About this study

Official title: Neurovascular Reactions to Animal-assisted Therapy in Patients With Severe Disorders of Consciousness (DOC): a Randomized-controlled Trial

There is practical evidence but no scientific investigations that persons with severe disorders of consciousness can profit from animal-assisted therapy regarding their level of awareness.

The aim of this study is to investigate the effect of animal-assisted therapy on brain activity of inpatients at REHAB Basel with severe disorders of consciousness.

To do so, the frontal brain activity of 20 the inpatients at REHAB Basel in a minimally conscious state is investigated via near-infrared spectroscopy (NIRS). Moreover, 20 healthy participants are included as control subjects.

Read the detailed description

Each participant will be measured in 6 sessions. Sessions take place three times a week for 2 weeks (leading up to a total of 3 experimental sessions and 3 control sessions), each lasting for about 15 minutes.

Each session consists of 5 phases, with an animal present in three of them. In the beginning, waiting (with no stimulus presented) serves as baseline measurement. Second, an animal is watched, then the animal is placed on the patient's lap and in the fourth condition, the patient can stroke the animal with the help of the present therapist. After, there is again a waiting condition.

Control sessions are comparable sessions but with a fur pet instead of a live animal as stimulus.

Measurements are: brain activity (near-infrared spectroscopy, NIRS), skin conductance (EDA), heart rate and heart rate variability assessed via photoplethysmography (PPG) during the sessions and the BAVESTA score after each session. For further behavior analysis all sessions are videotaped.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Near-infrared spectroscopy (NIRS): oxygenated hemoglobin (O2HB), deoxygenated hemoglobin (HHB), total hemoglobin (HB) and blood oxygen saturation (O2Sat)

    All parameters are measured in mmol/ml throughout the sessions, measured via NONIN SenSmart

    Measured: 2 weeks

Secondary outcomes (1)
  1. Galvanic Skin Response

    GSR is measured throughout the sessions via ERPrec, an EEG and ERP recording Software. Skin conductance is measured in μmho.

    Measured: 2 weeks

Questions about this trial

What is this clinical trial studying?

A study testing animal-assisted activity in people with Consciousness Disorder and Brain Injuries, run by Swiss Tropical & Public Health Institute at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Near-infrared spectroscopy (NIRS): oxygenated hemoglobin (O2HB), deoxygenated hemoglobin (HHB), total hemoglobin (HB) and blood oxygen saturation (O2Sat) (time frame: 2 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Sep 2021.
