Arm | Intervention/treatment |
---|---|
Experimental: Epidural stimulation for blood pressure without stand
To assess whether epidural stimulation, used for regulating blood pressure without standing, is neuromodulatory for bowel motility after motor complete SCI
|
Device: Stimulation for blood pressure without stand
Consists of 80 daily training sessions using epidural stimulation optimized for blood pressure for up to 6 hours of stimulation a day. |
Experimental: Epidural stimulation for blood pressure with stand
To assess whether epidural stimulation, used for regulating blood pressure with standing, is neuromodulatory for bowel motility after motor complete SCI
|
Device: Stimulation for blood pressure with stand
Consists of 80 daily sessions similar to the 1st intervention (without stand) plus 2 hours of epidural stimulation optimized for stand training. |
Experimental: Epidural stimulation for trunk and core without stand
To assess whether epidural stimulation, used for activating the trunk and core musculature without standing, is neuromodulatory for bowel evacuation after motor complete SCI
|
Device: Stimulation for trunk and core without stand
Consists of 80 daily training sessions using epidural stimulation optimized for trunk/core/voluntary function for up to 6 hours of stimulation a day. |

- Wireless Motility Capsule [ Time Frame: Change from Baseline after 4 months, 8 months, 14 months, 20 months. ]Use of the FDA approved SmartPill and device to record information about motility.
- Ambulatory blood pressure and heart rate monitoring [ Time Frame: Change from Baseline after 4 months, 8 months, 14 months, 20 months. ]Blood pressure will be recorded over a 24-hour period of time outside the lab using a flexible finger cuff on your non-dominant hand.
- Anorectal Manometry (ARM) [ Time Frame: Change from Baseline after 4 months, 8 months, 14 months, 20 months. ]
While lying on your side, while a small, flexible tube, about the size of a thermometer, with a balloon at the end will be inserted into the rectum.
The catheter is connected to equipment that measures pressure. A small balloon attached to the catheter may be inflated in the rectum to assess muscle responses.
You will be asked to relax, squeeze, and push at various times. The anal sphincter muscle pressures are measured during each of these muscle contraction/relaxation actions.
Surface patch EMG electrodes will be placed near the buttocks to evaluate muscle activity of the anal sphincter.
- Bowel Diary [ Time Frame: Change from Baseline after 4 months, 8 months, 14 months, 20 months. ]Keep a log of various aspects of your bowel program, including how often and how long it takes you to complete your program.
- International spinal cord injury bowel function basic data set (Version 2.0) [ Time Frame: Change from Baseline after 4 months, 8 months, 14 months, 20 months. ]Complete a short questionnaire about your bowel management. 16 items: date of data collection, gastrointestinal and anal sphincter dysfunction unrelated to SCI, surgical procedures on the gastrointestinal tract, defecation method and bowel-care procedures, average time required for defecation, frequency of defecation, uneasiness, headache or perspiration during defecation, digital stimulation or evacuation of the anorectum, frequency of fecal incontinence, flatus incontinence, need to wear pad or plug, oral laxatives and prokinetics, anti-diarrheal agents, perianal problems, abdominal pain and discomfort and the neurogenic bowel dysfunction score are computed by adding the points given in parenthesis after each relevant variable in the data-set. Total score range is from (0-45). Total neurogenic bowel score (optional): 0-6 Very minor, 7-9 Minor, 10-13 Moderate, 14 or more, Severe neurogenic bowel dysfunction.
- Quality of Life Questionnaire measured with the Spinal Cord Injury - Quality of Life (SCI-QOL) items relevant to bowel management. [ Time Frame: Change from Baseline after 4 months, 8 months, 14 months, 20 months. ]Complete a series of short questionnaires about your quality of life. SCI-QOL measurements scores range from (0-100). It includes 19 calibrated items banks and 3 fixed length scales spanning the broad domains of physical-medical health, emotional health, social participation and physical functioning.
- Interviews [ Time Frame: Change from Baseline after 4 months, 8 months, 14 months, 20 months. ]Interviews about your perspective on changes in bowel management and recovery throughout the study, conducted by a qualitative researcher.
