Current interventional model for movement in Parkinson's disease: network meta-analysis based on the improvement of motor ability.

To identify optimally therapeutic exercise interventions for improving motor ability among patients with Parkinson's disease (PD), we conducted a network meta-analysis (NMA) of randomized controlled trials comparing different exercise regimens. Relevant RCTs were retrieved by searching PubMed, Embase, Cochrane, Web of Science, CINAHL, CBM, China National Knowledge Infrastructure (CNKI), Wan fang, VIP, and other databases from inception to July 9, 2023 is available in English as the primary language. Exercise outcomes as measured by Movement Disorder Society- Unified Parkinson's Disease Rating Scale Part III (MDS-UPDRS-III) score change were evaluated and ranked using STATA software version 18.0. All included studies were assessed for methodological quality using the Cochrane Risk of Bias tool. The final NMA included 71 studies involving 3,732 participants, 87 intervention experiments, and 27distinct interventions. Although most exercise interventions showed some efficacy (reducing MDS-UPDRS-III score), cumulative ranking probability surface (SUCRA) values indicated that the best exercise interventions for motor function improvement were archery (95.6%), riding a bicycle (80.9%), and binary rhythm dance (80.8%). An exercise intervention comprising archery, cycling, and(or) binary rhythm dance may yield superior improvements in motor function among patients with Parkinson's disease.

Porosity and Movement in Life Stories

Fueled by intellectual curiosity, literary discourse oscillates between factual and fictional narratives. Continually nourished by reality and imagination, it reflects a binary rhythm of representativeness and subjectivity. This work analyzes the biographical genre to explore the shift in rhetorical boundaries and representations in self-narratives. It examines various techniques writers use to reclaim the territory of intimate stories and lives. Infusing these narratives with meaning and unity aims to bridge the gap between the individual and the world. Awarding the Nobel Prize for Literature to feminist writer Annie Ernaux highlights the growing interest in the biographical genre. Ernaux, known for placing intimacy at the heart of her work, brings attention to this genre that often navigates through narratives marked by left-wing and 'politically correct' perspectives. Consequently, the genre emerges as a vital participant in the world's progress, establishing self-literature that withstands the test of time. A cross-study of various life stories — including intimate narratives, extremist views, self-portraits, memoirs, autobiographical novels, autofictions, and travel stories — enables us to understand the porosity and movement within this expansive genre. By presenting and juxtaposing different biographies, writers create a space for interaction, allowing the lives of others to permeate our understanding. Consequently, the biographical genre, serving as a mediating force, and the concept of otherness as mediation are reexamined within the fictional landscape of the human mind.

Rhythmic structure in Ausiàs March (1400‒1459) and Vicent Andrés Estellés (1924‒1993): A quantitative constraint-based approach

AbstractA poet’s choice of rhythmic patterns is affected by three factors: a universal set of metrical constraints, common to all languages; the metrical grammar and lexical structure of the poet’s own language; and the poet’s personal style. The first aim of this paper is to analyse how these three factors influence the frequency of different stress patterns in the customary metre of Ausiàs March (1400‒1459): the decasyllable with caesuraa minore(4+6 syllables). The second aim is to compare March’s schemes of stress with the patterns used by Vicent Andrés Estellés (1924‒1993) in his alexandrines in the 1971 bookLlibre de meravelles(Book of Wonders). The comparative analysis shows that the same metrical constraints operate in both authors and that their weight is equivalent. This equivalence can be seen first in the similarity of their arrangement of patterns in terms of frequency, which shows a clear preference for models that are rhythmically better; and second in the similarity of the proportions of their use of different schemes. The twofold coincidence indicates that March and Estellés, in spite of the vast distance in time between them, share the same metrical grammar. All that separates them is March’s slight inclination toward patterns of binary rhythm compared to Estellés’s preference for ternary rhythm. This difference, which is independent of the metre used by the authors, must be attributed to their stylistic preferences.

Dance Rhythms Improve Motor Symptoms in Individuals with Parkinson's Disease: A Randomized Clinical Trial.

