Egocentric mental rotation in individuals with multiple sclerosis: relationship with disability and cognitive parameters.

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
backgroundThis study aims to examine whether egocentric-based mental rotation is affected in individuals with Multiple Sclerosis (MS) and to analyze its relationship with disability, functional system scores (FSS), and cognitive parameters.
methodsThe study involved 57 right-dominant individuals with MS and 40 right dominant healthy subjects. Disability was assessed using the Neurostatus-Expanded Disability Status Scale (Neurostatus-EDSS). Participants' performance on mental rotation tasks was evaluated with the Recognise Hand App™, Recognise Foot App™, measuring reaction times (seconds) and accuracy (%) for hand and foot stimuli. Cognitive functioning was assessed using the Brief International Cognitive Assessment for MS (BICAMS).
resultsMS patients exhibited lower performance in right hand mental rotation reaction time (p = 0.042), right hand accuracy percentage (p < 0.001), right foot accuracy percentage (p = 0.035). Positive correlations were found between disease duration, EDSS total score, cerebellar FSS, bladder-bowel FSS, and ambulation scores with reaction times, while negative correlations were observed with accuracy percentages (p < 0.05). Additionally, a positive correlation was identified between accuracy percentages and BICAMS (p < 0.05).
conclusionsThe study revealed substantial impairments in right-hand and right-foot performance in right dominant individuals with MS. Mental rotation abilities were found to be related to disease duration, higher EDSS and FSS scores, as well as cognitive functioning. Identifying the cognitive domains and functional systems associated with egocentric mental rotation will contribute to better understanding this underexplored area and developing potential treatment strategies to enhance functionality.
