Rehabilitation assists people with disabilities by reducing impairments and preventing complications to help them achieve optimal functioning. However, there are major gaps and challenges to providing rehabilitation services globally. Many people lack access to rehabilitation due to limited resources, specialists concentrated in cities, and long waiting lists. There is also a shortage of rehabilitation personnel worldwide. To address these issues, policies and health systems need reform, financing must be increased through partnerships, and community-based models should be used to decentralize and expand access to rehabilitation services.
