Study 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.

Read the detailed description
  1. Subjects:

    Fifty six patients of both genders with age 40 - 60 year old suffering from suffering from constipation, physical and functional limitations will participate in this study. The participants will be 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.

    Group (B): 25 patients received anti-inflammatory diet program for 4 weeks.

  2. Equipment:

Therapeutic equipment:

  • Repetitive transcranial magnetic stimulation: a non-invasive treatment modality that operates by generating a strong magnetic field through brief, high-intensity electric currents within a coil. This magnetic field penetrates the scalp and skull without attenuation, producing localized induced electric fields in targeted brain regions.
  • Anti-inflammatory diet: Eating certain foods to increase the good bacteria and thus improve your intestinal flora as kefir, yogurt, sauerkraut, and kombucha.

Measurement equipment:

  • Health-Related Quality of Life (HRQOL): 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.
  • Constipation Severity Index (CSI): 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.
  • Interlukins inflammatory markers (IIM): particularly pro-inflammatory cytokines such as IL-6, IL-1β, and IL-17, are central to the pathogenesis of Crohn's disease, driving the transmural inflammatory response and tissue damage. Monitoring these biomarkers offers objective evidence of systemic and mucosal inflammation levels.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
