Electromyographic Evaluation of the Pelvic Muscles Activity After High-Intensity Focused Electromagnetic Procedure and Electrical Stimulation in Women with Pelvic Floor Dysfunction

Abstract

Electromyography (EMG) effectively measures pelvic floor muscle (PFM) activity, revealing differences in muscle function in women with pelvic floor dysfunction (PFD). This study compares the efficacy of high-intensity focused electromagnetic (HIFEM) therapy and traditional electrical stimulation in treating PFD. Surface EMG and subjective assessments (Pelvic Floor Impact Questionnaire, PFIQ) were used to evaluate PFM strength, endurance, and relaxation changes. Results showed that HIFEM significantly improved muscle activation, relaxation, and endurance compared to electrical stimulation. The PFIQ scores also indicated a more significant improvement with HIFEM, suggesting it is more effective than electrical stimulation for restoring PFM strength and alleviating PFD symptoms. These findings highlight HIFEM’s superior efficacy in PFM rehabilitation, offering a promising alternative for postpartum women and those with urinary incontinence or sexual dysfunction.
