The central nervous system (CNS) controls and coordinates functions of the human body and mind. Damage to the CNS causes several disorders such as cervical spondylosis, stroke, amongst others. These disorders deprive the abilities of a person needed for daily life. Rehabilitation is one of the key components in recovery of these abilities after CNS damage and Well-established and coordinated multidisciplinary efforts by specialized rehabilitation services are needed. However, such services are limited and inadequate in many developing countries. Also, effective rehabilitation requires the involvement of highly trained professionals. Shortage of such experts is also a serious problem in low to middle level income countries. Many individuals with disabilities depend on other people for daily activities. Therefore, researchers have developed many automated rehabilitation systems based on technology to address the lacuna of health care professionals who are trained to assist patients with disabilities. Such systems offer a number of advantages over conventional methods, including a standardized training environment and the ability to increase therapy intensity and dose, while reducing the physical burden on therapists. This paper provides a review of literatures on automated rehabilitation techniques developed for patients with CNS disorders. The literature reviewed in this paper suggests that for successful development of automated rehabilitation, a knowledge about the physiological basis of the recovery of function, employed is essential. A spirit of cooperation between physicians, health care professionals such as physiotherapists, clinical neuro rehabilitation scientists and information technology specialists is also necessary.
