ISPO Consensus Conference on Wheelchairs in Developing Countries: Conclusions and Recommendations

 

 

Wheelchair

Purpose of a wheelchair

•         The fundamental purpose of a wheelchair is to promote mobility, inclusion and enhanced quality of life of the user

 

Definition of a wheelchair

 

•         A mobility device to promote inclusion and participation (WHO definition)

 

•         A technical aid intended to provide wheeled mobility and body support for individuals with impaired mobility to walk (ISO 7176-26: Wheelchairs - Vocabulary, FDIS  2005)

 

•         A device to provide wheeled mobility with a seating support system for a person with a walking limitation (ISO definition modified by the conference)

 

•         It is recommended that ISO revise its definition of a wheelchair in order to take account of the currently accepted terminology

 

Definition of an appropriate wheelchair

•         A wheelchair is appropriate when it meets the individual’s needs and environmental conditions; provides proper fit and postural support based on sound biomechanical principles; is safe and durable; is available and can be accessed, maintained and sustained in the country at the most economical and affordable price.

 

User involvement

•         “It is about the user, not just about the wheelchair”.  Wheelchair users should be involved in all aspects of wheelchair provision.

 

 

Needs

Needs assessment

•         According to WHO it is estimated that about 10% of the population are people with disabilities. Studies also show that about 10%  of people with a disability require a wheelchair

 

•         There is no accurate figure for the number of people in developing countries that require a wheelchair. It is estimated that about 1% in any given population, i.e., about 65 million people worldwide require a wheelchair.

 

•         Anecdotal evidence indicates a very small minority of those in need have access to an appropriate wheelchair.

 

•         More accurate data of the needs are required to be collected in order to be able to address them.

 

•         It is important to develop and implement standardized tools and methodology for data collection.

 

•         The number of people who need wheelchairs is so large that all efforts should contribute towards developing long-term sustainable services.

 

Outcome measures

•         Reliable record keeping is essential for all phases of wheelchair provision including assessment, prescription, fitting, delivery and follow-up.

 

•         Regular follow-up/evaluation of outcomes of wheelchair provision should be performed. 

 

•         User satisfaction surveys must be an integral part of outcome assessment.

 

•         User satisfaction surveys should be performed and include measures of the impact of wheelchair provision on the quality of life of the user.

 

Information sharing

•         There is a lack of shared information about resources, activities and initiatives which may result in a duplication of efforts and gaps in services.  The establishment of a website and/or an accessible database would be of benefit to those involved in wheelchair provision.

 

 

Services

(Note: in this document Wheelchair Services refers the service delivery of wheelchairs to the individual users. Wheelchair Provision refers to the overall subject including design, manufacture distribution and services)

 

•         Wheelchair services are an integral part of wheelchair provision.

 

•         User participation is an integral part of wheelchair services.

 

•         Wheelchair services should be delivered by trained personnel.

 

•         Government has the primary responsibility for sustainable wheelchair service. Wheelchair services should be an integral part of national strategies.

 

•         The wheelchair services are encouraged to ensure that people with disabilities from all sectors of society are provided with appropriate wheelchairs including those from marginalised and vulnerable groups such as women and children.

 

•         The aim of wheelchair services is to ensure that the person in need of a wheelchair receives it together with the necessary information and support. The wheelchair should meet the individual’s needs in terms of mobility, appropriate fit, comfort, safety and ability to carry out activities of daily living and exercise basic human rights.

 

•         The following table was agreed as a first draft of specifying the elements and requirements for wheelchair services:

 

Elements

Requirements

Awareness

 

•         Basic information about needs for and benefits of using wheelchair (e.g. leaflet with information about who needs a wheelchair which is distributed to different organisations based on available services (to avoid expectations that cannot be met))

Products

•         As a minimum, developing countries are encouraged to adopt the wheelchair ISO standards as they exist at present, particularly:

-       ISO 7176 - 8: Wheelchairs - Requirements and test methods for static, impact and fatigue strengths, 1998

-       ISO 7176 - 1: Wheelchairs - Determination of static stability, 1999

-       ISO 7176 - 3: Wheelchairs – Determination of the efficiency of brakes, 2003  

-       ISO 7176 - 5: Wheelchairs – Determination of overall dimensions, mass and turning space, DIS 2005

-       ISO 7176 -15: Wheelchairs - Requirements for information disclosure, documentation and labelling, 1996, and

-       ISO 7176 -16: Wheelchairs - Requirements and test methods for resistance to ignition of upholstered parts, 1997

 

These represent the minimum requirements for wheelchairs provided in these countries.

 

•         Organisations importing wheelchairs are encouraged to ensure that the wheelchairs meet ISO standards or the wheelchair standards existing in that particular country, whichever is higher.

 

•         There is a need to develop more demanding versions of ISO standards to represent the more challenging conditions in developing countries.

 

•         It was recommended that ISO be requested to revise the existing standards to take into account the needs in developing countries.

 

•         Test methods should be designed to replicate usage in the relevant environments (based on an average life expectancy of 5 years).

 

•         It is recommended that a representative sub-committee be identified to propose requirements within each category outlined in the table below:

 

Static stability

Front, lateral, diagonal and backward tipping for least and most stable axle positions.

