Intrarater Reliability and Analysis of Learning Effects in the Y Balance Test
2023
While the general reliability of the Y balance test has been previously found to be excellent, earlier reviews highlighted a need for a more consistent methodology between studies. The purpose of this test–retest intrarater reliability study was to assess the intrarater reliability of the YBT using different methodologies regarding normalisation for leg length, number of repetitions, and score calculation. Sixteen healthy adult novice recreational runners aged 18–55 years, both women and men, were reviewed in a laboratory environment. Mean calculated scores, intraclass correlation coefficient, standard error of measurement, and minimal detectable change were calculated and analysed between …
Kognitīvo uzdevumu ietekme uz stājas stabilitāti jauniem un veciem cilvēkiem
2017
Kopsavilkums Palielinoties cilvēka vecumam, palielinās kritienu un traumatisma riski. Tā kā Latvijā, kā arī Eiropā kopumā, palielinās populācijas novecošanās, kritienu un traumatisma riski pieaug, un to samazināšanai ir nepieciešami efektīvi profilaktiski pasākumi, kas uzlabotu īpaši gados veco cilvēku mobilitāti un novērstu kritienus. Pašreiz nav vienotu vadlīniju stājas stabilitātes pārbaužu metodikā un uzlabošanā, tādēļ ir nozīmīgi izprast faktorus, kas var ietekmēt posturālo kontroli. Tādejādi darbā tika izvirzīts mērķis noskaidrot kognitīvo procesu ietekmi uz stājas stabilitāti, kā arī izvērtēt antropometrisko parametru ietekmi uz līdzsvara saglabāšanu. Pētījumā piedalījās 60 izmeklēja…
Etude de l'impact du contrôle postural associé au port de verres prismatiques dans la réduction des troubles cognitifs chez le dyslexique de développ…
2007
But de l’etude L’objectif de ce travail est d’evaluer l’impact des modifications proprioceptives induites par un traitement postural sur les troubles cognitifs d’une population d’enfants souffrant de dyslexie de developpement. Patients et methodes Il a ete constitue un groupe de 20 enfants dyslexiques traites par prismes posturaux, semelles « de posture » et reeducation posturale, et un groupe temoin de 13 enfants dyslexiques portant uniquement des lunettes sans prismes. Tous les enfants etaient de sexe masculin. Lors de leur inclusion dans l’etude (M0) et 6 mois plus tard (M6), tous les participants ont ete evalues par un bilan ophtalmologique et postural et ont recu un examen neuropsychol…
Influencia de la tarea dual y la restricción sensorial sobre el control postural en los adolescentes de 13 a 18 años
2020
El presente proyecto tiene como principal objetivo analizar la influencia de la maduración, de las tareas duales y de la restricción de información sensorial en el control postural de los adolescentes. Para ello se han diseñado tres estudios diferentes con una muestra compuesta por adolescentes de entre 13 a 18 años. En el estudio 1 se pretende analizar las diferencias en la estabilidad postural unipodal en función del sexo y la edad de los adolescentes de 13 a 18 años. Los resultados obtenidos muestran unos valores más elevados en las variables área de la elipse, velocidad media antero-posterior y medio-lateral en los chicos que en las chicas. Además, los adolescentes de 14 años muestran u…
Technical determinants of competitive rifle shooting performance
2018
The purpose of this thesis was to identify technical determinants of elite level air rifle and biathlon standing shooting performance and investigate how these technical determinants are affected by training, competition situation, or intense exercise. Forty international and national level air rifle shooters and 17 biathletes participated in the studies. In air rifle shooting, shooting performance, aiming point trajectory, and postural balance were measured from each shot in a simulated competition series in the training situation and in the actual competition situation. The shooters’ competition results were collected from each measured season. In biathlon, the same shooting technical var…
Asociación entre la flexoextensión del tobillo y el control postural del adulto mayor. Efectos de la terapia manual aplicada para su tratamiento y re…
2019
Introducción: Según se envejece aparecen ciertas limitaciones en el organismo que van a contribuir a que el control postural disminuya y aparezca un mayor riesgo de sufrir una caída. La literatura resalta la importancia de la movilidad articular del tobillo en flexoextensión para garantizar el control postural y reducir el riesgo de caídas del adulto mayor. Sin embargo, el grado de asociación entre estos factores, y el estudio exhaustivo de terapias que recuperen posibles limitaciones, permanecen poco estudiado, siendo necesario continuar con la investigación. Objetivos: Comprobar el grado de asociación existente entre el rango articular en flexoextensión del tobillo y el control postural d…
Long-term strength and balance training prevents mobility decline among community-dwelling people aged 75 and older
2016
High functional capacity of muscle strength and balance in older persons promotes independent mobility and prevents functional decline below the disability threshold. This dissertation explored the effects of strength and balance training (SBT) as part of a multimodal geriatric intervention on physical functioning and health-related factors associated with training participation in a community-dwelling population aged 75 years and over. This study is a part of the Geriatric Multidisciplinary Strategy for the Good Care of the Elderly (GeMS) project conducted from 2004 to 2007 in Kuopio, Finland. Participants were randomized into an intervention (n=339) and control group (n=312). The individu…
Accumulation of sensory difficulties predicts fear of falling in older women
2013
Objectives: To explore whether the accumulation of sensory difficulties predicts fear of falling (FOF), and whether the traits correlate with each other regardless of familial factors. Methods: Self-reported hearing, vision and balance difficulties, and FOF were assessed using structured questionnaires at the baseline and after a 3-year follow-up in 63- to 76-year-old women (n = 434). Results: Among the women without FOF at baseline (n = 245), 41% reported FOF at follow-up. Increasing numbers of sensory difficulties at baseline predicted higher incidence of FOF. The relationship between accumulated sensory difficulties and FOF was not mediated by familial factors. Discussion: The accumulati…
Postural entrainment by vocal effort in singing and speech
2009
This study assesses the interaction of the postural control system and the production of expressive vocal behavior during speech and singing. In particular, we focus on the head, whose motions have been implicated for both postural control and spoken language production. How does head motion behavior simultaneously serve posture control and linguistic communication during vocalization? This study examines the interaction of these two subsystems by measuring the effects of different levels of vocal effort (loudness) on speech and singing. We show that as vocalizations becomes louder the correspondence between measures of head motion and speech acoustics become less complex and better coordin…
Anticipatory Postural Adjustments and kinematic arm features when postural stability is manipulated
2018
International audience; Beyond the classical paradigm that presents the Anticipatory Postural Adjustments (APAs) as a manner to create forces that counteract disturbances arising from the moving segment during a pointing task, there is a controversial discussion about the role APAs to facilitate the movement and perform a task accurately. In addition, arm kinematics features are classically used to infer the content of motor planning for the execution and the control of arm movements, The present study aimed to disentangle the conflicting role of APAs during an arm-pointing task in which the subjects reach a central diode that suddenly turns on, while their postural stability was manipulate…
