We present a study on the clinical assessment of pelvic floor dysfunction in 30 female patients with proven multiple sclerosis (MS). A scoring system for pelvic floor muscle testing by digital vaginal palpation is proposed. The concept of pelvic floor spasticity in MS is introduced. The relationship of our findings with the neurological findings and urodynamic data is presented. Pelvic floor spasticity correlates well with the presence of detrusorexternal sphincter dyssynergia and with more severe spinal cord disease. Neurourol.
