The working postures of the students were video-recorded as they worked in a self-position and guided position, and the working postures were assessed using RULA, REBA and M-DOPAI. After excluding three participants who withdrew from the study, 28 were included in the final analysis. The data were analysed using the Wilcoxon signed-rank test and Kruskal–Wallis test with statistical significance set at 0.05.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>The total RULA, REBA and M-DOAPI scores improved for all clock positions (<i>p</i> &lt; 0.05).

The M-DOPAI score showed positive work position changes in all body parts in all clock positions except the hips in the 10–11 o'clock position, and there was a significant difference in the head and neck and wrists (<i>p</i> &lt; 0.05).

Due to the scarcity of studies on involuntary oral care provision, the strategy to reach the aim was to identify barriers and facilitators for providing involuntary care in general, and to infer from these barriers and facilitators for providing involuntary oral care. The online databases PubMed, CINAHL, EMBASE, and PhilPapers were searched for papers on involuntary care. In addition, three key journals and the reference lists of the included studies were hand searched for additional studies.
