This study aims to determine the effect of adding interferential current to pelvic floor muscle training on vaginismus.

Vaginismus is a common sexual problem with a prevalence of 20% in Egyptian women, that has a significant impact on a person's life, affecting their physical, emotional, and psychological well-being, as well as their relationships and overall quality of life.

There were previous studies that studied the effect of pelvic floor rehabilitation on vaginismus and found that there was a highly significant decrease in pain and pelvic floor muscle spasms, as well as a highly significant increase in sexual function. Also, only one previous protocol explored the effect of interferential current on treating vaginismus. But, till now, there is no prior study that investigated the impact of adding interferential current to pelvic floor muscle training on treating vaginismus. this trial has two groups; one will receive interferential current, and the other group will receive interferential current + pelvic floor muscle training
