Background: Accessibility implies making public places accessible to every individual, irrespective of his or her disability or special need, ensuring the integration of the wheelchair user into the society and thereby granting them the capability of participating in activities of daily living and ensuring equality in daily life.


Objective: This study was carried out to assess the accessibility of the physical infrastructures (public buildings) in the Kumasi metropolis to wheelchairs after the passage of the Ghanaian Disability Law (Act 716, 2006).


Methods: Eighty-four public buildings housing education facilities, health facilities, ministries, departments and agencies, sports and recreation, religious groups and banks were assessed. The routes, entrances, height of steps, grade of ramps, sinks, entrance to washrooms, toilets, urinals, automated teller machines and tellers’ counters were measured and computed.


Results: Out of a total of 84 buildings assessed, only 34 (40.5%) of the buildings, 52.3% of the entrances and 87.4% of the routes of the buildings were accessible to wheelchair users. A total of 25% (13 out of 52) of the public buildings with more than one floor were fitted with elevators to connect the different levels of floors.


Conclusion: The results of this study show that public buildings in the Kumasi metropolis are not wheelchair accessible. An important observation made during this study was that there is an intention to improve accessibility when buildings are being constructed or renovated, but there are no laid down guidelines as how to make the buildings accessible for wheelchair users.

Background: Because of the adverse environmental conditions present in less-resourced environments (LREs), the World Health Organization (WHO) has recommended that specialised wheelchair test methods may need to be developed to support product quality standards in these environments. A group of experts identified caster test methods as a high priority because of their common failure in LREs, and the insufficiency of existing test methods described in the International Organization for Standardization (ISO) Wheelchair Testing Standards (ISO 7176).


Objectives: To develop and demonstrate the feasibility of a caster system test method.


Method: Background literature and expert opinions were collected to identify existing caster test methods, caster failures common in LREs and environmental conditions present in LREs. Several conceptual designs for the caster testing method were developed, and through an iterative process using expert feedback, a final concept and a design were developed and a prototype was fabricated. Feasibility tests were conducted by testing a series of caster systems from wheelchairs used in LREs, and failure modes were recorded and compared to anecdotal reports about field failures.


Results: The new caster testing system was developed and it provides the flexibility to expose caster systems to typical conditions in LREs. Caster failures such as stem bolt fractures, fork fractures, bearing failures and tire cracking occurred during testing trials and are consistent with field failures.


Conclusion: The new caster test system has the capability to incorporate necessary test factors that degrade caster quality in LREs. Future work includes developing and validating a testing protocol that results in failure modes common during wheelchair use in LRE.

Background: Very little is known on outcome measures for children with spina bifida (SB) in Zambia. If rehabilitation professionals managing children with SB in Zambia and other parts of sub-Saharan Africa are to instigate measuring outcomes routinely, a tool has to be made available. The main objective of this study was to develop an appropriate and culturally sensitive instrument for evaluating the impact of the interventions on children with SB in Zambia.


Methods: A mixed design method was used for the study. Domains were identified retrospectively and confirmation was done through a systematic review study. Items were generated through semi-structured interviews and focus group discussions. Qualitative data were downloaded, translated into English, transcribed verbatim and presented. These were then placed into categories of the main domains of care deductively through the process of manifest content analysis. Descriptive statistics, alpha coefficient and index of content validity were calculated using SPSS.


Results: Self-care, mobility and social function were identified as main domains, while participation and communication were sub-domains. A total of 100 statements were generated and 78 items were selected deductively. An alpha coefficient of 0.98 was computed and experts judged the items.


Conclusions: The new functional measure with an acceptable level of content validity titled Zambia Spina Bifida Functional Measure (ZSBFM) was developed. It was designed to evaluate effectiveness of interventions given to children with SB from the age of 6 months to 5 years. Psychometric properties of reliability and construct validity were tested and are reported in another study.

A new way to measure child functioning

UNICEF
WASHINGTON GROUP
May 2017

Expand view

"In recognizing the need for a set of questions that would produce internationally comparable data on children, the Washington Group formed a subgroup in 2009 that is chaired by the National Statistical Office of Italy (ISTAT). UNICEF joined the subgroup in 2011.

