According to a paper by the University of Helsinki, approximately “40 % of stroke survivors experience aphasia, a difficulty to comprehend or produce spoken or written language caused by a cerebrovascular accident.” Previous research has shown that “the ability to sing can be retained even in severe aphasia. However, the use of singing, especially choral singing, in aphasia rehabilitation has not been widely studied,” until now. The study found that the results of using singing as part of rehabilitation were significant enough that the researchers suggest “singing-based group rehabilitation should be utilised in healthcare as part of aphasia rehabilitation.”
