Sample size calculation
This study was a randomized controlled trial where in two groups were established based on the pre-experiment outcomes. The sample size for this study was calculated based on the primary outcome of visual analogue scale. According to the literatureThe allocation of participants into the test and control groups followed a 1:1 ratio. Each group initially consisted of 16 cases, and the sample size was increased by 20% to account for potential factors including loss of visits and attrition. Consequently, a minimum of 20 cases per group was required for the study subjects.