The first main activity of the subgroup was the development of a short set of questions to reflect current thinking on child functioning for inclusion in censuses and surveys. The new module uses the ICF-CY as the conceptual framework and relies on a functional approach to measuring disability.

The Washington Group/UNICEF Module on Child Functioning, finalized in 2016, covers children between 2 and 17 years of age and assesses functional difficulties in different domains including hearing, vision, communication/comprehension, learning, mobility and emotions. To better reflect the degree of functional difficulty, each area is assessed against a rating scale. The purpose is to identify the subpopulation of children who are at greater risk than other children of the same age or who are experiencing limited participation in an unaccommodating environment. The set of questions is intended for use in national household surveys and censuses"

The module is being translated into multiple languages. Supporting documentation, including a concept note, tabulation plan, templates for reporting, guidelines for interviewers and training materials are also available.

Progress Report on the implementation of the European Disability Strategy (2010-2020)

EUROPEAN COMMISSION
February 2017

Expand view

The Strategy is the main instrument to support the EU's implementation of the UN Convention on the Rights of Persons with Disabilities (UNCRPD). Progress in all eight areas of the strategy is reported: accessibility, participation, equality, employment, education and training, social protection, health and external action. Initiatives such as the Directive on Web Accessibility, the proposal for a European Accessibility Act, the EU Disability Card project (being piloted in 8 Member States) and provisions in the Erasmus+ programme (allowing better mobility for students with disabilities) are highlighted. 

 

This report presents progress achieved in the first five years of the Strategy and assesses implementation. Many stakeholders have contributed to this work. The United Nations reviewed how the EU has been implementing its obligations under the UNCRPD3, and issued Concluding Observations with concrete recommendations for follow-up. These contain guidance on priority issues while also highlighting the steps already taken (see Annex 3). The European Parliament and the European Economic and Social Committee subsequently prepared their own reports on the implementation of the UNCRPD, while civil society organisations provided analysis and proposals (see Annex 4). The Commission also launched a public consultation to collect views from a broad range of stakeholders on the current situation of persons with disabilities and the impact of the Strategy so far, gathering more than 1,500 contributions (see Annex 1). This report also looks at the role of the supporting instruments and at the implementation of the UNCRPD within the EU institutions. Finally, it looks ahead at how the Strategy will continue to deliver on its objectives. In addition, the report includes a comprehensive and up-to-date overview of EU legal acts with an impact on disability matters (Annex 5)

Purpose: Social inclusion of children with physical disabilities is essential for their mental health. The long-standing conflict and political instability in Palestine since 1948 has resulted in an unprecedented number of children with disabilities. This study aimed to assess social inclusion and mental health of children with physical disabilities in Palestine.

 

Method: A mixed methods research design was used. The 12-item General Health Questionnaire and a Social Inclusion Questionnaire were administered to 100 children with amputations, 12-18 years of age, in the Gaza Strip. Ten semi-structured interviews were also conducted with personnel working across civil society rehabilitation services in the area, particularly in services that focussed on the physical rehabilitation of children who had lost a limb.

 

Results: Quantitative findings indicated that 88% of children’s disabilities were caused by war-related incidents. While the sample of children showed on average relatively low levels of psychological distress, males reported feeling more socially included and having better mental health than did females. Furthermore, there was a strong positive correlation between mental health and social inclusion, and a moderate positive correlation between psychological distress and social inclusion. The qualitative data identified different factors that hinder social inclusion, mainly: political instability; under-resourced disability organisations; lack of coordinated efforts; and negative societal attitudes towards disability.

 

Conclusion: A new questionnaire for social inclusion was developed, which can now be used as a tool to assess social inclusion in similar contexts; as well as a culturally-adapted form of the General Health Questionnaire-12 to assess mental health. There is a clear need for service-providers to move beyond a medical model of care to one that embraces community-based rehabilitation and the realisation of rights, in order to promote the social inclusion and mental health of children with disabilities in Palestinian society.

Purpose: Individuals with tetraplegia depend on alternative interfaces in order to control computers and other electronic equipment. Current interfaces are often limited in the number of available control commands, and may compromise the social identity of an individual due to their undesirable appearance. The purpose of this study was to implement an alternative computer interface, which was fully embedded into the oral cavity and which provided multiple control commands.

