Abstract:

Objective To observe the effect of motor imagery therapy on hand function and motor imagery ability of stroke patients.
Methods From March, 2018 to March, 2020, 41 stroke patients in Beijing Bo'ai Hospital were selected and randomly divided into control group (n = 20) and observation group (n = 21). Both groups received conventional rehabilitation training, and the observation group received motor imagery therapy in addition, for four weeks. Before and after training, the scores of Fugl-Meyer Assessment-Hand (FMA-H) and Kinesthetic and Visual Imagery Questionnaire-10 (KVIQ-10), and the accuracy of mental rotation task were compared between two groups.
Results One patient in the observation group dropped down. Before training, there was no significant difference in the scores of FMA-H and KVIQ, and the accuracy of mental rotation task between two groups (P > 0.05). After training, all the indexes improved in both groups (t > 6.611, P < 0.001), and the scores of FMA-H (t = 3.742, P < 0.001) and KVIQ (t = 4.122, P < 0.001), and the accuracy of mental rotation task (t = 2.075, P < 0.05) were higher in the observation group than in the control group.
Conclusion Motor imagery therapy could facilliate the recovery of hand dysfunction and improve the motor imagery ability of stroke patients.
