Purpose: 

To investigate the bilateral postural adaptations as a result of standing on an increasingly unstable sway-referenced support surface with both the intact and prosthetic limb for transtibial prosthesis users (TPUs).

 

Method: 

TPUs (n = 14) and matched controls (n = 14) stood quietly in multiple foot placement conditions (intact foot, prosthetic foot and both feet) on a sway-referenced support surface which matched surface rotation to the movement of the centre of pressure (CoP). Force and motion data were collected and used to analyse CoP mean position, displacement integral and force components under intact and prosthetic limbs.

 

Results: 

Significant differences were found between prosthesis users and controls in CoP mean position in anteroposterior (1.5 (95% CI, 1.2–1.8) cm) and mediolateral directions (3.1 (95% CI, 0.5–5.7) cm. CoP displacement integrals were significantly different greater for prosthesis user group in the anteroposterior direction. Force components differences were found in all planes (anteroposterior: 0.6 (95% CI, 0.4–0.8 N); mediolateral: 0.1 (95% CI, 0.0–0.2 N & 0.3 (95% CI, 0.2–0.4) N, inferosuperior: 2.2 (95% CI, 1.4–3.0) N).

 

Conclusions: 

TPUs have bilateral static and dynamic postural adaptations when standing on a sway-referenced support surface that is different to controls, and between prosthetic and intact sides. Results further support evidence highlighting importance of the intact limb in maintenance of postural control in prosthesis users. Differences indicate clinical treatment should be directed towards improving outcomes on the intact side.

Purpose: At least 5% of people in Australia and the USA have cognitive impairment and require support for decision-making. This paper details a research program whereby an evidence-based Support for Decision Making Practice Framework has been developed for those who support people with cognitive disabilities to make their own decisions across life domains.

 

Methods: The La Trobe framework was derived from a research program modeled on the Medical Research Council four-phase approach to development and evaluation of complex interventions. We completed phase one (development) by: (1) systematically reviewing peer-reviewed literature; and (2) undertaking qualitative exploration of the experience of support for decision-making from the perspectives of people with cognitive disabilities and their supporters through seven grounded theory studies. Results of phase two (feasibility and piloting) involving direct support workers and health professionals supported phase three (evaluation) and four (implementation), currently underway.

 

Results: The framework outlines the steps, principles, and strategies involved in support for decision-making. It focuses on understanding the will and preferences of people with cognitive disabilities and guides those who provide support including families, support workers, guardians, and health professionals.

 

Conclusions: This framework applies across diverse contemporary contexts and is the first evidence-based guide to support for decision-making.

Background: The optimal management strategy for multiple sclerosis (MS), and many other chronic diseases, likely involves health behavior modification. Multimodal behavioral interventions may be most effective, but little is known about long-term adherence in people with MS.

 

Methods: This qualitative study assessed barriers and enablers to long-term adherence by people with MS who self-selected for a 5-day health behavior intervention 3–5 years prior. Thirteen women and five men participated in semi-structured phone interviews, which were transcribed and thematically analyzed.

 

Results: The experience was described as useful for information gathering, decision making, and practical strategies regarding health behaviors. The majority still followed supplementation and dietary recommendations most of the time, although consuming non-recommended food while eating out was common. Support at home, ability and enjoyment in food preparation, and ability to resist unhealthy foods were both barriers and enablers. Adherence to “time-consuming” exercise and meditation recommendations were less common and episodic. Many reported competing interests on time from work and family; and barriers including injuries and symptoms, weather, financial or geographical barriers, and lack of person-centred support and motivation. Increased fitness and mobility, weight loss, and a sense of accomplishment and control were advantages and motivators. Practical and attitudinal strategies employed included planning, tailoring activities to ability and preference, and self-monitoring.

 

Conclusion: While most people attempted to engage with all components of the intervention initially, only some still engaged with all components, and none to the recommended levels. These data can inform future quantitative studies and health behavior interventions.

Purpose: This study aims to identify the most important factors that influence the independent bicycle use of visually impaired people in the Netherlands.

 

Materials and methods: Both visually impaired people and professionals participated in a two-round online Delphi study (n = 42). In Round 1 the participants identified the factors which they ranked by relevance in Round 2.

 

Results: The participants prioritised environmental factors related to the traffic situation, the characteristics of the infrastructure, and weather and light conditions (Kendall’s W = 0.66). They indicated that the most influencing personal factors are related to personality, traffic experience, and personal background (W = 0.58). Glaucoma was ranked as the most relevant ophthalmic condition (W = 0.74), while glare was regarded as the most important factor with respect to the visual functions (W = 0.78).