 

Methods: The development of a wireless, intraoral, inductive tongue computer was described. The interface encompassed a 10-key keypad area and a mouse pad area. This system was embedded wirelessly into the oral cavity of the user. The functionality of the system was demonstrated in two tetraplegic individuals and two able-bodied individuals

 

Results: The system was invisible during use and allowed the user to type on a computer using either the keypad area or the mouse pad. The maximal typing rate was 1.8 s for repetitively typing a correct character with the keypad area and 1.4 s for repetitively typing a correct character with the mouse pad area.

 

Conclusion: The results suggest that this inductive tongue computer interface provides an esthetically acceptable and functionally efficient environmental control for a severely disabled user.

Long-term training with a brain-machine interface-based gait protocol induces partial neurological recovery in paraplegic patients.

NICOLELIS, Miguel

"Brain-machine interfaces (BMIs) provide a new assistive strategy aimed at restoring mobility in severely paralyzed patients. Yet, no study in animals or in human subjects has indicated that long-term BMI training could induce any type of clinical recovery. Eight chronic (3–13 years) spinal cord injury (SCI) paraplegics were subjected to long-term training (12 months) with a multi-stage BMI-based gait neurorehabilitation paradigm aimed at restoring locomotion. This paradigm combined intense immersive virtual reality training, enriched visual-tactile feedback, and walking with two EEG-controlled robotic actuators, including a custom-designed lower limb exoskeleton capable of delivering tactile feedback to subjects. Following 12 months of training with this paradigm, all eight patients experienced neurological improvements in somatic sensation (pain localization, fine/crude touch, and proprioceptive sensing) in multiple dermatomes. Patients also regained voluntary motor control in key muscles below the SCI level, as measured by EMGs, resulting in marked improvement in their walking index. As a result, 50% of these patients were upgraded to an incomplete paraplegia classification. Neurological recovery was paralleled by the reemergence of lower limb motor imagery at cortical level". It is hypothesised that this unprecedented neurological recovery results from both cortical and spinal cord plasticity triggered by long-term BMI usage."

Background: Providing wheelchairs without comprehensive support services might be detrimental to user satisfaction and function.

 

Objectives: This paper compares wheelchair user satisfaction and function before and after implementation of comprehensive wheelchair services, based on the World Health Organization guidelines on wheelchair service provision in less resourced settings, in Zimbabwe.

 

Method: A pre- and post-test study with a qualitative component was done. Quantitative data were collected with the Quebec User Evaluation of Satisfaction with Assistive Technology for adults and children and the ‘Functioning Every day with a Wheelchair Questionnaire’. Data were collected from 55 consecutively sampled wheelchair users, who received a new wheelchair in the study period. Qualitative data were collected through two audio recorded focus groups and two case studies and are presented through narrative examples.

 

Results: The proportion of adult users who were satisfied significantly increased for all wheelchair and service delivery aspects (p = 0.001 - 0.008), except follow-up (p = 0.128). The same was true for children’s post-test ratings on all variables assessed (p = 0.001 - 0.04), except training in the use of the device (p = 0.052). The biggest improvement in satisfaction figures were for comfort needs (44.3%), indoor mobility (43.2%), outdoor mobility (37.2%), safe and efficient, independent operation (33.5%) and transport (31.4%). The qualitative data illustrated user satisfaction with wheelchair features and services.

 

Conclusion: The wheelchair service programme resulted in significant positive changes in user satisfaction with the wheelchair, wheelchair services and function. It is recommended that the Zimbabwean government and partner organisations continue to support and develop wheelchair services along these guidelines.

Background: Within a rights-based paradigm, wheelchairs are essential in the promotion of user autonomy, dignity, freedom, inclusion and participation.

 

Objectives: This paper aimed to describe a group of Zimbabwean wheelchair users’ satisfaction with wheelchairs, wheelchair services and wheelchair function.

