Auditory-motor synchronization and interlimb coordination when walking to metronomes with different tempi and structures: A comparison study of children with and without Developmental Coordination Disorder
No full textBackground: Developmental Coordination Disorder (DCD) is a neurodevelopmental disorder affecting motor coordination, impacting daily-life activities like walking. Accurate sensorimotor interactions are crucial for optimal coordination. Auditory-motor synchronization paradigms allow to examine these interactions with tempo and temporal structure of auditory stimuli potentially influencing synchronization and coordination. Therefore, this study aims to investigate auditory-motor synchronization and interlimb coordination in children with DCD and typically developing children (TDC) during walking. Research question: What is the impact of metronome characteristics (tempo, temporal structure) on auditorymotor synchronization, interlimb coordination and spatiotemporal variability in children with and without DCD during walking to auditory metronomes? Methods: Twenty-one DCD and 22 TDC children walked for three minutes to auditory metronomes with different tempi and temporal structures. Synchronization, interlimb coordination and spatiotemporal variability were analyzed using mixed model analysis. Results: DCD presented lower synchronization consistency, inferior interlimb coordination and higher gait variability (speed, step length) across all tempi and temporal structures. At preferred tempo, both groups demonstrated best synchronization and interlimb coordination. The least synchronization and coordination were observed at lower tempo, with DCD additionally showing diminished tempo matching and increased cadence variability. Discrete structures optimized synchronization accuracy and continuous structures enhanced interlimb coordination accuracy. Conclusion: The study highlights difficulties in auditory-motor synchronization, interlimb coordination and spatiotemporal variability in DCD during walking, which were enlarged at lower tempo. Considering various tempi and temporal structures can enrich walking assessments and protentional interventions for DCD. What this paper adds: This paper contributes to the understanding of auditory-motor synchronization and interlimb coordination in children with Developmental Coordination Disorder (DCD) and typically developing children (TDC) during walking. This study expands previous research by exploring the impact of varied tempi and temporal structures on synchronization and interlimb coordination, which has been a relatively unexplored area in the context of DCD. The key findings suggest that children with DCD exhibit lower synchronization consistency and interlimb coordination compared to their typically developing peers across different tempi and temporal structures. We extend previous findings of tapping literature that optimal synchronization and coordination was present at 0 % tempo. Additionally, worsened performance was found at lower auditory tempi (-10 %) than their preferred walking tempo.M.G. received funding from the Flemish Fund for Scientific Research (FWO Vlaanderen, 11K8622N) and the Special Research Fund of Hasselt University (BOF21INCENT27) to conduct this study within the context of a PhD project.

Walking to music and metronome ticks at high and low tempi in persons with progressive MS: preliminary findings
No full text15-73 journals.sagepub.com/home/msj was judged only quantitatively, that is, impact scores were defined as the amount of additional clinical attention the patient needed because of psychiatric conditions. Results: 57% of an average of 82,5 hospitalized patients suffered at least one psychiatric condition with impact on intensity of care. Personality disorders were most common, followed by cognitive disorders without behavioral problems. By far, cognitive disorders had the highest impact on intensity of care. Conclusion: A brief screening of our MS-hospital population for psychiatric conditions with clinically significant impact on intensity of care showed that these conditions are common and, therefore, should be part of hospitalization policy. Based on both frequency and impact score, cognitive and personality disorders proved to have the highest impact on burden of care. Methodological aspects of this exploratory study are further discussed. Background: Walking dysfunctions are prevalent in persons with MS (PwMS), even more in progressive subtypes. The use of auditory stimuli is feasible in people with mild MS (PwMS) and may maximize rehabilitation outcomes. We investigated if progressive PwMS are able to synchronize gait to beats in music and metronomes during walking and its effects on perceived cognitive and physical fatigue. Methods: Participants walked to music and metronomes at preferred walking cadence (0%),-8%,-4%, +4% and +8%), while synchronization (Resultant Vector Length (RVL)), spatiotemporal gait parameters (cadence, speed, double support and stride length) and self-reported outcomes (concentration to synchronise and fatigue) were measured. To examine adaptability and to adjust for possible auditory processing delays, tempi higher or lower than preferred cadence were included. Results: 10 HC's and 9 progressive PwMS were included (age median = 49.4, EDSS (median = 4.4), gait speed (median = 0.84)

Step to the beat: Auditory-motor coupling during walking to higher and lower tempi with music and metronomes in progressive multiple sclerosis: An observational study
No full textMany persons with multiple sclerosis (MS) are confronted with fatigue and difficulties with walking and even more so in persons with progressive subtypes of MS. Task-oriented training, and more specifically in the form of auditory-motor coupling, where persons are asked to synchronise their steps to beats in music and metronomes, is promising. However, it is currently not known whether persons with progressive MS (PwPMS) can synchronise their steps to beats in music and metronomes and if they can adapt their gait to slower and higher tempi.Fonds Wetenschappelijk Onderzoek (FWO) project obtained by Prof. Peter Feys, grant number G082021N.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
