      <study_design>Randomization: Randomized, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Participants were randomly assigned to the three groups of 40 recipients of TENS  and Entonox gas and other group without any intervention using the Select (randbetween (1; 2)) command, in the Excel computer program.</study_design>

      <hc_freetext>The comparison of TENS and Entonox on delivery pain.</hc_freetext>
      <i_freetext>Intervention 1: Intervention group 1: the effect of TENS on labor pain. In the TENS group, first place the electrodes at the appropriate place behind the patient. The electrodes are parallel to the spine. The first pair of electrodes is placed between the tenth thoracic and the first lumbar vertebra. The second pair of electrodes is placed between the second to fourth sacral vertebrae. Then,  mother  can change the frequency of the device from low (at least pain relief) to high (maximum pain relief). Intervention 2: Intervention group 2: the effect of Entonox gas on delivery pain. In the Entonox group, we first teach to the patient how to use Enonox gas. Gas usage should begin at the beginning of uterine contraction. The capsule should be shaken before use. Gas inhalation will be continued with a deep inhalation, a pause at the end and a rest phase. By the of uterine contraction, the gas inhalation will be stopped and the patient will use the room air. We will stopp using Entonox when the patient won't cooperate or the level of the patient's consciousness will be decreased. Intervention 3: Control group: without any intervention.</i_freetext>
