PURPOSE: This study's aim was to investigate the effects of an action observational training in subactue stroke patients with moderate impairment. METHODS: 22 participants (men = 13, women = 9) with hemiparesis were randomly assigned to action observation training group or task-oriented training group. Patients in both group underwent a patient-specific multidisciplinary rehabilitation program. Participants in the action observation group (mean age, 62.78 +/- 9.85) were asked to watch the video scene, in the knowledge that they would then attempt to perform the same movement task after watching. The control group (mean age 61.49 +/- 8.64) practiced the same tasks, without watching the video. To evaluate upper limb function, the upper extremity part of the Fugl-Meyer Assessment upper extremity and the Box and Block Test were used. The modified Barthel index was used to assess ADLs, and the modified Ashworth scale were used to assess spasticity in the upper extremity. RESULTS: The action observational training group exhibited greater changes in the Fugl-Meyer assessment upper extremity (p < 0.05; 95% CI 0.929 to 6.403), the Box and Block test (p < 0.05; 95%CI 0.086 to 5.913), and the modified Barthel index (p < 0.01; 95% CI 2.483 to 12.627) between groups. And the modified Ashworth scale (p > 0.05; 95% CI -0.402 to 0.624) did not show significantly different between groups. CONCLUSION: These findings suggest that action observational training may be more helpful to improve upper-extremity function than physical training only in subactue patients with moderate impairment after stroke.
