“…All existing studies (Tussey, et al, 2015;Roth, et al, 2016;Kwan & Mercier, 2018;Hickey & Savage, 2019)., the systematic review (Grenvik, et al, 2019) and a protocol (Stulz, et al, 2018) published with the use of PB, only use this resource after pharmacological analgesia. Therefore, our study is innovative, interesting and feasible, since, we will evaluate the effectiveness of PB in maternal fatigue in women without the use of pharmacological analgesia, which makes perfect sense, because if we obtain good results, we can implement another method not pharmacological effects during labor, positively impacting public health.…”
