Following spinal cord injury signals between the brain and the bladder are disrupted. As a result the bladder often becomes overactive which can lead to the need for frequent trips to the toilet, regular incontinence episodes and a decreased quality-of-life. Neuromodulation is a therapy that aims to target the nerves that become overactive controlling the bladder, stopping the bladder overactivity on demand using an external (non-invasive) nerve stimulation box and sticker electrodes placed on the penis or clitoris.
This study is a pilot study that aims to investigate neuromodulation for improving symptoms of bladder overactivity when used by 10 people over eight weeks at home. We will assess whether using the device improves bladder capacity, incontinence, frequency of needing the toilet and whether there are any longer lasting changes after 8 weeks. Finally, the study will aim to find out the acceptability of using this type of therapy for participants and the acceptability of the device we are using.
Participants in this trial will participate over 13 weeks and need to visit our centre in Stanmore to have urodynamics tests in the 1st, 9th and 13th week. At home they will use a small stimulation device on a daily basis for 8 weeks to control overactivity in the bladder. Whilst at home they will record relevant outcomes in several three-day diaries and questionnaires. They will record baseline data before starting stimulation and for 4 weeks after.

| Neuromodulation | Device | Transcutaneous stimulation of the dorsal genital nerve using the Innocon Medical UCon device to provide on demand relief of bladder spasms |

| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline (week 1) in Maximum Cystometric capacity at post intervention (week 9) and follow up (week 13). | During standard cystometry (retrograde filling of the bladder), maximum cystometric capacity will be defined as the volume emptied from the bladder after each fill. | Week 1, 9 and 13 |
| Measure | Description | Time Frame |
|---|---|---|
| Maximum detrusor pressure | Maximum recorded detrusor pressure during standard cystometry (retrograde filling of the bladder). | Week 1, 9 and 13 |
| 3 day bladder diary (3DBD) | 3DBDs will be completed on clinically used bladder diaries. Participants will record voided volumes, urinary and faecal incontinence episodes and daily spasticity for 3 days. This will involve measuring the volume voided each time they urinate over the three days, using provided measuring equipment. |
