Efficacy of a multicomponent singing intervention on communication and psychosocial functioning in chronic aphasia: a randomized controlled crossover trial

The role of an inpatient aphasia-friendly choir for people with post-stroke communication impairment from the perspective of the multidisciplinary team: An exploratory study

BACKGROUND

There is a growing body of evidence showing the value of community singing-based rehabilitation on psychosocial well-being and communication for people with post-stroke communication impairment (PSCI). However, there has been little consideration of the potential value an inpatient aphasia-friendly choir may have through the perspective of the stroke multidisciplinary team (MDT).

AIMS

To explore the experiences and views of the MDT on the role an established inpatient aphasia-friendly choir, at a stroke rehabilitation centre in South Wales, UK, may play in the rehabilitation of people with PSCI.

METHODS & PROCEDURES

Eight participants were recruited from the stroke rehabilitation centre's MDT. Semi-structured interviews were conducted and the verbatim transcripts were analysed using thematic analysis according to Braun and Clark's work of 2006.

OUTCOMES & RESULTS

Four main themes were identified: (1) breaking down social isolation barriers; (2) patient voice and patient choice; (3) collective well-being and engagement; and (4) the therapeutic benefits across the MDT. The experiences and perceptions overlap, highlighting the wide-reaching therapeutic benefits of singing collaboratively.

CONCLUSIONS & IMPLICATIONS

This research enables us to discover more about how the inpatient aphasia-friendly choir may enhance an individual's well-being, communication and confidence, and their overall rehabilitation from the MDT's perspective. By increasing our understanding of which aspects of the aphasia-friendly choir are most valued, future choir sessions can be better tailored to patients' needs. Additionally, the findings presented here could be taken forward and included in future speech and language therapy interventions, leading to increased patient ownership, not only of the choir but also of their other therapy goals.

WHAT THIS PAPER ADDS

What is already known on this subject Previous research suggests positive implications for therapeutic collaborative singing on psychosocial well-being and communication for people with PSCI. There has been little consideration of the potential value an inpatient aphasia-friendly choir may have through the lens of the stroke MDT. The aim of this research was to explore the experiences and views of the MDT on the role an established inpatient aphasia-friendly choir may play in the rehabilitation of people with PSCI. What this paper adds to the existing knowledge This research highlights the benefits of an inpatient aphasia-friendly choir for an individual's well-being, communication and confidence. An increased understanding enables future choir sessions to be better tailored to patients' needs. What are the potential or actual clinical implications of this work? Participating in the choir was felt to offer an increased opportunity for functional therapy goals in an inpatient setting. The MDT frequently discussed the choir's ability to 'normalise' therapeutic approaches for the patients. A greater understanding of the choir participants empowers therapists to personalise therapy plans further, facilitating effectiveness, efficiency and holistic practice.

Neurologic music therapy for non-fluent aphasia: a systematic review and meta-analysis of randomized controlled trials

Introduction

The efficacy of neurologic music therapy (NMT) techniques for the treatment of non-fluent aphasia has been widely accepted by the rehabilitation medical community. However, consensus on which dimensions of speech function can be improved by NMT techniques and standardized intervention dosage remains elusive. This study aimed to provide evidence regarding the efficacy of NMT in improving speech function and explore the optimal intervention dose. A systematic review and meta-analysis were conducted to search for randomized clinical trials and open-label trials that evaluated speech functions after NMT.

Methods

We searched all papers and reviews published from database inception to July 2023, including PubMed, Cochrane Library, Web of Science, Embase, and CNKI. Statistical analyses were mainly carried out on RevManV5.4.1 and pooled using a random-effects model. The primary outcome was the standardized mean difference (SMD) in speech functions, determined by calculating the change in speech functions score from baseline to the primary endpoint in the NMT group versus the control arm.

Results

A total of 11 studies with 329 patients were included. NMT had a positive effect on repetition ability (SMD = 0.37, 95%CI [0.12, 0.62], p  < 0.05), but did not lead to significant differences in naming, comprehension, spontaneous speech, or communication. When the intervention time was >20 h, NMT exhibited a significant advantage at improving repetition ability (SMD = 0.43, 95%CI [0.06, 0.79], p  < 0.05).

Discussion

This study provides evidence supporting the NMT enhancement of repetition ability in patients with non-fluent aphasia. Future large-sample studies are required to determine the optimal intervention dose of music therapy for different subtypes of non-fluent aphasia.