 

Conclusions: The factors provided by this study can be used to optimise the independent cycling mobility of visually impaired people. More research is needed to investigate, both, how and to what extent the mentioned factors influence the cycling behaviour.

The intersection of disability and food security: Perspectives of health and humanitarian aid workers

Background: Most people with disabilities the world over can be found in the Majority (or ‘economically developing’) World. This is also where most of the world’s hungry and malnourished are found. We argue that the intersectionality between disability and nutrition may best be understood through a food security framework, and we position all people living with disability, including those experiencing feeding and swallowing disabilities, as at risk for food insecurity, especially those living in humanitarian emergency contexts.

 

Objectives: This study aimed to explore and describe the knowledge and experience of humanitarian aid workers (HAWs) and health care professionals (HCPs) in food assistance contexts with regard to the nutrition and food security of people living with disabilities.

 

Method: In this exploratory, descriptive study, 16 participants with experience in sub-Saharan Africa and Southern Asia participated in an online survey. Three survey participants with extensive experience were also interviewed. Data analysis involved descriptive statistics and thematic content analysis.

 

Results: Results revealed that participants had generally low levels of exposure to and experience with disability, including swallowing and feeding disorders.

 

Conclusions: Reduced knowledge of HAWs and HCPs regarding disability and the lack of professionals such as speech–language therapists, who manage disability-specific issues such as feeding and swallowing disorders, may affect the food security of people living with disabilities in food assistance contexts.

Background: Workforce factors present a significant barrier to the development of rehabilitation services for people with communication disabilities in sub-Saharan Africa (SSA). Exploring how the work of speech and language therapists (SLTs) in the region is organised and delivered can provide insight into existing services, areas for future workforce development and improved rehabilitation access for people with communication disability.


Objectives: This paper describes the employment and service provision patterns and work roles of a sample of SLTs in SSA.


Method: A broad, purpose-designed, mixed-methods survey was designed to collect data from SLTs living in Anglophone countries of SSA. Descriptive statistics and qualitative content analysis were undertaken. This paper reports on a subset of data from the wider survey.


Results: A description of the employment and work roles of the 33 respondents to the survey and characteristics of their service users is presented. SLTs were commonly employed within private and not-for-profit sectors and frequently worked in temporary jobs. SLTs engaged in a range of work roles, including capacity building and training others. Services were provided by SLTs across age ranges, health conditions and settings, with paediatric, urban services commonly reported. Costs for service users and urban-centred services give indications of barriers to service access.


Conclusion: Knowledge of the way in which speech and language therapy services are organised and provided has the potential to shape the development of communication disability rehabilitation in SSA. This research has identified a range of issues requiring consideration as the profession develops and grows.

Purpose: The study was conducted to examine the relationship between arm and leg motor impairment in stroke survivors and participation restriction, post rehabilitation, within the Tamale metropolis.

 

Method: The participants were 102 stroke survivors from the Tamale metropolitan area, who had undergone at least 3 months of rehabilitation. Upper limb motor assessment was followed by lower limb motor assessment based on the Manual Muscle Test. Levels of participation restriction were measured using the London Handicap Scale. Correlation analysis of motor impairment and participation restriction were done using Spearman rank correlation analysis.

 

Results: The mean age of post-stroke participants was 62.08 years (95% CI= 59.77-64.39), with men comprising 67.65% and 32.35% women. The Spearman rank correlation co-efficient between arm motor impairment and participation was 0.8343, depicting a strong positive relationship between the aforementioned variables. The correlation between leg motor impairment and participation yielded 0.8013. Conversely, leg motor impairment was found to have a stronger relationship with participation restriction in comparison to arm motor impairment.

 

Conclusion and Implications: The strong relationship between limb motor impairment and participation restriction suggests that clinicians and disability experts involved in rehabilitation should take cognisance of the social implication of motor impairment in order to make informed decisions. Further to this, arm and leg assistive devices could be useful in reducing the levels of participation restriction among persons with stroke within the Tamale metropolis.

 

Limitations: A major limitation is that motor impairment was assessed solely on the ability to perform voluntary movement (muscle power). Sensory disturbances and motor coordination difficulties also have the potential to influence participation restriction, so the exclusion of stroke survivors who are unable to communicate implies that external validity of the research is limited.
