Effect of purposeful action observation on upper extremity function in stroke patients.
[Purpose] The purpose of this study was to identify the effect of purposeful action observation on upper extremity function in patients with stroke. [Subjects and Methods] Twelve subjects were randomly to either the experimental group or control group. The experimental group underwent occupational therapy and a purposeful action observation program. The control group underwent occupational therapy and placebo treatment in which the subjects performed a purposeful action observation program without actually observing the purposeful actions. The Wolf Motor Function Test was used to measure upper extremity function before and after the intervention in both groups. [Results] Both the experimental and control groups demonstrated improved upper extremity function after the intervention, but there was no significant difference between groups. Compared with before the intervention, the experimental group showed significantly improved upper extremity function after the intervention. [Conclusion] Based on these results, a purposeful action observation program can improve upper extremity function in patients with stroke. In future research, more subjects should be included for evaluation of different treatments.
