Brief Summary:
A well-managed bowel program is an essential part of daily life for many people with a SCI. Nevertheless, constipation is frequently reported (42-95%). Constipation embraces a spectrum of harms including both physical & psychological distress. Initial exploratory studies suggest abdominal FES may be useful for decreasing overall bowel management time, decreasing colonic transit time and reducing discomfort. The current study will seek to reproduce previous findings in a 12 week study, using overall bowel managementitme as a benchmark for establishing proof of principle. The study will include 36 people with a spinal cord injury aged 18 and over with an above T12 injury, a complete or incomplete lesion in a medically stable condition, one year or more after injury. Participants will be randomised into two groups. One group will receive abdominal electrical stimulation and the other group low dose abdominal electrical stimulation. Participants will be asked to keep a bowel diary and complete questionnaires examining quality of life and bowel management.

Layout table for eligibility information
Ages Eligible for Study:   18 Years to 100 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

People with a diagnosis of SCI (age=>18) above T12 complete or incomplete lesion in a medically stable condition with a reflex bowel =>1 year post spinal injury).


Exclusion Criteria:

A history of organic bowel obstruction, frequent opioid use, intrathecal baclofen or percutaneous endoscopic gastrostomy, inflammatory bowel disease, abdominal hernia, any gastrointestinal or abdominal surgery (not necessarily excluded unless recent will require further investigation), lower motor neuron lesions, suspected strictures or fistulae along the gastrointestinal tract, physiologic gastrointestinal obstruction. Other causes of constipation such as hypothyroidism, hypercalcaemia and a prior history of constipation predominant IBS prior to diagnosis of SCI. Involvement in other research trial interventions likely to have an impact on the protocol or results of the current study.

Contra indications to electrical stimulation Poorly controlled epilepsy, cardiac pacemaker in situ or other implanted electrical devices (will require further investigation to examine whether there is an interaction between the device and FES) pregnancy or pregnancy planned, cancerous tissue in the abdominal region, any major skin disorders affecting the abdominal area) severe autonomic dysreflexia (tested at initial assessment).
