The effect of an abdominopelvic exercise program alone VS in addition to postural instructions on pelvic floor muscle function in climacteric women with stress urinary incontinence. A randomized controlled trial.

INTRODUCTION

Scarce literature exists regarding the influence of posture-based interventions for the treatment of stress urinary incontinence (SUI).

OBJECTIVE

The aim of this randomized controlled trial with two parallel groups was to investigate whether the addition of postural instructions to a 12-week abdominopelvic exercise program is superior to an abdominopelvic exercise program alone, in terms of PFMs function and symptoms in climacteric women with SUI.

METHODS

Climacteric women aged between 40-75 years old who presented with SUI were included in this parallel study (NCT03727945). Two randomized groups performing one 40-minutes session per week for 12-weeks were compared: one performing an abdominopelvic exercise program (AEP) and a second one performing the same intervention with the addition of postural instructions (AEPPI). PFMs electromyographical (EMG) activity and strength (Oxford Grading Scale) were quantified during a maximal voluntary contraction. SUI symptoms were assessed using a 3-day bladder diary. These outcomes were collected at baseline, immediately after intervention, and 3-months after the intervention.

RESULTS

A total of 47 women were included in the study (AEP [n = 23], AEPPI [n = 24]). Between-group analysis showed significant differences for post-intervention EMG and strength values, showing higher values for the AEPPI compared to the AEP group. At 3-months follow-up, statistically significant differences were only obtained in strength, with higher values in the AEPPI group. No significant differences were obtained in terms of UI symptoms.

CONCLUSION

A 12-session abdominopelvic exercise program supplemented with postural instructions is superior to an abdominopelvic exercise program alone in terms of PFMs function in women with SUI.
