To investigate the contribution of needle electrode electromyography (EMG) in the diagnosis of vaginismus.


The electromyograhic activity of ischio-cavernosus and bulbo-cavernosus muscles was recorded by using a concentric needle EMG on 9 women with vaginismus, then compared to the EMG activity of no vaginismus women. The agreement between the needle electrode EMG and clinical exam was assessed by measuring the Cohen Kappa coefficient.


The EMG was abnormal in 7 women presenting vaginismus by showing a significant reactivity after stimulating the vaginal introitus. A hyperexcitability was found in 4 cases. The EMG and clinical findings presented a high level of agreement.


The pelvic floor muscles in vaginismus patients showed an increased EMG activity at rest and on induction of vaginismus. The needle electrode EMG can be useful for the diagnosis of vaginismus.
