undergo Tai Chi Yunshou motor imagery training combined with conventional rehabilitation training (n = 35) or upper limb multi-joint linkage motor imagery training combined with conventional rehabilitation training (n = 35). Each group received 6 sessions per week, for 3 weeks. The primary outcome was the Fugl-Meyer Assessment for Upper Extremity at week 3, with higher scores indicating better motor function. The secondary outcomes included the Brunnstrom Assessment, Modified Barthel Index, Modified Ashworth Scale, grip strength, pinch strength, and the Functional Test for the Hemiplegic Upper Extremity (Hong Kong version).
resultsAmong the 70 randomized participants (mean [SD] age, 64.3 [9.2] years), 66 participants (mean [SD] age, 64.5 [8.7] years) completed 3 weeks in the study. At week 3, both groups showed improvement in daily living activities, motor recovery, and upper limb function. The intervention group had a greater decrease in the Fugl-Meyer Assessment for Upper Extremity (10.97 scores) than the control group with a mean difference of 3.88 scores (95% CI, 2.64 to 5.11; P < 0.001).
conclusionsAmong stroke patients in a recovery period, the Tai Chi Yunshou motor imagery training, compared with the upper limb multi-joint linkage motor imagery training, resulted in better motor function after 3 weeks. Further studies are required to explore the underlying mechanisms of the intervention.
