Background The World Health Organisation has launched a programme to promote Global Cooperation on Assistive Technology. Its aim is to increase access to high-quality affordable assistive products (AP) for everybody in need. People with intellectual disabilities (ID) are a specific group that could benefit from AP, but use less AP compared to their non-intellectual disabled peers. Method A systematic literature search was carried out to identify barriers and potential facilitators for access to AP for people with ID globally. The search strategy terms were 'Intellectual Disability' and 'Assistive Technology' with the following electronic literature databases PubMed, Embase, ASSIA, Web of Science, Medline, CINAHL complete, PsycInfo, Scopus and ERIC. The quality and relevance of the studies were assessed. Factors associated with access were identified thematically, categorised into barriers and facilitators and mapped into themes.
