The scientific work is focused on developing electrical stimulation methods to treat both bladder and bowel dysfunction. We are addressing incontinence (urinary and faecal) as methods to allow bladder and bowel emptying.
The laboratory has developed a novel closed loop method to treat neurogenic detrusor overactivity using a sensor to detect the onset of a bladder contraction and a stimulator to suppress bladder contraction.

Main Research Areas

  1. Electrodefecation
    The rectum can be activated by electrical stimulation of the sacral nerve roots. The aim is to study stimulation driven defecation using an implantable system in an animal model.
  2. Bladder sensor
    The aim is to develop an sensor that is able to detect the onset of a bladder contraction.
  3. Wireless EMG electrodes
    The aim is to develop and test 'smart' wireless EMG electrodes.
  4. Faecal incontinence
    The aim is to develop a treatment for faecal incontinence using electrical stimulation.
  5. Selective recording
    The aim is study nerve diameter selective recording using a multi-contact cuff electrode.
  6. Treatment of neurogenic detrusor activity
    The goal is to develop a closed loop electrical stimulation system that suppresses bladder activity. This system should treat the incontinence and allow for a larger bladder capacity.
  7. Stress incontinence
    The goal is to develop and test a new method to treat stress incontinence
