About
We aimed to establish the reduction of labor pain by applying TENS at acupuncture points during the first stage of labour, to assess their efficacy, and to ascertain their acceptability.
Full description
We conducted a double-blind, placebo-controlled randomised trial involving healthy parturient at term pregnancy using TENS on 4 acupuncture points (Li 4 and Sp 6) (n=50) and the placebo group (n=50). Visual analogue scale (VAS) was used to assess the effect on pain before the application, 30 minutes and 60 minutes after TENS. The objective parameter of outcome was the score of VAS decreased in each groups. A post-partum questionnaire was given 24 hours later to evaluate the satisfaction and the use of this pain relieving method for the next delivery.
