Effect of Dynamic or Static Hand Action Observation on Chronic Non-fluent Aphasia after Stroke / 中国康复理论与实践

ABSTRACT

Objective:To compare the effects of observation to non-goal-oriented hand actions with video or pictures on speech recovery in stroke patients with chronic non-fluent aphasia. Methods:From January, 2016 to December, 2018, 30 patients with non-fluent aphasia after stroke were randomly divided into two groups. The control group (n = 15) repeated the verbs after watching picture, and the experimental group (n = 15) repeated the verbs after watching videos, for four weeks. They were assessed with Western Aphasia Battery (WAB) before treatment and every week after treatment. Results:Aphasia quotient (AQ) increased with time (F > 32.922, P < 0.001), but no significant difference was found between two groups at any time points (t < 0.699, P > 0.05). The interactive effect between time and group was significant (F = 6.398, P < 0.001), which suggested that AQ increased more in the experimental group than in the control group. Conclusion:For non-goal-oriented hand action observation, video observation maybe promote speech recovery in stroke patients with chronic non-fluent aphasia.
