Aim This study aims to determine the effectiveness of home‐based pelvic floor muscle training (PFMT) on decreasing the severity of symptoms and improving the quality of life (QOL) among Omani women with stress urinary incontinence (SUI). Methods A randomized controlled single‐blind trial was conducted in three primary health care centers in Muscat. Eligible women who were diagnosed with SUI (from a concurrent phase‐I study which was a cross‐sectional study to determine the prevalence of urinary incontinence in Oman) were invited to take part. The consenting subjects were randomly allocated to either an intervention group (unsupervised PFMT) or a control group (lecture with no PFMT). Baseline and 12‐week assessment of both groups was carried out for the primary outcome using the validated Arabic version of the International Consultation on Incontinence Questionnaire (ICIQ)‐short form and the secondary outcome by blinded measures of pelvic floor muscle (PFM) strength using the modified Oxford grading system (MOGS), endurance, and perineometer. Results A total of 73 subjects were included in the study. They were randomly divided into two groups. Both groups were similar at the baseline in terms of sociodemographic characteristics, ICIQ score, and PFM strength. At the 12‐weeks assessment, there was a significant difference in the ICIQ score (P < .001) between the intervention group and the control one. There was no statistical difference between the two groups in MOGS, endurance, or perineometer values. Conclusions The home‐based PFMT is an effective treatment in reducing the severity of symptoms and improving the QOL in women with SUI.
