Bowel Dysfunction (NBD) affects up to 80 % of the spinal cord injury (SCI) population. The validated NBD Score allows assessment of the severity of bowel symptoms and correlates with impaired quality of life but does not address clinical decision making in individual patients presenting with an ineffective bowel regimen. Therefore, Monitoring Efficacy of NBD Treatment On Response (MENTOR) was developed by a group of international experts in the field of NBD as a standardised way to quickly and accurately assess the effectiveness of NBD treatment regimen in SCI patients.
