Effect of Adding Interferential Current to Pelvic Floor Muscle Training on Vaginismus

It will be in the form of pelvic floor relaxation with biofeedback, as well as stretching exercises for the pelvic floor and the adjacent muscles. The patient will be asked to lie in a comfortable crock lying position. She will be instructed to do diaphragmatic breathing exercises. The vaginal electrode of the biofeedback will be gently introduced into the vagina to start pelvic floor relaxation training. Then, the patient will be asked to perform pelvic floor relaxation by slightly contracting the pubococcygeus muscle. After 10 minutes of pelvic floor relaxation training, the patient will then be instructed to return to the active state gradually, the treatment procedure will be performed 3 times/ week for 8 weeks. Stretching exercises for the pelvic floor and the adjacent muscles: Levator ani \& perineal muscles stretch, hip adductor muscles stretch, piriform muscle stretch, hip flexor muscles stretch, and obturator internus muscle stretch.

Each female in the experimental group will receive interferential current, 3o minutes per session, 2 sessions per week, for 8 weeks. The applied parameters will be a frequency of 2000Hz, a modulated amplitude of frequency of 80Hz, pulse width of 200μs, and the intensity is modulated according to the sensory level of each participant. While the participant is in a comfortable crock lying position with abducted hips, the position of the electrodes will be maintained in all sessions
