SCI: Fiber and Neurogenic Bowel (2007)
- To assess if a therapeutic protocol, which combines the means to accelerate large bowel transit and to trigger the defaecatory act, can increase the frequency and optimize the timing of bowel movement, and thus decrease the necessity for the use of oral laxatives and/or enemas in SCI patients.
- SCI patients who had chronic constipation and required use of different stimuli for bowel evacuation.
None specifically mentioned.
Recruitment: methods not described
Design: Nonrandomized Clinical Trial
Blinding Used (if applicable): not applicable
Intervention (if applicable)
4 weeks of treatment:
- Interrupt enemas and/or laxatives.
- Mediterranean diet: 15g of fibers and 1500 ml/24h water, enriched with vegetables and fruit.
- Gradual and sequential stimuli.
- Score 1: Abdominal massage
- Score 2: Perianal digitations
- Score 3: Ano-rectal digitations
- Score 4: Glycerin suppository
- Score 5: Rectal laxatives
- Score 6: Oral laxatives.
Progress to the successive stimulus only if the preceding one is unsuccessful.
Statistical Analysis: Statistical analysis carried out by means of Wilcoxon's test.
Timing of Measurements
- Variables were assessed in basal condition and after 4 weeks of treatment.
- Bowel movement frequency; bowel habit; total and segmental
- Therapeutic protocol based on high residue diet, standardized water intake, and use of sequential schedule of evacuating stimuli
Initial N: 10 SCI patients, 5 male, 5 female
Attrition (final N): 10
Age: mean age 33 years, range 20 - 60 years
Ethnicity: not mentioned
Other relevant demographics: SCI level ranged from C3 to L4
- In the basal period, four and two patients used oral and rectal contact laxatives, respectively. At the end of the training period no patient took contact laxatives orally, and two used laxative suppositories. The score which expressed the degree of altered evacuation in accordance with the sequential schedule was 4.5±1.9 in the basal period, and 3.1±2.7 during the training period (P<0.05)
- Reported bowel frequency was 2.9±2 events per week in the basal period, and 4.1±3 events per week at the end of the training period.
- The total GI transit time (TGITT) was significantly reduced at the end of the study (146±15 vs. 86±17; P<0.01).

- Protocol was clearly explained; intervention was conducted with high compliance rate (100%).
- High compliance rate (100%).
- Small sample size; however, clinical significance of the effectiveness of the treatment were evident.
- Inclusion/exclusion criteria and recruitment methods not well described.
