Background: Pelvic floor muscle dysfunction (PFMD) is gynecologic health problem caused by  damage, weakness and degeneration of pelvic floor, it is clinically identified through testing various  parameters of the pelvic floor including pelvic floor muscle weakness, lack of muscle coordination,  excessive muscle tension, and unregulated sensory-motor processing. Consequently, pelvic floor  muscle training is considered the first treatment proposed for pelvic floor muscle dysfunction and it is  widely recommended due to its effectiveness as well as non-invasive method. Quasi- experimental 
research design was utilized in this study. The aim: this study aimed to compare the effect of electromagnetic stimulation chair with or without birth ball on pelvic floor muscle dysfunction.Settings: The study was conducted at pelvic floor rehabilitation clinic (private clinic). Subjects: A convenient sample of 40 out of 80 women was selected from the previously mentioned setting. Tools:Three tools were used for data collection. The first tool was basic data structured interview to identify women's-demographic data, reproductive history and medical &surgical history. The second tool was Pelvic Floor Interview Schedule. The third tool was Pelvic floor muscles strength test (Manometric assisted biofeedback) MBF: Results: Findings of the present study revealed that there is no any a statistically significant difference in relation to their age. On measuring the pelvic floor muscles strength in the present study, it was noticed that there is no statistically significant difference between the study group (1) and study group (2) at pre intervention (p=0.208). After six weeks and three months from intervention, it was showed a highly statistically significant difference between the two study groups where (p=0.003, p=0.001). Conclusion: The study concluded that, women who practiced active training of pelvic floor muscles by using birth ball with electromagnetic stimulation chair exhibited less signs and symptoms of pelvic floor muscle dysfunction, increased muscle strength and low recurrence rate compared to women who received passive training by using electromagnetic stimulation chair alone with a statistically significant difference over a period of six weeks and three months after the implementation of the exercise program. Recommendations: In service training program should be carried out for nurses to upgrade their knowledge regarding the importance of pelvic floor muscle training (kegel's exercise) during pregnancy, postpartum and during each  developmental phase of women's life span.
