tDCS in the Context of Rehabilitation

Rehabilitation is a widely used term, with many definitions. According to the World Health Organization, “Rehabilitation is a set of interventions needed when a person is experiencing or is likely to experience limitations in everyday functioning due to aging or a health condition, including chronic diseases or disorders, injuries or traumas.” In the context of tDCS, it is commonly used to improve/maintain function (motor, sensorial, autonomic, and cognitive), decrease the impact of symptoms (such as pain), with the ultimate goal of improving the quality of life of the patient and the caregiver. tDCS is being studied in the context of rehabilitation for several applications. This investigation has been associated with exponential growth. The growing understanding of the biological mechanisms of the effects of tDCS applied in rehabilitation is contributing to this growth. It is currently understood that tDCS can alter and strengthen spontaneous synaptic activity and inflect plasticity interceded by neurotransmitters on a structural level. Thus, tDCS’s ability to promote broad neuroplasticity emphasizes its promise in the framework of rehabilitation [1].
