“…Alteration of respiratory control per se may contribute to the decrease in MPT, by reducing oral airflow. In fact, faster respiratory rate, less breathing rhythmic patterns, decreased lung volume, apnoea-like periods with decreased arterial blood flow during quiet breathing and monologue have been reported in patients with ID (LaBlance & Rutherford, 1991). Speech intelligibility was also altered significantly in these patients with ID, in relation with the alterations of respiratory dynamics (LaBlance & Rutherford, 1991).…”

Background: Hyperkinetic dysarthria is often present in isolated dystonia (ID) and is still understudied. Four main clusters of deviant speech dimensions in dystonia hyperkinetic dysarthria were initially provided: articulatory inaccuracy, phonatory stenosis, prosodic excess and prosodic insufficiency. Aim: The aim of our exploratory study was to provide preliminary data on both perceptual and acoustic analyses in relation to three out of these four main clusters.Methods & Procedures: Eleven patients with ID and 11 healthy controls (HC) participated in this study. Clinical/perceptual assessments and acoustic analyses of speech recordings were performed, the latter allowing for the analysis of parameters referring to aerophonatory control, voice quality, prosodic features and speech intelligibility estimated by nine listeners. Between-group statistical comparisons were performed (Wilcoxon tests, p < 0.05). Single-case differences between each patient and the control group were also carried out (effect size index and t < 0.05).Outcomes & Results: Between-group comparisons confirmed the presence of a 'phonatory stenosis'; in addition, deficit in aerophonatory control and hypophonia was also displayed. 'Prosodic insufficiency' was confirmed, but not at the individual level. 'Prosodic excess' manifested only in patients with marked and severe dysarthria. Correlations between altered maximum phonation time, loudness variation, speech and articulatory rates on the one hand, and several clinical speech assessments on the other hand, were also found. Conclusions & Implications: From these findings, altogether, perceptual characteristics of hyperkinetic dysarthria, as suggested by Darley et al., were quantified by the acoustic parameters we measured. As regards to our data obtained in a small participant sample, we would suggest that Darley et al.'s clusters of excess and insufficiency prosody should be questioned in future studies involving larger numbers of dystonic patients. Our study provides novel and preliminary results 1204

“…De nouvelles analyses acoustiques sont donc cruciales pour identifier de manière objective les caractéristiques de cette dysarthrie (Kent et al, 1999). Dans ce sens, des études antérieures ont mis en évidence que le débit respiratoire rapide, les moments d'apnée associés à des dysrythmies et la baisse du volume respiratoire définiraient plus spécifiquement la dysarthrie hyperkinétique (LaBlance et Rutherford, 1991). Notre objectif ici est d'approfondir nos connaissances sur la dysarthrie dans la DGP en caractérisant mieux sur le plan acoustique, les paramètres altérés.…”

RESUMELa dystonie généralisée primaire est un trouble neurologique se caractérisant par des mouvements involontaires et une dysarthrie (trouble de la production de la parole) de type hyperkinétique. La classification perceptive des dysarthries de Darley et al., (1969 a, b) montre que dans la DGP, l'altération de l'organisation temporelle de la parole se manifeste par un débit lent, des silences inappropriés et un allongement des pauses. L'objectif de notre étude est de caractériser acoustiquement la parole dans la DGP en vue de confirmer/infirmer ces résultats perceptifs. Globalement, nos résultats ne montrent aucune différence significative entre sujets contrôle et patients atteints de DGP. L'analyse par sujet montre que quatre patients parmi les 11 étudiés présentent cependant une dysrythmie avec au moins une variable temporelle altérée. Alors que la dysarthrie est considérée comme un défaut d'exécution de la parole, il serait intéressant d'explorer l'implication de dysfonctionnements non-moteurs dans l'organisation temporelle de la parole.ABSTRACT Temporal organization of speech in primary generalized dystonia Primary generalized dystonia (PGD) is a neurologic disorder characterized by involuntary movements and associated with a hyperkinetic dysarthria (motor speech disorder). The seminal classification of dysarthrias made by Darley et al., (1969 a, b) denotes that in PGD, the deterioration of speech temporal organization is associated with a slow rate, inappropriate silences and a pause widening. The aim of our study is to describe acoustically speech in PGD in order to confirm (or not) the previous perceptual findings. Globally, our results do not show any significant difference between healthy controls and patients with PGD. The analysis-by-subject demonstrates that 4 patients among the 11 studied however present with a dysrhythmia, with at least one temporal variable altered. While dysarthria is considered a motor speech disorder, it should be interesting to explore the contribution of non-motor dysfunctions in speech temporal organization.

“…For illustration, JRS severity category 3B is defined as “moderate movements or spasms of mouth, jaw, or tongue, interfering with speech, voice, chewing, or swallowing, causing moderate drooling; moderately disabling.” In patients with complex segmental craniocervical dystonia, the UDRS, GRS and JRS are unmistakenly compromised by many of the same problems as the BFM. In addition, none of these scales provide due consideration to dyspnea and involvement of respiratory muscles, including the diaphragm, which may be affected in some patients with dystonia [27–29]. Complaints of dyspnea, often with breathing arrests, are not unusual in patients with craniocervical dystonia [28].…”

Frequently, blepharospasm is associated with involuntary movements of the platysma, lower face and masticatory muscles. Similarly, masticatory dystonia may occur in isolation or in combination with dystonia of other cranial and cervical muscles. The non-possessive and possessive forms of Meige and Brueghel syndromes have been variably and imprecisely ascribed to various anatomical variations of craniocervical dystonia. Herein, the origin of eponymic terms as applied to craniocervical dystonia is reviewed as support for proposed elimination of these eponyms from clinical usage. Although the term "segmental craniocervical dystonia" more accurately captures the combination of blepharospasm and dystonia of other head and neck muscles, delineation of craniocervical subphenotypes is essential for etiological/genetic and treatment studies. To conclude, the clinical features, epidemiology, pathophysiology and therapeutic management of segmental craniocervical dystonia are examined with a particular focus on "blepharospasm-plus" subphenotypes.