Structural Neuroplasticity Effects of Singing in Chronic Aphasia

Singing-based treatments of aphasia can improve language outcomes, but the neural benefits of group-based singing in aphasia are unknown. Here, we set out to determine the structural neuroplasticity changes underpinning group-based singing-induced treatment effects in chronic aphasia. Twenty-eight patients with at least mild nonfluent poststroke aphasia were randomized into two groups that received a 4-month multicomponent singing intervention (singing group) or standard care (control group). High-resolution T1 images and multishell diffusion-weighted MRI data were collected in two time points (baseline/5 months). Structural gray matter (GM) and white matter (WM) neuroplasticity changes were assessed using language network region of interest-based voxel-based morphometry (VBM) and quantitative anisotropy-based connectometry, and their associations to improved language outcomes (Western Aphasia Battery Naming and Repetition) were evaluated. Connectometry analyses showed that the singing group enhanced structural WM connectivity in the left arcuate fasciculus (AF) and corpus callosum as well as in the frontal aslant tract (FAT), superior longitudinal fasciculus, and corticostriatal tract bilaterally compared with the control group. Moreover, in VBM, the singing group showed GM volume increase in the left inferior frontal cortex (Brodmann area 44) compared with the control group. The neuroplasticity effects in the left BA44, AF, and FAT correlated with improved naming abilities after the intervention. These findings suggest that in the poststroke aphasia group, singing can bring about structural neuroplasticity changes in left frontal language areas and in bilateral language pathways, which underpin treatment-induced improvement in speech production.

ParkinSong Online: Feasibility of Telehealth Delivery and Remote Data Collection for a Therapeutic Group Singing Study in Parkinson's

BACKGROUND

Parkinson's disease can negatively affect vocal functioning and social wellbeing, particularly in the latter stages of disease progression. Face-to-face group singing interventions can improve communication and wellbeing outcomes, yet not all people can access in-person sessions. To help overcome barriers to participation, exploration of the feasibility and utility of online therapeutic singing programs is needed.

OBJECTIVES

To evaluate the feasibility, acceptability, and preliminary efficacy of a 12-week ParkinSong Online intervention on speech and wellbeing for people with Parkinson's disease.

METHODS

A total of 28 participants with idiopathic Parkinson's disease were recruited to a single-arm feasibility study. Weekly 90-minute online sessions were co-facilitated by a music therapist and speech pathologist. Speech and wellbeing assessments were conducted pre and post intervention. Participant and facilitator surveys were administered after each session, with focus group interviews at the end of the program.

RESULTS

The recruitment rate was high (90%) with no attrition, adverse events, or safety issues. There was good intervention fidelity, attendance (average 89%), and positive participant experience. Feasibility was good, with technology reported as the main challenge (connecting and navigating Zoom). No improvements were seen in voice measures or wellbeing outcomes in this small trial. The online format used in this study did not provide the same benefits as in-person ParkinSong sessions.

CONCLUSIONS

ParkinSong Online is feasible for recreational purposes and social engagement provided that people have adequate technological knowledge or support. The optimal online delivery format to achieve communication improvements in Parkinson's awaits confirmation.

Clinical study of melodic intonation therapy combined with transcranial direct current stimulation for post-stroke aphasia: a single-blind, randomized controlled trial

Background

Globally, more than 10 million new stroke cases occur annually, of which aphasia accounts for about one-third. Aphasia has become an independent predictor of functional dependence and death for the stroke population. The closed-loop rehabilitation of combining behavioral therapy with central nerve stimulation seems to be the research trend of post-stroke aphasia (PSA) due to its advantages in improving linguistic deficits.

Objective

To verify the clinical efficacy of a closed-loop rehabilitation program combining melodic intonation therapy (MIT) with transcranial direct current stimulation (tDCS) for PSA.

Methods

This was a single-center, assessor-blinded, randomized controlled clinical trial, which screened 179 patients and included 39 PSA subjects, with the registration number ChiCTR2200056393 in China. Demographic and clinical data were documented. The primary outcome was the Western Aphasia Battery (WAB) used to assess language function, and the secondary outcomes included Montreal Cognitive Assessment (MoCA), Fugl-Meyer Assessment (FMA), and Barthel Index (BI) for evaluating cognition, motor, and activities of daily living, respectively. With the computer-generated randomization sequence, subjects were randomly divided into the conventional group (CG), MIT combined with sham stimulation group (SG), and MIT combined with tDCS group (TG). After the three-week intervention, the functional changes in each group were analyzed by the paired sample T-test, and the functional difference between the three groups was analyzed by ANOVA.

Results

There was no statistical difference on the baseline. After the intervention, the WAB's aphasia quotient (WAB-AQ), MoCA, FMA, and BI were statistically different in SG and TG, including all the sub-items in WAB and FMA, while only listening comprehension, FMA, and BI were statistically different in CG. The differences of WAB-AQ, MoCA, and FMA were statistically different among the three groups, but BI was not. The post hoc test results revealed that the changes of WAB-AQ and MoCA in TG were more significant than the others.

Conclusion

MIT combined with tDCS can augment the positive effect on language and cognitive recovery in PSA.
