Abstract

Acupuncture is used as a treatment in stroke patients with aphasia, yet the underlying neural mechanisms are unknown. This study aims to examine the relationship between changes in language function and brain activation using functional magnetic resonance imaging in chronic stroke patients with aphasia who underwent an 8-week acupuncture protocol. Seven chronic stroke patients were identified from a stroke database of a regional acute hospital in Hong Kong between January and July 2007. Patients were treated three times a week over a period of 8 weeks. Four acupoints were stimulated on the weak side of the patient's body. No other rehabilitation was given during the study period. Changes in language function were measured by aphasia quotient (AQ) of Cantonese Aphasia Battery (CAB). Functional magnetic resonance imaging blood oxygen level dependent signals were used to demonstrate the correlation between changes in AQ and brain activation after treatment. The patients were divided into well-recovered and poorly- recovered groups based on their CAB scores at entry. The well-recovered group showed significant improvement in CAB scores after receiving acupuncture treatment. A significant correlation between changes in AQ and blood ...Continue Reading
