Neurofeedback as supportive therapy after stroke. Case report

BackgroundNew developments and trends in neurophysiology are presented from the point of view of diagnostics and the new technology available. Based on their own experiences and the literature available, the authors have analyzed neurofeedback, a new rehabilitation method which combines elements of psycho- and neurophysiotherapy.ObjectiveTo explore the usefulness of neurofeedback therapy for stroke patients. The progress of a female patient with Broca's aphasia receiving therapy is analyzed, in which neurofeedback was used alongside more traditional rehabilitation methods.MethodsThe report describes the case of a 53-year-old woman following a hemorrhagic stroke in the left hemisphere, with a past myocardial infarction, hypertension and 40-year-long history of cigarette smoking. A number of tests were used to assess the patient's neurological and neuropsychological functioning.ResultsAn increase in the proportion of β waves in the left hemisphere of the brain and an increase in the amplitude of the SMR in the right hemisphere. Δ and τ waves decreased in both amplitude and percentage in the two hemispheres. Also, a reduction in the τ/β to τ/SMR ration was observed. In comparative tests positive results obtained in terms of: concentration, visual perception, categorizing, as well as the regulation of affect and reduction in the aphasia symptoms.ConclusionsPrevious studies suggest that neurofeedback leads to lasting symptom reduction. This needs to be confirmed with tests on larger samples using standardized assessment procedures.
