Background: Primary dysmenorrhea is health related problem with high prevalence causing effects on different aspects of life affecting different activities and in turn work productivity.
Aim: To compare the effectiveness of tens vs. stretching exercises on primary dysmenorrhea.
Design: Randomized controlled trial (RCT) (double blinded).
Setting: Royal group of colleges Gujranwala, Pakistan.
Population: sixty six female students with confirmed diagnosis of primary dysmenorrhea were included. The ages of them were 16-25 year.
Methods: sixty six females were divided into two groups. The group A was treated with TENS while group B was treated with stretching exercises. The data was collected from the subjects through structured questionnaire, VAS scale and SF-36. The demographic data was presented in the form of tables. Intervention-induced changes within the groups were investigated using paired sample t-test while independent sample t-test was used to compare the two groups. Correlation was used to observe relationship of pain and different domains of quality of life.
Results: Significant changes within tens group (p ≤ 0.05) was observed for pain. Additionally, significant differences in some domains of quality of life were found between both groups. However, some domains did not demonstrate significant changes in both groups likely because duration of intervention was less.
Conclusion: It is concluded from the results that TENS is more effective for pain improvement but to improve quality of life stretching exercises are more effective.