 

Method: A mixed method, descriptive study was done. Quantitative data was collected from 94 consecutively sampled wheelchair users, who accessed wheelchair services at 16 clinics in five Zimbabwean provinces between October 2013 and February 2014, using the Quebec User Evaluation of Satisfaction with Assistive Technology for adults and children and Functioning Every day with a Wheelchair questionnaire. Qualitative data were collected through two focus group discussions (22 participants) and two case studies with participants purposively sampled from those who participated in the quantitative phase.

 

Results: More than 60% of participants were dissatisfied with the following wheelchair features: durability (78.6%), weight (75.6%), ease of adjustment (69.1%), effectiveness (69.0%), safety (66.7%), reliability (66.7%), and meeting user needs (60.6%). Similarly, more than 66% of participants were dissatisfied with various services aspects: professional services (69.0%), follow-up (67.0%), and service delivery (68.3%). Although 60% of participants agreed that the wheelchair contributed to specific functions, more than 50% of participants indicated that the features of the wheelchair did not allow in- (53.2%) and outdoor (52.7%) mobility.

 

Conclusion: Findings indicate high levels of dissatisfaction with wheelchair features and services, as well as mobility. It is recommended that policy and minimum service standards which incorporate evidence and good practice guidelines for wheelchair services and management of wheelchair donations are developed for Zimbabwe.

Exploring the impact of wheelchair design on user function in a rural South African setting

Background: Wheelchairs provide mobility that can enhance function and community integration. Function in a wheelchair is influenced by wheelchair design.

 

Objectives: To explore the impact of wheelchair design on user function and the variables that guided wheelchair prescription in the study setting.

 

Method: A mixed-method, descriptive design using convenience sampling was implemented. Quantitative data were collected from 30 wheelchair users using the functioning every day with a Wheelchair Scale and a Wheelchair Specification Checklist. Qualitative data were collected from ten therapists who prescribed wheelchairs to these users, through interviews. The Kruskal-Wallis test was used to identify relationships, and content analysis was undertaken to identify emerging themes in qualitative data.

 

Results: Wheelchairs with urban designs were issued to 25 (83%) participants. Wheelchair size, fit, support and functional features created challenges concerning transport, operating the wheelchair, performing personal tasks, and indoor and outdoor mobility. Users using wheelchairs designed for use in semi-rural environments achieved significantly better scores regarding the appropriateness of the prescribed wheelchair than those using wheelchairs designed for urban use (p = <0.01). Therapists prescribed the basic, four-wheel folding frame design most often because of a lack of funding, lack of assessment, lack of skills and user choice.

 

Conclusion: Issuing urban type wheelchairs to users living in rural settings might have a negative effect on users’ functional outcomes. Comprehensive assessments, further training and research, on long term cost and quality of life implications, regarding provision of a suitable wheelchair versus a cheaper less suitable option is recommended.

Sightsavers, HelpAge International, ADD International and Alzheimer’s Disease International worked together with the Institute of Development Studies (IDS) to bring the perspectives of those who live in poverty or who are highly marginalised into post-2015 policy making. The aim of the research was to understand better the experiences of social, political and economic exclusion of persons with disabilities and older people in Bangladesh from their own perspectives. Two groups (community and NGO) of peer researchers collected 70 stories from poor and/or excluded persons with disabilities and older people from each of the two sites: Bhashantek, an urban slum in Dhaka; and Cox’s Bazar, a rural area in southeast Bangladesh. From the stories collected and analysed in workshops, the peer researchers identified 13 priority areas that affect persons with disabilities and older people: accidents and disasters; livelihoods; access to education; medical treatment; family support; exclusion and mistreatment; superstition; access to services; mobility; marriage; land; rape and sexual abuse; the role of grassroots community-based organisations. Recommendations from the researchers are made in each area. The peer research programme was evaluated and guidelines for its use are provided.

Purpose:

The African Disability Scooter (ADS) was developed for lower limb amputees, to improve mobility and provide access to different terrains. The aim of this study was to test the efficiency of the ADS in Africa over different terrains.

 

Method: 

Eight subjects with a mean age of 12 years participated. Energy expenditure and speed were calculated over different terrains using the ADS, a prosthetic limb, and crutches. Repeated testing was completed on different days to assess learning effect. 

