| Objective: To explore the effects of Alpha music on the power of alpha wave and cognition in patients with cognitive deficit following stroke in order to predict the existence of cognitive impairment in patients with stroke and help for future rehabilitation intervention. Method: Sixty patients with cognitive impairment following stroke were divided into experimental group (n=40) and control group (n=20). The experiment group was further sub-divided into sensitive (n=22) and non-sensitive (n=18) subgroups according to their responses to Alpha wave. All patients received routine rehabilitation therapy and nootropic drugs. The patients in experimental group received alpha music treatment additionally. The data of alpha wave 2 min before and 2 min after the play were collected in all patients. Results: (1) In the sensitive subgroup, the values of alpha wave 2 min before and 2 min after play were increased remarkably corresponding to two periods before intervention after 4-week treatment (P<0.01). After 4-week intervention, the values of alpha wave increased statistically 2 min after play in non-sensitive subgroup and control group (P<0.01 and 0.05). The values of alpha wave before and 2 min after play in sensitive group were higher than in non-sensitive group and control group (P<0.05). (2) In sensitive group, the MoCA total score, memory, visuospatial ability, attention and calculation ability score were higher than those before the intervention, as well as non-sensitive group and control group after the intervention (P<0.05 or 0.01). In non-sensitive group, the attention and calculation ability score increased sharply as compared with control group after 4-week treatment (P<0.05). In non-sensitive group, attention score increased significantly after 4-week intervention (P<0.01). Conclusion: Alpha music is an effective treatment for patients with cognitive deficit after stroke. It can improve patients' value of alpha and cognition, especially the memory, attention, calculation as well as visuospatial ability. |
