Brain Injury, Constipation
Conditions
Brief summary
Empirically patients with acquired brain injury (ABI) are often constipated. This is a major clinical issue. Nevertheless, this has only been sparsely studied. The investigators will measure gastrointestinal transit time (GITT) in 30 patients with ABI, and compare this to healthy controls. Secondly heart rate variability (HRV) is measured in these patients, and associations between HRV and GITT are investigated.

Eligibility
Inclusion criteria
* ABI: * Moderate to severe traumatic brain injury (TBI) (Glasgow Coma Scale (GCS) score 3-12 at admission) * or Stroke * or Anoxic brain injury * Ability to swallow the capsules used to assess GITT * Ability to give meaningful informed consent to participate in the study

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Gastrointestinal transit time (GITT) [in days] | During rehabilitation, when the patient meet the inclusion criteria. This is expected to be between 2 weeks and 4 months after the primary injury. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Association between heart rate variability (HRV) and GITT | During rehabilitation, when the patient meet the inclusion criteria. This is expected to be between 2 weeks and 4 months after the primary injury. | Linear regression with GITT as dependent variable, and high frequency power sepectral density analysis of the heart rate (HF) as the independent variable. |