 

Results:

Speed was significantly faster with the ADS on a level surface compared to crutch walking. This difference was maintained when using the scooter on rough terrain. Oxygen cost was halved with the scooter on level ground compared to crutch walking. There were no significant differences in oxygen consumption or heart rate. There were significant differences in oxygen cost and speed between days using the scooter over level ground, suggesting the presence of a learning effect. 

 

Conclusions:

This study demonstrates that the ADS is faster and more energy efficient than crutch walking in young individuals with amputations, and should be considered as an alternative to a prosthesis where this is not available. The presence of a learning effect suggests supervision and training is required when the scooter is first issued.

The Application of ICF-based Functioning Data on Home Environment Adaptation for Persons with Disabilities

Purpose: This study illustrates how the International Classification of Functioning, Disability and Health (ICF) domains and qualifiers could be used to create functioning profiles of persons with disabilities in order to plan environmental changes. The outcome of the interventions can be measured by before-and-after comparisons of these profiles.

 

Method: 33 persons with disabilities (11 each from three provinces), with an average age of 43 years, were interviewed between November 2011 and May 2012. 67% of them were male. The functioning profiles of all the subjects were used as guidelines for home environment adaptations.

 

Results: The data helped to understand the limitations of persons with disabilities and identified the areas that needed enhancement to improve their functioning. Modification lay-outs were provided for all 33 persons with disabilities.

 

Conclusion and Implications: It was demonstrated that the ICF framework could help create functioning profiles to guide modifications in the home environment. Future studies should examine whether ICF can measure actual changes that occur after the modifications.

Purpose:

The aim of this study was to explore the psychosocial impact of standing devices as experienced by users. 

 

Method:

This is the second part of a comprehensive survey in five counties in Sweden where all the subjects with standing devices were invited to participate. The impact of standing devices on functional independence, quality of life and wellbeing was assessed using a questionnaire, Psychosocial Impact of Assistive Devices Scale (PIADS).

 

Results:

The psychosocial impact of the standing devices was perceived as positive. The highest PIADS scores in relation to age were found in the oldest group, aged 65 years and older. The ability to walk and independence in ambulation resulted in higher scores than the use of a wheelchair and/or dependence on others. Those who stood often awarded higher scores in the PIADS questionnaire compared to those who used the device less frequently. When standing was integrated in various activities, its psychosocial impact received high scores. 

 

Conclusion:

The psychosocial impact of standing devices was generally experienced positively. The main results indicated that standing in a standing device had a value and we as professionals should ask the users about the intended purpose of their standing in order to prescribe the optimal device.

Quantitative Exploratory Evaluation of the Frequency, Causes and Consequences of Rehabilitation Wheelchair Breakdowns delivered at a Paediatric Clinic in Mexico

Purpose: The United Nations Convention on the Rights of Persons with Disabilities recognises assistive technology such as wheelchairs (WCs) as a tool for social inclusion for this population. In less resourced settings, organisations lack information about effective models of WC service provision. The goal of this study was to investigate the lifespan of WCs and whether they provided reliable mobility, at one clinic in Mexico.

 

Methods: Caregivers of children, who had requested replacements for their WCs from a clinic in Mexico, were interviewed in Spanish. Among others, the questions pertained to repairs/modifications, adverse events and WC usage characteristics. The owners exchanged their WCs for new ones at the clinic, and the maintenance status of each returned WC was evaluated using the WC Assessment Checklist (WAC).

 

Results: Twenty-three donated WCs, used by children aged 3 to 14 years for an average of 19 months, were evaluated. Brakes (n=18), seat and back-sling upholstery (n=11 and 7 respectively), and armrests (n=14) were the components that failed most frequently. A total of 26 adverse events due to WC failure were reported. Adverse events were significantly associated with poor WAC scores (rs=-0.544, p=0.007).

 

Conclusions: Poor WC reliability, associated with adverse events which could undermine social engagement, indicates the need for a stronger WC and for regular maintenance. For instance, brake failures which were most often associated with adjustment issues, could have been resolved with maintenance, while seat and back-sling upholstery and armrest failures suggest that the WC may not be appropriate for the environment. Future work should investigate the robustness of these WCs using standardised methods (ISO 7176), as well as the impact of maintenance interventions on WC reliability.
