The objective of this systematic review was to evaluate the maternal and neo-natal results generated from the utilization of non-pharmacological methods for pain alleviation concerning the strains of delivery, classified as light-to-hard technology. Research was carried out in the following databases: CINAHL, MEDLINE, LILACS, SciELO, SCOPUS, and Isi Web of Science. This study is composed of 12 randomized eligible clinical tests published between 1980 and 2009 which evaluated immersion baths, massages, and aromatherapy. Results show that the immersion bath should be initiated after 3 cm of dilation in order not to prolong the strains of delivery and harm neo-natal results. Massage is efficient in alleviating anxiety, pain, and stress, being most effective in reducing pain when utilized in the beginning of the latent phase. Aromatherapy diminishes anxiety and fear. It is necessary to establish parameters for the application of each method in order that maternal and neonatal results are positive and contribute to the woman's satisfaction.
