Statistical analysis used:Data analysis was carried out using independent t-test,paired t-test and One-way ANOVA. Results:Data analysis of modified CFS showed statistically significant results for all groups between before and after treat- ment.Within CFS,results of physical and psychological analysis showed significant results for all groups except before and after no treatment and secondary treatment.In the analysis of VAS,the experimental group showed a greater decrease in score compared to that of the control group and the average difference was statistically significant(P<0.05).Although the results were not statistically significant(P>0.05),active oxygen levels for the control group showed little difference before and after no treatment(331.11 and 330.78,respectively)while the experimental group observed a decrease in active oxygen level before and after treatment(327.28 and 314.11,respectively).Conclusion:In conclusion,patients who received meridian massage showed decreased cancer related fatigue scores compared to the control.These results suggest that meridian massage may alleviate cancer-related fatigue and contribute to the improvement in quality of life among cancer patients.展开更多
