By contrast, the control group didn’t have significant higher mean score of knowledge from the pre-test to follow-up assessments.<br> <strong>Conclusion: </strong>The effectiveness of intervention on back care related knowledge was demonstrated in this study. Further evaluation is required to examine other determinants of promoting back-related behavior. https://ijmpp.modares.ac.ir/article_20168_9128f1bd1903249f745a20da0215e889.pdf
