Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is to switch off the neuromodulation device which is the implanted pulse generator that stimulates the sacral nerve. The device is switched off for 6 weeks by a nurse. To monitor adherence to the intervention the remote control which the patient usually uses to turn their device off or on is placed in a security sealed envelope. Each cycle includes 2 weeks of washout period.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All patients implanted with a permanent sacral nerve stimulator at Concord Hospital will be assessed for eligibility.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A specialist nurse, who is otherwise not involved with data collection and analysis will undertake all randomisation. Both the investigators and the patients are blinded to randomisation arm assigned. A computer generated block randomisation will be performed and sealed in an opaque envelope. The envelopes are numbered and drawn sequentially at the point of randomisation.
Masking / blinding
