In the discussion section of the research article, the authors stated that sedative music had a large effect size when compared to both usual chair rest (>1.0) and scheduled chair rest (>0.9). Furthermore, scheduled chair rest when compared with usual chair rest did not result in significantly less anxiety, pain sensation, or pain distress, but the differences were in the expected direction with small to medium effects (0.20 to 0.45). Why is this information important for future research?
