Electrical Stimulation for Continence After Spinal Cord Injury

Inclusion Criteria: Subjects will be included if they meet all of the following criteria: * Complete spinal cord injury (AIS grade A) of at least 2 years duration with neurological level (ISNCSCI level) below C4 * Impaired bladder emptying due to Detrusor External Sphincter Dyssynergia-DESD (unco-ordinated contraction of bladder and external urethral sphincter) as shown on video-urodynamic testing. * Impaired continence due to detrusor hyper-reflexia Exclusion Criteria: Subjects will be excluded if they meet any of the following criteria: * Absence of reflex contractions of the bladder as shown on urodynamic testing * Absence of reflex contractions of the external urethral sphincter as shown on urodynamic testing with EMG * External sphincterotomy, urethral stricture or previous urethral or sphincter or bladder or prostate surgery * History of pelvic fracture * Subjects on anticoagulants or with coagulation disorders * Immunosuppressed subjects * Active or recurrent pressure ulcers, particularly in sacral, ischial or trochanteric areas * Active untreated infection * Active implanted medical device such as cardiac pacemaker or defibrillator * Progressive spinal cord injury * Pregnancy * Mechanical ventilator dependency * Any other significant co-morbidity or illness that would preclude their participation or increase the risk to them of participating in the study * Inability or unwillingness to follow study protocol or give informed consent
