Distinctive features of bimanual coordination in idiopathic normal pressure hydrocephalus.
Article in Acta neurochirurgica, 2024. 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
backgroundIdiopathic normal pressure hydrocephalus (iNPH) is characterized by cerebrospinal fluid circulation disorders, and presents as gait and balance disturbances similar to those observed in other incurable neurological diseases. Although previous studies have reported deficits in bimanual coordination among patients with iNPH, these potential pathological characteristics have not received much attention to date. This study investigated the temporal characteristics of a bimanual finger-tapping task in patients with iNPH, focusing on within- and between-hand coordination.
methodsStudy participants comprised three groups: patients with iNPH (N = 19, mean age = 76.9 ± 5.6 years), older adults (N = 19, 76.4 ± 5.3 years), and younger adults (N = 13, 32.2 ± 8.5 years). Participants performed a bimanual finger-tapping task under five conditions that manipulated the temporal differences between the two taps.
resultsThe iNPH group exhibited significantly greater errors in both within- and between-hand coordination tasks compared to the other two groups.
conclusionThese results suggest that assessing temporal errors in bimanual coordination tasks, particularly within-hand coordination, may be useful for uncovering pathological characteristics specific to iNPH.
