The so-called twin-track approach originated in the UK and was then translated into development activities. Organisations working in the field of disability realised that the provision of concrete services to people with disabilities is necessary, yet simply providing mobility aids was not sufficient. Rather, it is only the first step towards empowering people with disabilities. The twin-track approach addresses special needs (e.g. mobility aids), and treats disability as a cross-cutting issue at the same time. It aims at mainstreaming disability into every sector and every development action with the overall goal of increasing the general level of awareness. The approach addresses able-bodied persons as well as people with disabilities; the latter are very often not aware of their rights and perceive themselves according to the medical and charity models (see figure below).
