Biomedical signal processing and rehabilitation engineering: a review

Combining biomedical signal processing and rehabilitation engineering can yield sophisticated and technological designs that will extend the capabilities and improve the quality of life of the disabled person. Information obtained from a biomedical signal, such as electroencephalogram (EEC), can be used to select the appropriate assistive device for the disabled person. In this paper, a thorough review and discussion of state of the art technology in biomedical signal processing and rehabilitation engineering is presented. Various signal processing methods and techniques have been applied to biomedical signals. Towards the end of the paper, challenges and future trends are discussed.
