The aim of this study is to develop improved methods of restoring function to the neurogenic bladder, using electrical stimulation without cutting nerves in patients with spinal cord injury. The investigators will test 5-10 subjects with existing sacral anterior root stimulation (SARS) devices and look at the effects of high frequency (up to 600Hz) compared to the usual low frequency stimulation on bladder function. The investigators are particularly interested in whether it is possible to reproduce a 'functional' dorzal rhizotomy using high frequency stimulation of the S2 efferent nerves