Evidence-based practices involving dance modalities found in binary (two-beat rhythm) or quaternary (four-beat rhythm) show that dance positively influences the motor aspects of disease. <br/>Aim: This randomized clinical trial aimed to analyze the effect of two dance rhythm (binary and quaternary) on the balance, gait, and mobility in individuals with Parkinson's disease (PD). <br/>Methods: Thirty-one individuals with PD were randomized into the binary group (n = 18) and the quaternary group (n = 13). Both groups participated in different dance rhythms lasting 12 weeks, twice a week, for 45 minutes. <br/>Results: The binary group showed a significant difference in balance (p = 0.003), freezing of gait (p = 0.007), as well as in the motor aspects of MDS-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), with emphasis on the total values with a score change of 3.23. In the quaternary group, significant differences were found in balance (p = 0.021) with a score change of -2.54 and in the motor aspects of the MDS-UPDRS Part III where the total values stood out with a change of 3.54. <br/>Discussion: When comparing the possible effects of binary and quaternary rhythms on the motor symptoms of individuals with PD, it was demonstrated that binary rhythm improved balance, freezing gait, and UPDRSIII. As for the quaternary rhythm, the benefits were in balance and the UPDRSIII. <br/>Conclusion: The binary and the quaternary rhythm dance protocols positively influenced the motor symptoms of individuals with PD after 12 weeks of intervention.

Effects of binary dance rhythm compared with quaternary dance rhythm in fatigue, sleep, and daily sleepiness of individuals with Parkinson's disease: A randomized clinical trial

Aim: People with Parkinson's disease constantly demonstrate low levels of physical activity, which is why dance has become increasingly important for the treatment of the disease. This study aimed to analyze the influence of binary and quaternary rhythm on fatigue, sleep, and daytime sleepiness in individuals with Parkinson's disease. Methods: 31 individuals participated in this randomized clinical trial with a mean age of 66.6 ± 10.2 years, 71% were male and 29% were female, allocated into two groups, binary and quaternary, where they participated in different dance interventions lasting 12 weeks. A questionnaire was applied including personal and clinical information; Mental State Mini-Examination (MMSE), Hoehn and Yahr (H&Y), Fatigue Severity Scale (FSS), Sleep Scale for Parkinson's Disease (PDSS), and Daytime Sleepiness Epworth Scale (ESS). Results: The groups that participated in binary rhythm classes showed improvement in sleep quality and daytime sleepiness after 12 weeks of intervention. However, no significant differences were found in the group that participated in the quaternary rhythm classes. Moreover, it was noted that the binary group managed to raise the heart rate during the 12 weeks of intervention, given that these results were not obtained in the quaternary group. Conclusion: The results showed the effectiveness of binary rhythm on non-motor symptoms and heart rate increase in individuals with Parkinson's disease. Thus, it is concluded that the binary rhythm was more effective than the quaternary rhythm.

Twirling Triplets: The Qualia of Rotation and Musical Rhythm

While musicologists have long noted that triplet rhythms evoke sensations of rotation in listeners, no theory has been proposed to account for this apparent association. To investigate this phenomenon, 33 excerpts of “spinning, rotating, twirling, or swirling” music were crowd-sourced from an online discussion forum. Analysis revealed a prominence of fast, repeated, isochronous patterns using stepwise pitch movement, with significantly more compound meters than generally found in Western music. Inspired by ecological acoustics, an Ecological Theory of Rotating Sounds (ETRoS) is proposed to explain these associations. The theory maps patterns of loudness fluctuations to trajectories of rotating sound sources. Two experiments tested the theory. In Experiment A, listeners rated how much binary, ternary, quaternary, and quinary figures (of 2–5 notes) evoked sensations of rotation. Experiment B used a two-alternative forced-choice paradigm pitting ecological quaternary stimuli (strong-medium-weak-medium) against unecological stimuli with permuted stress values more typical of Western music (strong-weak-medium-weak). Results indicate that perceived rotation increases with tempo and is poorly evoked by binary rhythms. Loudness patterns consistent with rotating trajectories were perceived as more rotating than unecological patterns—but only when pitch was also moving. Altogether, moderate support is provided for an acoustic-ecological account of rotating sounds.

