摘要：The Undergraduate Nursing Course has been using videos for the past year or so.
Videos are used for many different purposes such as during lessons, nurse refresher
courses, reinforcement, and sharing and comparison of knowledge with the
professional and scientific community. The purpose of this study was to estimate
the efficacy of the video (moving an uncooperative patient from the supine to the
lateral position) as an instrument to refresh and reinforce nursing techniques. A twoarm randomized controlled trial (RCT) design was chosen: both groups attended
lessons in the classroom as well as in the laboratory; a month later while one group
received written information as a refresher, the other group watched the video. Both
groups were evaluated in a blinded fashion. A total of 223 students agreed to take part
in the study. The difference observed between those who had seen the video and
those who had read up on the technique turned out to be an average of 6.19 points in
favour of the first (P\0.05). The results of the RCT demonstrated that students who
had seen the video were better able to apply the technique, resulting in a better performance. The video, therefore, represents an important tool to refresh and
reinforce previous learning.
