Objective To explore the effect of action observation therapy on unilateral spatial neglect after stroke.Methods From March, 2017 to April, 2018, 44 patients with left-sided neglect due to unilateral right-sided vascular brain lesions were randomly divided into control group (n=22) and experimental group (n=22). The control group received the dynamic landscape video observation training, and the experimental group received the action observation training, based on routine rehabilitation, for three weeks. Before treatment, one week and three weeks after treatment, they were evaluated with Chinese Behavioral Inattention Test-Hong Kong version (CBIT-HK) routine tests (short line cancellation test, letter cancellation test, star cancellation test and line segment bisect), and the scores of Mini-Mental State Examination (MMSE), Fugl-Meyer Assessment (FMA) and Activities of Daily Living (ADL) were compared.Results One week after treatment, four scores of CBIT routine tests almost improved (t>2.712, P<0.05), and the score of line segment bisect was significantly better in the experiment group than in the control group (t=4.822, P<0.001). Three weeks after treatment, four scores of CBIT routine tests and the scores of MMSE, FMA and ADL improved in both groups (t>1.596, P<0.05), and the scores of short line cancellation test, letter cancellation test and line segment bisect were significantly lower in the experiment group than in the control group (t>3.577, P<0.01).Conclusion The action observation therapy could faciliate to improve the lateral neglect of patients after stroke.
