Video analysis reveals early signs of Bradykinesia in REM sleep behavior disorder and Parkinson's disease.
Article in NPJ Parkinson's disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Idiopathic REM sleep behavior disorder (iRBD) is a strong predictor of neurodegenerative diseases like Parkinson's disease (PD). Early detection of motor impairments such as bradykinesia is critical for identifying at-risk populations. This study analyzed Finger Tapping Task videos from 66 participants, including healthy controls (HC) and individuals with iRBD and PD. Only videos that received a clinician score of zero on the MDS-UPDRS Part-III finger tapping item were analyzed. Movement amplitude, speed, and their decrements during the task were directly estimated from the videos using machine learning algorithms. Bradykinesia and hypokinesia were detectable in PD but not in iRBD, while decrement in movement amplitude and speed were observed in PD and iRBD. Classification models achieved 81.5% accuracy distinguishing PD from HC, 79.8% distinguishing iRBD from HC, and 81.7% differentiating iRBD from PD. Video-based assessments offer a low-cost, scalable solution for supporting the identification individuals at risk of developing neurodegenerative diseases.
