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.
This 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).
The 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.
Following 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).
This 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.
