NCT07531342

Brief Summary

Fifty six patients with Crohn's disease of both genders with age 40 - 60 year old suffering from constipation, physical and functional limitations participated in this study. The participants were selected from Outpatient clinic of Faculty of Physical Therapy, Suez Canal University, Egypt and randomly distributed into two groups equal in number. Group (A): 25 patients who received rTMS 5 times per week in addition to anti-inflammatory diet for 4 weeks. While, Group (B): 25 patients received anti-inflammatory diet program for 4 weeks. Primary outcome measures were Quality of life questionnaire and Constipation severity index while Interlukins inflammatory markers was the secondary outcome measure.

Outcome Measures

Primary Outcomes (2)

  • Health-Related Quality of Life (HRQOL)

    HRQOL is serving as a primary indicator of therapeutic success. In patients with CD, HRQOL is often compromised by both physical symptoms and psychological distress. Utilizing specialized instruments such as the Inflammatory Bowel Disease Questionnaire (IBDQ) or the Short Form-36 (SF-36) allows researchers to quantify the holistic benefits of multimodal interventions, including neuromodulation via rTMS and dietary modifications, which aim to alleviate the psychosocial burden and functional limitations associated with chronic intestinal inflammation.

    4 weeks

  • Constipation Severity Index (CSI)

    CSI is evaluating the intensity of these symptoms across sub-domains including obstructive defecation and colonic inertia. In the context of rTMS and anti-inflammatory diets, the CSI provides a sensitive measure to track how brain-gut axis modulation influences bowel frequency and ease of evacuation, offering a standardized numerical value to assess the reduction in clinical symptom severity over the course of the intervention.

    4 weeks

Secondary Outcomes (1)

  • Interlukins inflammatory markers (IIM)

    4 weeks

Study Arms (2)

Repetitive transcranial magnetic stimulation combined with anti-inflammatory diet

EXPERIMENTAL

25 patients received 1 Hz rTMS, the right dorsolateral prefrontal cortex (DLPFC) was selected as the stimulation site plus anti-inflammatory diet (unprocessed, anti-inflammatory foods, rich in microbiota-accessible carbohydrates, lean protein, and omega-3 fatty acids) for a period of 4 weeks.

Device: Repetitive transcranial magnetic stimulationDietary Supplement: Anti-inflammatory diet

Anti-inflammatory diet

EXPERIMENTAL

25 patients received anti-inflammatory diet (unprocessed, anti-inflammatory foods, rich in microbiota-accessible carbohydrates, lean protein, and omega-3 fatty acids) for a period of 4 weeks.

Dietary Supplement: Anti-inflammatory diet

Anti-inflammatory dietRepetitive transcranial magnetic stimulation combined with anti-inflammatory diet

Patients received 1 Hz rTMS, the right dorsolateral prefrontal cortex (DLPFC) was selected as the stimulation site. The stimulation frequency was set to 1 Hz for a period of 4 weeks.
