Table 1 Standardization of training and protocols
Group | Standardized training program | Detailed dosage | Time in total |
|---|---|---|---|
Active control group | Sustained contractions | Patients complete PFMT by themselves, 6–10 s for each contraction, and every two contractions are separated by a period of 10-s rest; 8–10 reps per set for 1–2 sets | 50 min |
Phasic contractions | The patient completes pelvic floor muscle contractions of 2–5 s each, followed by rest intervals of 4–10 s. Each set contains 10 contractions, 1–3 sets each | ||
Training guidance | Under the guidance of the instructor, patients perform PFMT, combined with breathing and relaxation training | ||
Group 1 | PFMT + + electromagnetic stimulation | PFMT is the same as the active control group Electrical stimulation: 20–60 Hz, the pulse width of 200–600 μs, 10 min of stimulation Magnetic stimulation: 15 Hz for 2 s and 30 Hz for 3s, with a rest interval of 5 s, 20 min of intervention Twice per week for 5 weeks |  |
Group 2 | PFMT + + electromagnetic stimulation | PFMT is the same as the active control group Electrical stimulation: 20–60 Hz, the pulse width of 200–600 μs, 10 min of stimulation Magnetic stimulation: 15 Hz for 2 s and 30 Hz for 3 s, with a rest interval of 5 s, 20 min of intervention 10 consecutive days | 50min |
