The Influence of Progressive Speech Rehabilitation Combined with Personalised Noise-Reduced Auditory Scenery on Language Function and Gait Outcomes in Patients with Parkinson's Disease.

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
objectiveThis study aimed to investigate the effects of combining hierarchical speech rehabilitation with personalised noise-reduced auditory scenery on language function and gait outcomes in patients with Parkinson's disease (PD).
methodsThe clinical data of 100 patients with PD admitted to our hospital between January 2021 and December 2023 were retrospectively analysed. Based on the different adjuvant therapy regimens implemented during distinct time periods, patients were divided into the following two groups: the speech rehabilitation group ( n = 52), which received hierarchical speech rehabilitation therapy, and the combined therapy group ( n = 48), which received personalised noise-reduced auditory scenery combined with hierarchical speech rehabilitation therapy. Language function (assessed by the speech item of the Movement Disorder Society Unified Parkinson's Disease Rating Scale Part III [MDS-UPDRS-III] motor examination and the Voice Handicap Index [VHI]) and rehabilitation outcomes (gait parameters [stride length, cadence and gait speed]) were compared between the two groups before and after the adjuvant therapy period.
resultsFollowing the adjuvant therapy period, the combined therapy group exhibited significantly lower scores on the speech item of the MDS-UPDRS-III motor examination and the VHI compared with the speech rehabilitation group ( P < 0.05). Concurrently, the same group demonstrated significantly greater improvements in gait parameters, including stride length, gait speed and cadence ( P < 0.05).
conclusionThis retrospective analysis preliminarily indicates that the combination of hierarchical speech rehabilitation and personalised noise-reduced auditory scenery may yield positive effects on language function and gait parameters in patients with PD. These observations require further validation through prospective, large-sample, randomised controlled trials.
