Needle electromyography in the assessment of neuromuscular state of urethral and anus sphincters in stress and urgent urinary incontinence in women
One of the possible causes of urinary incontinence (UI) may be a lesion of the pudendal nerve innervating the transverse striated muscle of the external urethral sphincter. In this case the most adequate method to assess the state of sphincters and pelvic floor muscles, to reveal the presence of denervation and degree of reinnervation in these muscles is needle electromyography (EMG), which is based on the study of motor units of muscles by analyzing their potentials recorded with concentric needle electrodes.
