“…Miller et al, 2011; Sapir, Ramig, & Fox, 2011), with the notion that these changes will enhance participation/quality of life. However, results from the current study and others (Donovan et al, 2008; Dykstra et al, 2015; Miller et al, 2008; Miller et al, 2006) highlight the importance of considering the multifaceted nature of communicative participation in assessment and treatment planning for clients with PD. Participation-driven approaches to assessment and intervention are used more commonly in aphasia and, perhaps, this approach should also be considered when working with clients with PD.…”

“…Standardised beta coefficients indicated that perceived level of speech impairment was the greatest contributor to communicative participation (though it should be noted that these coefficients were not considerably larger than a number of other contributors). Prior research has reported minimal or no relationship between objective measurements of speech intelligibility or vocal intensity and communicative effectiveness in those with PD (Donovan et al, 2008; Dykstra et al, 2015). Considered in relation to the current findings, it appears that an individual’s perception of their speech production may have a greater influence on communicative participation than the results of objective measurement of the adequacy of speech.…”

“…However speech production, and degree of speech impairment, form only one component of the broader communication disorder experienced by people with PD (e.g. Donovan, Kendall, Young, & Rosenbek, 2008; Dykstra, Adams, & Jog, 2015; Miller, Noble, Jones, Allcock, & Burn, 2008; Miller, Noble, Jones, & Burn, 2006). Deficits in high-level complex language function (i.e.…”

Purpose: Communication disorders associated with Parkinson’s disease (PD) often lead to restricted participation in life roles, yet there is a limited understanding of influencing factors and few quantitative measurement tools available. This study aimed to identify variables associated with communicative participation in PD, and to examine the relationship between the Communicative Participation Item Bank (CPIB) and existing health-related quality of life (HRQOL) measures. Method: Self-report data from 378 participants with PD from the United States and New Zealand were analysed. Data included responses to the CPIB, PD Questionnaire-8, sub-scales of the Global Health instrument from the Patient Reported Outcomes Measurement Information System (PROMIS), and additional self-report instruments. Result: Greater perceived speech disorder, lower levels of speech usage, fatigue, cognitive and emotional problems, and swallowing difficulties were associated with lower levels of communicative participation. Participants’ age significantly influenced findings, interacting with country of residence, sex, and speech usage. Scores on the CPIB were moderately correlated with HRQOL measures. Conclusion: Communicative participation in PD is complex and influenced by both demographic and disease-based variables, necessitating a broader view of the communicative experiences of those with PD. Measurement of communicative participation as a separate construct to existing HRQOL measures is recommended.

“…SPL would be expected to change as a result of driving increased amplitude of motor output across the speech mechanism through vocal or articulatory effort. The secondary outcome was a participant‐reported measure of communicative effectiveness (CETI‐M), which has demonstrated significant correlation with intelligibility and voice handicap, with established reliability for PD (see Supporting Information). For both measures, the unit of analysis was change from baseline.…”

Speech treatment in Parkinson's disease: Randomized controlled trial (RCT)

et al. 2018

Background As many as 89% of people with Parkinson's disease (PD) develop speech disorders. Objectives This randomized controlled trial evaluated two speech treatments for PD matched in intensive dosage and high‐effort mode of delivery, differing in subsystem target: voice (respiratory‐laryngeal) versus articulation (orofacial‐articulatory). Methods PD participants were randomized to 1‐month LSVT LOUD (voice), LSVT ARTIC (articulation), or UNTXPD (untreated) groups. Speech clinicians specializing in PD delivered treatment. Primary outcome was sound pressure level (SPL) in reading and spontaneous speech, and secondary outcome was participant‐reported Modified Communication Effectiveness Index (CETI‐M), evaluated at baseline, 1, and 7 months. Healthy controls were matched by age and sex. Results At baseline, the combined PD group (n = 64) was significantly worse than healthy controls (n = 20) for SPL ( P < 0.05) and CETI‐M ( P = 0.0001). At 1 and 7 months, SPL between‐group comparisons showed greater improvements for LSVT LOUD (n = 22) than LSVT ARTIC (n = 20; P < 0.05) and UNTXPD (n = 22; P < 0.05). Sound pressure level differences between LSVT ARTIC and UNTXPD at 1 and 7 months were not significant ( P > 0.05). For CETI‐M, between‐group comparisons showed greater improvements for LSVT LOUD and LSVT ARTIC than UNTXPD at 1 month ( P = 0.02; P = 0.02). At 7 months, CETI‐M between‐group differences were not significant ( P = 0.08). Within‐group CETI‐M improvements for LSVT LOUD were maintained through 7 months ( P = 0.0011). Conclusions LSVT LOUD showed greater improvements than both LSVT ARTIC and UNTXPD for SPL at 1 and 7 months. For CETI‐M, both LSVT LOUD and LSVT ARTIC improved at 1 month relative to UNTXPD. Only LSVT LOUD maintained CETI‐M improvements at 7 months. © 2018 The Authors.

“…Everyday activities, such as conversation, are difficult even when voice or speech changes are mild and do not interfere with speech intelligibility (Miller et al, 2006). Recent literature also suggests that psychosocial variables, such as communicative participation, are a separate and distinct construct from other physiologic and perceptual measures, such as speech intensity, that reflect speech production (Dykstra, Adams, & Jog, 2015).…”

Purpose In this project, we explore the experiences of people who report speech changes associated with Parkinson's disease as they describe taking part in everyday communication situations and report impressions related to speech treatment. Method Twenty-four community-dwelling adults with Parkinson's disease took part in face-to-face, semistructured interviews. Qualitative research methods were used to code and develop themes related to the interviews. Results Two major themes emerged. The first, called “speaking,” included several subthemes: thinking about speaking, weighing value versus effort, feelings associated with speaking, the environmental context of speaking, and the impact of Parkinson's disease on speaking. The second theme involved “treatment experiences” and included subthemes: choosing not to have treatment, the clinician, drills and exercise, and suggestions for change. Conclusions From the perspective of participants with Parkinson's disease, speaking is an activity requiring both physical and cognitive effort that takes place in a social context. Although many report positive experiences with speech treatment, some reported dissatisfaction with speech drills and exercises and a lack of focus on the social aspects of communication. Suggestions for improvement include increased focus on the cognitive demands of speaking and on the psychosocial aspects of communication.