Metrically conditioned pitch and layered feet in Chugach Alutiiq

This article presents a reanalysis of the foot-based phonology of Chugach Alutiiq (henceforth CA), a language that displays a complex mixed ternary–binary rhythm, as well as metrically conditioned distributions of pitch, fortition and vowel lengthening. Elaborating on earlier analyses of CA that had posited some kind of ternary constituent (Hewitt, 1991, 1992; Leer, 1985a, 1985b, 1985c; Rice, 1992), we propose CA should be analyzed by means of the Internally Layered Ternary (ILT) foot, a minimal recursive foot (Prince, 1980; Selkirk, 1980), which was recently revived in a typological study of binary–ternary stress (Martínez-Paricio &amp; Kager, 2015). It will be argued that ILT feet capture CA’s puzzling dual behavior of unstressed and stressed syllables straightforwardly by referring to the status of syllables as heads or dependents of minimal or non-minimal feet. After showing the value of ILT feet in the analysis of CA rhythmic and segmental patterns, we turn to our analytical focus, the distributions of high and low pitch. This distribution is arguably metrically conditioned, yet an analysis based on stress or standard binary feet cannot capture it, whereas the ILT approach can. To highlight the advantages of our approach, we end by offering brief comparisons with previous analyses of CA.

Speech rhythm and speech rate affect segmentation of reduced function words in continuous speech

Recent work [Dilley and Pitt, Psychol. Sci. (2010)] has demonstrated that reduced function words in speech can perceptually disappear if the rate of surrounding speech is slowed, even when the acoustic properties of the function word (FW) and its immediate phonetic environment are held constant. An experiment was conducted to determine whether this disappearing word effect could be elicited through a manipulation involving speech rhythm, realized as binary and ternary alternations of high and low tones, as well as through manipulations to context speech rate. 74 participants transcribed 32 sentences containing a FW in which the preceding speech within the utterance was resynthesized with a binary or ternary speech rhythm presented at one of three context speech rates. A binary rhythm in the preceding speech context yielded lower FW report rates than the ternary rhythm. These results suggest that listeners’ expectations about speech rhythm and/or syllable grouping affected the number of syllables and words perceived, indicating that such properties may play an important role in word segmentation and lexical access.

Dancing in the Streets: The sensuous manifold as a concept for designing experience

This article builds on the binary rhythms of transparency and reflectivity described by Bolter and Gromala (2003) as being central to the design of interfaces in digital artifacts. It starts from the concept of experience design and suggests that the experience of the interface might better be considered in terms of the ‘sensuous manifold’. The authors present the interactive kinetic light installation, Dancing in the Streets, as an example of how this sensuous manifold could be seen to work in practice. Many participants described this work as being ‘transparent’ and ‘magical’. The article analyses elements of the installation in relation to transparency/reflectivity to assess the reasons behind these descriptions, and to explore how the sensuous manifold experience was achieved for participants. The location of the installation is defined as a ‘non-place’ whose uncanniness contributed to the potential for ambiguity and liminality. The use of light as a medium for urban scenography was also a critical factor in the design of the interface. The images and their behaviour in relation to the participants created the final element of the artwork. The installation was successful in getting the people of York dancing in the streets. In doing so, it foregrounds the concept of the sensuous manifold as a useful concept for experience designers.

Timing and trajectory in rhythm production.

The Wing-Kristofferson movement timing model (A. M. Wing & A. B. Kristofferson, 1973a, 1973b) distinguishes central timer and motor implementation processes. Previous studies have shown that increases in interresponse interval (IRI) variability with mean IRI are due to central timer processes, not motor implementation. The authors examine whether this is true with IRI duration changes in binary rhythm production. Ten participants provided IRI and movement data in bimanual synchronous tapping under equal (isochronous) and alternating (rhythm) interval conditions. Movement trajectory changes were observed with IRI duration (300, 500, or 833 ms) and for 500-ms IRIs produced in rhythm contexts (300/500 ms, 500/833 ms). However, application of the Wing-Kristofferson model showed that duration and context effects on IRI variability were attributable largely to timer processes with relatively little effect on motor processes.

Sedimentation et paleoceanographie du Turonien et du Senonien dans le bassin du Beausset (Var)

Abstract Turonian-Senonian (Cretaceous) sections at a series of localities in the Beausset basin, Var, France, are described, with particular reference to individual cyclothems, with a view to interpreting the depositional history. Transgressive detrital sequences (Angoumian and Coniacian) consisting of vertically or laterally sorted Permo-Triassic material occur at the base of the cyclothems. The sequences are arhythmic or pararhythmic. The upper members show alternations or binary rhythms. Reef cyclothems begin with nodular biogenic limestones and generally end with breccias containing reworked Hippurites sp.
