Abstract
AIM OF THE STUDY: To investigate a more available model for the early phase of motor learning after action observation combined with motor imagery training in elderly people. To address the purpose, we focused on a slow, unskilled model demonstrating an occasional error. MATERIALS AND METHODS: A total of 36 elderly people participated in the current study and were assigned to either the unskilled or skilled model observation groups (n = 12, respectively), or the control group (n = 12). The participants in the observation groups observed the assigned a video clip of an unskilled or skilled model demonstrating a ball rotation task. During the observation, the participants were instructed to imagine themselves as the person in the video clip. The participants in the control group read a scientific paper during the equivalent period of action observation and motor imagery. We measured ball rotation performance (the time required for five rotations, the number of ball drops) in pre- and post-intervention (observation combined with motor imagery training for intervention groups or reading for control group). RESULTS:Ball rotation performance (ball rotation speed) significantly improved in the unskilled model observation group compared to the other two groups. CONCLUSIONS: Intervention for action observation using unskilled model combined with motor imagery was effective for improving motor performance during the early phase of motor learning.
