Animal-assisted occupational therapy to boost brain signal complexity in minimally conscious adults
Official title: Neurological and Physiological Effects of Animal-assisted Therapy for Patients in a Minimally Conscious State: a Randomized, Controlled Cross-over Study
Run by University of Basel · NCT06931665 · Data updated 2026-11-12
We will try animal-assisted occupational therapy to see if it increases brain signal complexity in adults who are in a minimally conscious state.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) with acquired brain injury who meet minimally conscious state criteria, are physiologically stable in an inpatient setting, and have consent from a legal representative are ideal candidates.
✕Probably not a fit
Patients with animal phobias or allergies, unstable medical conditions, or recent major medication changes are excluded and unlikely to benefit from this intervention.

What this trial studies
This interventional study delivers animal-assisted occupational therapy sessions to inpatients with a minimally conscious state and records brain and physiological signals. Researchers will measure EEG entropy as the primary neural outcome, alongside ECG, electrodermal activity, and behavioral observations. Participants are adults with acquired brain injury who meet CRS-R criteria for MCS and are physiologically stable, with consent from a legal representative. The study is conducted at REHAB Basel and the neurorehabilitation service at Geneva University Hospitals.
Why it matters
Potential benefit: If successful, the approach could increase measures of brain complexity and possibly support recovery-related changes in consciousness and responsiveness.
How similar studies have gone: Small pilot and case studies have reported behavioral responses to animal-assisted interventions in disorders of consciousness, but robust evidence using EEG entropy is limited and this application is relatively novel.