Effectiveness of brakes

ISO standard with set angle for tipping of chair and angle at which brakes hold, test for sudden release of the brakes.

Strength durability

Stress testing of front casters, structural integrity, peak force or yield failures and double drum (fatigue) test.

Pressure relief cushion (compulsory)

Ratings for cushions, determine levels.

Standard test using indenter, concern about cushion changing centre of gravity, life of cushion, develop test equipment.

Safety

Pinch points and sharp edges, self-locking nuts.

Dynamic stability

Declining ramp with obstruction to cause abrupt stop of wheelchair (testing to assure wheelchair user remains in wheelchair after abrupt stop).

Adjustability

Footrest adjustment range, brake adjustment.

Information about armrest height, backrest height range, range of seat width/depth and fore/aft rear wheel position.

Postural support

All body contact surfaces supporting adequately (e.g. footrests). Wait for ISO standards on postural support devices. Sub-committee will revisit within 6 months and make recommendations.

Quality of manufacture

Durability testing, sample size and frequency for product testing (quality control), sharp edges and points, corrosion resistance, fit and finish.

Availability of components

Manufacturer to ensure availability or provision of needed parts, reporting of any hard-to-find parts/components.

Work towards common components/parts across different manufacturers.

Consumables separate from replacement parts.

Rolling resistance

Resistance to movement over a range of surfaces such as grass, mud and sand.

Reflectors

All wheelchairs should be fitted with robust reflectors on all sides to increase their visibility within traffic.

Other

Tracking, transportability, include note on handrims and wheel size.

 

•         It was further agreed that there would be value in testing current wheelchair designs. Each of the organizations represented at the consensus conference agreed to participate.

 

 

Production

Standards and guidelines

•         All wheelchairs, whether locally produced or imported, and whether made in small, medium or large scale enterprises should meet or exceed ISO standards.

 

User choice

•         Stakeholders are encouraged to recognise the right of wheelchair users to choose their wheelchair and to work in collaboration with the user.

 

•         Users’ needs are best met when there is a variety of wheelchair models from which to choose.

 

Acquiring wheelchairs

•         When determining whether to acquire wheelchairs via import or local production, decision makers are advised to balance a variety of factors.  These include needs of the local population, quality and variety of wheelchair models, purchase price, cost of repair and replacement, effect on local employment and wheelchair production, and national policies and strategies including long-term sustainability.

 

Locally repairable

•         Regardless of scale and location of production, wheelchairs must be locally repairable.

 

 

Distribution

•         There is a vast need for appropriate wheelchairs in developing countries and it is recognised that there are different methods of wheelchair distribution which are not mutually exclusive but can complement each other.

 

 

•         All methods of distribution have a part to play and stakeholders are encouraged to work closely together to ensure that there is no duplication of effort and waste of resources.

 

•         It is recommended  that, irrespective of method of distribution:

-       the provider has the capacity to provide the wheelchairs in a reasonable and responsible manner;

 

-       the distribution is based on an assessment of the situation in the country or the region of the country and considers the impact on local wheelchair producers and service providers;

 

-       procured wheelchairs meet or exceed relevant international standards and be appropriate for the environment of use;

 

-       wheelchairs are provided following a provision process that meets or exceeds internationally agreed minimum requirements for service provision, including requirements for assessment, fitting, user training and follow-up;

 

-       wheelchairs are repairable in the region of the country where they are provided or expected to be used.

 

-       distributors coordinate their distribution with national and local governments as well as producers and providers of wheelchairs in the country; and

 

-       distributors of wheelchairs network with each other.

 

 

Training and education                        

•         It is recognized that training and education are key elements for developing, introducing, maintaining and building sustainable wheelchair services.

 

•         All stakeholders need to be trained and/or informed regarding their roles in wheelchair provision.

 

•         All individuals involved in wheelchair services should be trained. These may include:

–        Physiotherapists

–        Occupational Therapists

–        Doctors

–        Nurses

–        Prosthetists and Orthotists

–        Engineers/Technologists/Technicians

–        CBR personnel

–        DPO/Rights group members

 

•         In particular the user and assistant must be properly informed and trained.

 

•         Comprehensive information should be provided to governments, decision makers, donors and other stakeholders.

 

•         Training and education for stakeholders can be divided into four types:

–        Formal training to establish specialists in wheelchair provision where possible.

 

–        Special modules for other individuals involved in wheelchair provision.

 

–        Comprehensive information for different stakeholders (including government, decision makers and donors)

 

–        structured/formalized peer training for users and assistants.

 

•         Professional profiles for specialists in wheelchair provision should be developed

 

•         An expert group under the umbrella of an internationally recognized organization should:

–        develop the professional profiles for the training of people involved in wheelchair service provision

 

–        specify the content of the various training, education and information modules required

 

 

WHO Guidelines

•         The importance of developing the WHO Guidelines on the provision of manual wheelchairs in less resourced settings is recognized.

 

•         In order that the guidelines be effective as soon as possible, it is recommended that WHO quickly incorporate the outcomes from this consensus conference into the guidelines and share a draft of the revised guidelines with a larger audience for review.
