PEMF vs Laser for Stress Urinary Incontinence

Participants in this arm will receive pulsed electromagnetic field (PEMF) therapy to the pelvic floor area along with pelvic floor muscle training. The PEMF device generates a pulsed magnetic field with the following parameters: frequency 10 Hz, intensity 200 μT, pulse duration 250 μs. It will be applied over the pelvic floor for 20 minutes per session, 5 days per week for 8 weeks.

Participants in this arm will receive low-level laser acupuncture to pelvic floor trigger points along with pelvic floor muscle training. A continuous wave 810 nm diode laser will be used at 100 mW power and 0.5 J/point, delivered to 6 pelvic floor acupoints bilaterally (12 points total) for 15 seconds per point. Acupuncture will be performed 3 days per week for 8 weeks.
