AbstractThe objectives of the study are: 1. To assess the effectiveness of birthing ball exercise on experimental and control group in labour pain in 1st stage among primigravida mothers. 2. To compare the effectiveness of birthing ball exercise in experimental group and control group in 1st stage of labour pain among primigravida mothers. Quantitative approach was used with quasi experimental research design. The researcher assessed the pain level with pain intensity scale before intervention for both the control and experimental group of primigravida mothers. The study was conducted at love N care hospital Surat. The samples of 60 primigravida mothers were selected through randomized sampling technique. Pain intensity scale was used to assess the level of labour pain during the 1st stage of labour among the primigravida mothers before and after use of birthing ball which was collected by the researcher through interview. Reliability of the tool was ascertained by Karl Pearson's coefficient correlation (r) Method. The mean pain level in the control group was after therapy (M-7.53. SD=0.90) compared to before therapy (M=7.80. SD=0.81) whereas the mean pain level was low (M=6.33, SD=0.92) after therapy in the experimental group when compared with before therapy (M=7.40, SD=0.50. It showed the effectiveness of birthing ball upon labour pain.
