Postural changes in patients undergoing hyoid surgery for OSAS
2017
The hyoid bone is the only â suspended boneâ in our body, and its suspension system has an important role in posture maintenance. We studied postural modification in a group of patients affected by Obstructive Sleep Apnea Syndromewho had undergone surgical treatment including hyoid suspension. The surgical procedure performed was section of supra- and infrahyoid muscle and mobilization of the hyoid bone through its suspension to the thyroid cartilage. We studied the postural changes with stabilometric tests. In the early post-operative (one week) follow-up, we performed a posturography test with closed eyes and occlusal disjunction, and saw a worsening of the average parameter of the centre…
Alteraciones posturográficas en fases agudas del latigazo cervical
2017
El control postural se logra en términos generales, a partir de la integración de la información proveniente de los sistemas visual, vestibular y propioceptivo a nivel del SNC y de su acción consiguiente sobre los arcos reflejos musculares que desencadena una acción biomecánica. La aparición de la posturografía como técnica cuantitativa para valorar el control postural ofrece muchas posibilidades para valorar patologías que cursan con clínica de inestabilidad. Con estos antecedentes, parecía necesario aprovechar las últimas tecnologías para el estudio del control postural en una patología tan controvertida y desconocida como el síndrome de latigazo cervical. Sabiendo que los pacientes afect…
Relationship between static posturography and gait analysis with the dizziness handicap inventory in vestibular patients
2012
[EN] Objective: The posturography evaluates postural control abnormalities in patients with vestibular disorders. On the other hand, the Dizziness Handicap Inventory (DHI) questionnaire quantifies the impact of these diseases on the patient’s daily life. This paper has aimed to know the relationship between posturography test results and the DHI scores. Material and Methods: A total of 29 subjects with vestibular diseases underwent a static posturography and gait analysis. The system used was NedSVE/IBV. The patients also answered DHI questions. Results: We found a statistically significant positive correlation between static posturography outcomes and physical-functional DHI scores. A stat…
Validity of the Postural Control and Balance for Stroke test.
2007
Background and Purpose. To determine the construct and predictive validity and sensitivity of the sub-scale items for postural changes, sitting balance and standing balance of the Postural Control and Balance for Stroke (PCBS) test over a 90-day follow-up. Method. In the initial phase of stroke the PCBS test scores were compared with values obtained for the Barthel Index (BI) and the four neuropsychological domains most widely studied in the literature: memory; language; visuo-spatial functions; and visual inattention. The ability of the PCBS test at an early stage to predict functional status, as measured by the BI, and tendency to falls at 90 days after stroke was studied. The sensitivity…
Adolescents' postural control learning according to the frequency of knowledge of process
2019
Feedback is one of the most influential factors for motor skills learning. Physical Education teachers commonly use verbal cues to provide knowledge of process (KP) when teaching motor skills, but the ideal presentation frequency for KP in adolescents is unclear. The aim of this study was to compare the effectiveness of the frequency of KP (i.e., 100%, 67%, 0%) on dynamic balance. Thirty adolescents, age 14–15 years, participated in the study. Performance on a stabilometer platform was used to assess dynamic balance. Participants received feedback after each trial (100%), in two out of three trials (67%), or no feedback during 12 30-s trials of practice. Adolescents who received feedback (6…
Expand your body when you look at yourself: The role of the posture in a mirror exposure task
2018
Mirror exposure (ME) is one of the main components of the treatment of patients with eating disorders symptomatology and it has shown its effectiveness in improving several outcomes (e.g., body dissatisfaction). However, the study as to what body posture should be adopted to maximize its effectiveness has been neglected. From embodied cognition and emotion theories, the adoption of an expansive (vs. contractive) body posture has been associated with positive changes in cognitive and emotional responses. The objective of this study was to analyze the effect of adopting an expansive (vs. contractive) posture before an ME task on body-related emotions and cognitions, as well as to analyze the …
Il ruolo del trattamento riabilitativo nei traumi distorsivi dell’articolazione tibio - peroneo - astragalica
2005
Nello studio della traumatologia da sport, interesse meritano le lesioni del collo del piede, dovuta a molteplici e differenti sollecitazioni dinamiche alle quali viene sottopsota l'articolazione tibio- tarsica, in conseguenza del carettere esplosivo dei movimeni in particolari circostanze. Il livello di controllo posturale rappresenta la cartina di tornasole della stabilità funzionale dell'arto inferiore. Per avere articolazioni stabili serve una buona stabilità statica e dinamica, altrimenti avremo come conseguenza alto rischio di lesioni articolari e muscolari, riduzione della potenza esprimibile, gesto tecnico disturbato da movimenti parassiti di compenso, aumento del dispendio energeti…
Postural Control Profiles of Typically Developing Children From 6 to 12 Years old: An Approach Using Self-Organizing Maps
2020
The purposes of the present study were a) to establish postural control profiles for individuals 6–12 years of age, b) to analyze the participants’ characteristics (age, sex, weight, height, and physical activity) in those profiles, and c) to analyze the influence of visual information in the profiles found. Two hundred and eight typically developing children aged 6–12 years performed two trials in bipedal standing position with eyes open and closed. Feature extraction involved time, frequency, and sway-density plot variables using signals from the center of pressure. A Self-Organizing Map was used to classify and visualize the values of the participants in all the postural control variable…
Sustainable service-learning in Physical Education teacher education: examining postural control to promote ASD children’s well-being
2021
As classrooms become more and more diverse, it is imperative to provide physical education teacher education (PETE) students with opportunities to develop competencies that promote quality education for all students. In this study, PETE students applied a physical education servicelearning (SL) program aimed at enhancing Autism Spectrum Disorder (ASD) children’s motor domain and general well-being—objectives that are connected to the third focus of the United Nations’ Sustainable Development Goals (SDGs). Traditionally, research on SL has focused on students’ outcomes, and there is a call to examine SL’s effects on service receivers, which is the gap this paper aspires to fill. The aim of t…
La «fredda» e «allegra» impostura dell’abate Vella nella Palermo settecentesca
2010
Il saggio delinea una geniale impostura che occupò la scena palermitana di fine Settecento seguendo la ricostruzione di uno storico ottocentesco, Domenico Scinà, e la sua riscrittura in un romanzo di Leonardo Sciascia. Un solo protagonista, l’abate Vella, nel testo dello storico; due personaggi, il Vella e il Di Blasi, nel "Consiglio d’Egitto" (1963). Scinà, in uno scritto del 1824, presenta l’abate Vella come un avventuriero e ripercorre l'impostura grazie alla quale egli aveva costruito dal nulla una falsa storia della Sicilia, tutta orientata a rafforzare e ampliare prerogative e diritti della monarchia contro le appropriazioni, ritenute indebite, dei grandi feudatari. Nel romanzo storic…
