Transcutaneous Tibial Neuro-stimulation to Improve Voiding Dysfunction in Multiple Sclerosis.

This study tests whether a non-invasive nerve stimulation technique — applying mild electrical pulses to the ankle area (transcutaneous tibial nerve stimulation) — can help people with multiple sclerosis (MS) who have trouble emptying their bladder and rely on self-catheterization. **You may be eligible if...** - You have a confirmed diagnosis of multiple sclerosis - You have a bladder condition called bladder-sphincter dyssynergia (where the bladder and sphincter don't coordinate properly) - You rely on clean intermittent self-catheterization to manage your bladder - You have social insurance coverage **You may NOT be eligible if...** - You have another neurological condition in addition to MS - Your MS disability score is 6 or higher (meaning you need significant assistance to walk) - You have frequent urinary tract infections (more than 3 per year) - You have had tibial nerve stimulation in the last 3 months - You have a pacemaker, metal leg prosthesis, or are pregnant - You have had botulinum toxin injections to the bladder in the last 9 months Talk to your doctor to see if this trial is right for you.
