Regulation of Somatosensory Temporal Discrimination Threshold Through Motor Training: An EEG and Kinematics Study.
Trial report in CNS neuroscience & therapeutics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
aimsMotor training enhances somatosensory temporal discrimination threshold (STDT), but the distinct neural mechanisms underlying actual execution versus motor imagery remain unclear. This study aimed to compare the effects of ball-rotation training (BRT; actual execution) and visual-guided imagery (VGI; motor imagery) on STDT, kinematic performance, and neurophysiological plasticity in healthy adults.
methodsForty-eight right-handed participants were randomized into four groups: BRT (actual execution), VGI (motor imagery without movement), tactile control (simple gripping), and no-intervention control. Over seven days, participants underwent pre-/post-training assessments including kinematic analysis, STDT measurement, power spectral analysis and somatosensory-evoked potentials (SEPs).
resultsBRT significantly enhanced motor performance (83% score increase vs. 21% in controls, p < 0.001) and movement speed (37% cycle time reduction vs. 12%-16% in others, p < 0.001), with partial transfer to the untrained hand. Both interventions reduced STDT but at distinct locations: BRT selectively improved index finger discrimination (64.02 ms → 43.75 ms, p = 0.007), while VGI enhanced palm sensitivity (73.43 ms → 61.13 ms, p = 0.003). Neurophysiologically, SEPs revealed increased spatial inhibition ratio (SIR) plasticity in both BRT and VGI (p < 0.001), correlating with STDT gains. EEG demonstrated BRT-induced gamma-band power increases in parietal regions and theta-band elevations in prefrontal cortex, whereas VGI modulated delta-band activity in ipsilateral parietal cortex.
conclusionActual execution (BRT) and motor imagery (VGI) enhance STDT through distinct neuroplastic mechanisms: BRT optimizes sensorimotor integration via parietal gamma/prefrontal theta oscillations, while VGI relies on ipsilateral parietal delta modulation. These findings underscore the role of cortical reorganization in motor learning and support tailored rehabilitation strategies for neurological disorders.
