Brief Summary

Constipation consists of bowel symptoms characterized by difficulty or infrequency passage of stool, stiff stool, or a feeling of incomplete evacuation. However, its impact goes far beyond this definition. Constipation negatively impacts the quality of life (QoL) of children and adults suffering from this condition, affecting mental and physical-related QoL. Additionally, a negative impact of constipation on QoL was found in parents carrying children with constipation, affecting family functioning. People with an intellectual disability present a constipation rate of over 33%. Rett syndrome (RTT) is a complex neurodevelopmental disorder affecting about 1/10,000 females and a few males worldwide. Chronic constipation is persistent in people with RTT, with a reported prevalence higher than 74%. Specific recommendations for constipation management in RTT were developed, including behavioral, pharmacological, and surgical considerations. Recently, the literature has been enriched with papers describing the osteopathic treatment efficacy in reducing constipation. Emerging literature reported the efficacy of OMT in reducing constipation symptoms and improving QoL in typically developed people, as well as in children with disability. The present study aims to evaluate the efficacy of a specific OMT for managing chronic constipation in people with RTT and its impact on primary caregivers' quality of life. Research questions:

  • Can an OMT improve the constipation of people with RTT, increasing the frequency of bowel movements?
  • Can the effects of an OMT aimed at reducing the constipation symptoms in people with RTT positively impact the participants' parents' constipation-related QoL? Twelve individuals with RTT and their families will be recruited to participate in this single-blind parallel group-randomized study. Participants will be randomly divided into an experimental group (EG) and a control group (CG). After the preliminary evaluations, each participant will undergo eight OMT carried out weekly for eight weeks. The OMT will aim to facilitate bowel movements by increasing blood flow through the abdomen. At the end of the treatment, the participants will repeat the evaluation conducted before the OMT, and the collected data will be analyzed.

Outcome Measures

Primary Outcomes (10)

  • Change in number of evacuations

    The number of participants' evacuations collected daily by participants' caregivers

    Every day, for one week, immediately before the intervention phase.

  • Change in number of evacuations

    The number of participants' evacuations collected daily by participants' caregivers

    Every day, during the intervention phase (for 8 weeks).

  • Change in number of evacuations

    The number of participants' evacuations collected daily by participants' caregivers

    Every day, for one week, immediately after the end of the intervention phase.

  • Change in number of enemas and medications

    The number of enemas and medication provided to the participants' to simplify or induce the evacuations collected by their caregivers.

    Every day, for one week, immediately before the intervention phase.

  • Change in number of enemas and medications

    The number of enemas and medication provided to the participants' to simplify or induce the evacuations collected by their caregivers.

    Every day, during the intervention phase (for 8 weeks).

  • Change in number of enemas and medications

    The number of enemas and medication provided to the participants' to simplify or induce the evacuations collected by their caregivers.

    Every day, for one week, immediately after the end of the intervention phase.

  • Change in the Modified Constipation Assessment Scale (m-CAS)

    The m-CAS is an eight-item scale that measures whether constipation is present and its intensity. A higher score represents more severe constipation. Cronbach α coefficient showed good internal consistency over time (α\>0.70). The Pearson product-moment correlation coefficient was used to evaluate test-retest reliability and showed evident acceptance (r=0.93; P\<0.001).

    15 minutes. Before the treatment initiation (T0) and after the treatment end (T1 - after 8 weeks from T0).

  • Change in theConstipation Scoring System (CSS)

    The CSS assesses the severity of constipation with a maximum score of 30 (0 = no constipation, 30 = severe constipation. The scale was initially validated with a 100-subject sample and could correctly detect the absence or presence of constipation in 96% of the subjects, thus representing a sensitive and valid tool.

    15 minutes. Before the treatment initiation (T0) and after the treatment end (T1 - after 8 weeks from T0).

  • Change in theConstipation-Related Quality Of Life (CRQOL)

    The CRQOL assesses quality-of-life domains affected by constipation. It includes four domains: social impairment, distress, eating habits, and bathroom attitudes. In our study, the primary caregiver filled this scale reporting his feelings concerning the participant's constipation management. The internal consistency of each of the four domains was higher than 0.70 using Cronbach's alpha. Excellent test-retest reliability was demonstrated (α\>0.85).

    15 minutes. Before the treatment initiation (T0) and after the treatment end (T1 - after 8 weeks from T0).

  • Change in the Short Form Health Survey-12 (SF-12)

    The SF-12 is a multidimensional measure of health-related quality of life widely used in clinical trials. The SF-12 was administered to participants' primary caregivers. The Italian version of the SF-12 was validated on a large sample of Italian people showing strong psychometric proprieties.

    15 minutes. Before the treatment initiation (T0) and after the treatment end (T1 - after 8 weeks from T0).

Secondary Outcomes (4)

  • Change in the tissue tension

    15 minutes. Before the treatment initiation (T0) and after the treatment end (T1 - after 8 weeks from T0).

  • Change in the abdomen palpability

    15 minutes. Before the treatment initiation (T0) and after the treatment end (T1 - after 8 weeks from T0).

  • Change in the abdominal bloating

    15 minutes. Before the treatment initiation (T0) and after the treatment end (T1 - after 8 weeks from T0).

  • Change in the sacral pad swelling

    15 minutes. Before the treatment initiation (T0) and after the treatment end (T1 - after 8 weeks from T0).

Data Sharing

IPD Sharing
Will share

The investigators plan to share the anonymized IPD related to participants' age, and levels of Rett syndrome severity, motor functioning, and daily physical activity. The information will be published as a part of the scientific articles produced after the study ends.

Time Frame
The IPD will be available if and when scientific articles related to this study are published. Should the data be published, they will be available indefinitely in the scientific literature.
Access Criteria
The investigators plan to submit scientific articles related to the present study to be published in an open access peer-review scientific journal. Therefore, if the articles are published, the data will be available on the website of the journal in which they were published.
