Background: Postpartum back pain, is a major public health problem worldwide. It is associated with low quality of life, high morbidity and mortality rates, and huge socio-economic burden. Purpose of this study: was to investigate the effect of acupuncture-like TENS on back pain after delivery. Methods: Thirty postpartum women with back pain, aged 25-40 years, with BMI ranged from 25 to 30 kg/m2, were selected from Gynecology Department in Zayed Specialized Hospital Giza, Egypt. They were divided randomly into two groups equal in number. Group (A) (study group) (n=15) received acupuncture-like TENS for 20 minutes and strengthening exercises for core muscles for 60 minutes 3 times / week for 4 weeks, while group (B) (control group) (n=15) received strengthening exercises for core muscles only for 4 weeks as in group (A). Pain intensity was assessed through measuring serum cortisol level and using visual analogue scale pre and post treatment for both groups (A & B). Results: the results showed that there was a statistical significant decrease in cortisol level and pain intensity post treatment compared to pre treatment values between both groups with (p value) (0.012) and (0.001) respectively in favor to group (A). Conclusion: It could be concluded that acupuncture-like TENS was effective in management of low back pain after delivery.
