Do ankle braces provide similar effects on ankle biomechanical variables in subjects with and without chronic ankle instability during landing?

PurposeThe purpose of this study was to examine effects of a sport version of a semi-rigid ankle brace (Element?) and a soft ankle brace (ASO) on ankle biomechanics and ground reaction forces (GRFs) during a drop landing activity in subjects with chronic ankle instability (CAI) compared to healthy subjects with no history of CAI.MethodsTen healthy subjects and 10 subjects who had multiple ankle sprains participated in the study as the control and unstable subjects, respectively. The CAI subjects were age, body mass index and gender matched with the control subjects. The arch index and ankle functions of the subjects were measured in a subject screening session. During the biomechanical test session, participants performed five trials of drop landing from 0.6 m, wearing no brace (NB), Element? brace and ASO brace. Simultaneous recording of three-dimensional kinematic (240 Hz) and GRF (1200 Hz) data were performed.ResultsThe CAI subjects had lower ankle functional survey scores. The arch index and deformity results showed greater arch deformity of Element? against a static load than in NB and ASO due to greater initial arch position held by the brace. CAI participants had greater eversion velocity than healthy controls. The ASO brace reduced the first peak vertical GRF whereas Element? increased 2nd peak vertical GRF. Element? brace reduced eversion range of motion (ROM) and peak eversion velocity compared to NB and ASO. In addition, Element? reduced dorsiflexion ROM and increased peak plantarflexion moment compared to NB and ASO.ConclusionResults of static arch measurements and dynamic ankle motion suggest that the restrictions offered by both braces are in part due to more dorsiflexed ankle positions at contact, and higher initial arch position and stiffer ankle for Element?.     

Developing policies for inclusive education: a study of the role of local education authorities

In many parts of the world there is evidence of initiatives aimed at finding ways of creating forms of mainstream schooling that can respond to pupils with disabilities and others seen as having special educational needs (UNESCO 1995). There is also a growing research literature that throws light on how schools and classrooms can be developed in relation to this idea (e.g. Rouse and Florian 1996, Sebba and Sachdev 1997, Thomas et al. 1998, Ainscow 1999, Clark et al. 1999). However, few studies have considered the contributions and roles of local administrative arrangements to such developments, even though there is evidence that these can be highly influential in relation to policy implementation in general (Spillane 1998). Drawing on the evidence of a recent study carried out in England, this paper starts to fill this gap. Specifically, it addresses the question: in what ways do local administrative arrangements bear on attempts to develop more inclusive ways of working in schools? In considering the evidence and arguments presented it is important to recognize that the peculiarities of each national context mean that district level arrangements for the management of education in one country cannot be assumed to be similar to that in other countries. Consequently, transporting conclusions from one situation to another is impossible. Nevertheless, a detailed engagement with the experiences of particular countries can provide a useful basis for reflection on what happens elsewhere. Before considering this specific agenda, however, we summarize certain relevant international trends.     

CSE and the 16+: Teachers' Views

During the interview ‘Mary’ – who had last year been a school pupil and this year is a first‐year undergraduate on the new degree in Education (with Teaching Certificate) – talked at some length, and with considerable feeling, about how her main frustration as a female pupil had been what she saw as her systematic disenfranchisement from influence over the content and process of the schools' curricula which she had pursued over the previous thirteen years. Although she felt that all pupils suffered this lack of influence she was convinced that girls suffered disproportionately. [Some time later in the interview], when talking about the ‘teaching practice’ she had recently completed, ‘Mary’ described how her ‘music and movement’ work had met with ‘loud and disruptive’ reaction from some of the boys in the mixed class of 7–8 year‐olds, even though the majority of the children had clearly enjoyed and been engaged by the scheme she had designed. Faced with this rejection, and experiencing some anxiety about how the teachers and her tutor would assess her potential as a future teacher if she was not seen to be exercising what they would count as ‘good control’ of the class, ‘Mary’ resolved her ‘problem’ by designing an alternative scheme which the few boys would not (and did not) reject. Although the girls had ‘subsequently shown less interest’, their quiet acquiescence to what she offered them reduced her anxiety about her assessment as a teacher. When she related her pupil experience to her teaching practice experience ‘Mary’ was dismayed to realise that she had ‘reproduced for others precisely that frustration which [she herself] had experienced as a pupil’.

Leadership for inclusion: a comparison of international practices

The issue of inclusion is high on the educational reform agenda in many countries. Set within the context of the United Nations organisation's push for ‘Education for All’, the aim is to find ways of increasing the participation and learning of pupils who are vulnerable to marginalisation within existing educational arrangements ( World Education Forum, 2000 ). In the United States, inclusive education is generally thought of as an approach to serving children with disabilities within general education settings. Internationally, however, it is sometimes seen more broadly as a reform that supports and welcomes diversity among all learners ( Ainscow, 1999 ). The research reported in this paper adopts this broadened formulation. It presumes that the aim of inclusive education is to eliminate social exclusion and that is a consequence of attitudes and responses to diversity in race, social class, ethnicity, religion, gender and ability ( Vitello & Mithaug, 1998 ). Children with disabilities and others seen as having special educational needs are part of this agenda. The paper focuses specifically on the implications of these developments for leadership roles in schools. In particular, it uses evidence from case studies of leadership practice in three countries to address the question, what types of leadership practice foster inclusion in schools? The paper provides a theoretical framework that throws light on what is involved in such practices and presents illustrative examples. The aim is to provide an analysis that will be of direct relevance to practitioners, whilst at the same time adding to theory. The examples of leadership that are examined were found in schools in England, Portugal, and the United States that serve culturally and linguistically diverse groups of children, including significant numbers from low‐income families. In each of the schools, children with disabilities and others categorised as having special educational needs are taught in general education classrooms alongside their peers.     

Validity extension of the Course-Faculty Instrument (CFI)

The Course-Faculty Instrument (CFI) demonstrates similar measurement properties with student populations at four diverse institutions. These students agree about the nature and extent to which course and instructor attributes relate to their learning. The results suggest that: (1) a perceived learning criterion may have general relevance to students, and (2) validity extension research is an economically feasible alternative to full-scale instrument development and validation efforts. Since validity extension is practical and facilitates cross-institutional comparisons, it appears to be a more viable strategy for researching and instituting student evaluation systems than is suggested by its current usage.     

Developing inclusive education systems: what are the levers for change?

This paper argues that inclusion is the major challenge facing educational systems around the world. Reflecting on evidence from a programme of research carried out over the last 10 years, it provides a framework for determining levers that can help to ease systems in a more inclusive direction. The focus is on factors within schools that influence the development of thinking and practice, as well as wider contextual factors that may constrain such developments. It is argued that many of the barriers experienced by learners arise from existing ways of thinking. Consequently, strategies for developing inclusive practices have to involve interruptions to thinking in order to encourage an exploration of overlooked possibilities for moving practice forward.
