The goal of this study was to investigate clinically relevant biomechanical conditions relating to the setup and alignment of knee-ankle-foot orthoses and the influence of these conditions on knee extension moments and orthotic stance control during gait. Knee moments were collected using an instrumented gait laboratory and concurrently a load transducer embedded at the knee-ankle-foot orthosis knee joint of four individuals with poliomyelitis. We found that knee extension moments were not typically produced in late stance-phase of gait. Adding a dorsiflexion stop at the orthotic ankle significantly decreased the knee flexion moments in late stance-phase, while slightly flexing the knee in stance-phase had a variable effect. The findings suggest that where users of orthoses have problems initiating swing-phase flexion with stance control orthoses, an ankle dorsiflexion stop may be used to enhance function. Furthermore, the use of stance control knee joints that lock while under flexion may contribute to more inconsistent unlocking of the stance control orthosis during gait.

Higher external peak knee flexion moments during the stance phase suggest that greater demands for support and stability are placed on individuals and their assistive devices when negotiating real-life ground surfaces. Clinical relevance This study demonstrates that walking on irregular surfaces alters the loads placed on knee-ankle-foot orthoses and that the requirements for knee stabilization increase. This has important clinical implications on the design, prescription, and use of such devices given the structural and functional demands placed on them.

This article analyses policy documents and data from interviews with employment and settlement service providers, employers, and government officials to explore the increasing shift of Australian refugee settlement policies towards neoliberal imperatives of productivity and self-sufficiency. The responses of service providers shed light on prevalent constructions of refugee subjecthood and related expectations of humanitarian entrants as potential labour market participants. Our analysis highlights the policy rationales that underpin the contemporary design and delivery of refugee settlement support, and draws attention to variations in service providers’ adoption of these rationales. We argue that, while the realignment of refugee settlement support in Australia towards ‘workfare’ is consistent with emergent global narratives of ‘enhancing refugee self-reliance’, the significance of this shift lies in the ideologically driven erosion of the primary protective purpose of Australia’s long-standing humanitarian migration programme.

This article draws upon content analysis of Australian parliamentary transcripts to examine debates about asylum seekers who arrived by boat in three historical periods: 1977–1979, 1999–2001, and 2011–2013. We analyze term frequency and co-occurrence to identify patterns in specific usage of the phrase “boat people.” We then identify how the term is variously deployed in Parliament and discuss the relationship between these uses and government policy and practice. We conclude that forms of “discursive bordering” have amplified representations of asylum seekers as security threats to be controlled within and outside Australia’s sovereign territory. The scope of policy or legislative responses to boat arrivals is limited by a poverty of political language, thus corroborating recent conceptual arguments about the securitization and extra-territorialization of the contemporary border.
