Labor pain is one of the most severe pains that women experience during their life (Lee et al., 2004). It is viewed as a complex physiological phenomenon that encompasses psychological, emotional, spiritual and physical dimensions. This approach represents a shift from the medical model (Adams, 2006). In a study by Bonica et al. (1990), 77% of primiparous reported severe or unbearable pain during labor and they also found that 35% of primiparous women had an unbearable pain, 37% sever pain and 28% had a moderate pain during their labor and delivery experience (Bonica et al., 1990).
