During pregnancy, there are notable alterations in biomechanics, hormones, and vascular functioning, which frequently result in a range of musculoskeletal ailments, including back pain, leg cramps, and pelvic girdle discomfort. The significance of pregnancy-related musculoskeletal problems on women's daily functioning and general well-being is highlighted by their widespread occurrence worldwide, necessitating heightened focus and implementation of effective therapeutic approaches. The main aims of this study were to assess the effectiveness of prenatal exercises in musculoskeletal discomfort and investigate the association between post-intervention levels of discomfort and certain demographic factors. A quantitative technique was used in this study, utilizing a pre-experimental design conducted for three months. A total of 60 primigravida mothers were selected as participants through purposive sampling. The study was conducted in a Maternity Tertiary Care Center located in Tamil Nadu. The intervention encompassed the provision of antenatal exercises, specifically focusing on abdominal tightness, pelvic tilting, and foot and ankle movements. The researcher demonstrated the exercises for 20 minutes, and afterward, mothers were asked to perform the activities themselves. The process was monitored and observed for two weeks. The findings were statistically significant, suggesting a noteworthy decrease in musculoskeletal disorders following the implementation of the intervention. The statistical analysis revealed a significant degree of significance (P = 0.001), confirming the efficacy of the exercises. Before the implementation of the intervention, a significant proportion of mothers, namely, 45 (75%) reported experiencing moderate back pain. However, following the intervention, this percentage notably fell to 33.34% (20). The incidence of moderate pelvic pain decreased from 80% (48) to 30% (18), and a comparable pattern was observed in the reduction of leg cramps. Additionally, the research identified significant associations between the improvements and a range of demographic and obstetricfactors, including the level of education, occupation, family structure, age at marriage, and weight of the mother. The results highlight the significance of incorporating antenatal exercises as a regular component of prenatal care to minimize musculoskeletal discomfort, hence promoting the overall health and well-being of expectant mothers.
