NCT04306601

Brief Summary

Low-intensity focused ultrasound can be effective in severe TBI patients with disorder of consciousness. This study is a prospective single arm, open-label and explorative clinical trial to evaluate the therapeutic effect of recovery from DoC and safety of low-intensity focused ultrasound stimulation at thalamic area in patients with post-traumatic DoC.

Outcome Measures

Primary Outcomes (3)

  • Clinical evaluation

    Coma Recovery scale - Revised The CRS consists of 25 hierarchically arranged items that comprise 6 subscales addressing auditory, visual, motor, oromotor, communication, and arousal processes. Scoring is based on the presence or absence of specific behavioral responses to sensory stimuli administered in a standardized manner. The lowest item on each subscale represents reflexive activity, whereas the highest items represent cognitively mediated behaviors. The total minimum and maximum values are 0 and 23.

    6 weeks

  • Quantitative electroencephalography

    Weighted phase lag index

    2 weeks

  • Resting state functional MRI

    ALFF (amplitude of low-frequency fluctuation)

    2 weeks

Secondary Outcomes (4)

  • Adverse reaction

    2 weeks

  • Rancho Los Amigos Levels of Cognitive Functioning Scale (LOCF)

    6 weeks

  • Glasgow Coma Scale

Eligibility Criteria

Age19 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age is 19 years or higher
  • The patient was diagnosed with traumatic brain injury
  • A patient 6 months after brain damage
  • A patient was diagnosed with unwakefulness syndrome or minimally conscious state

You may not qualify if:

  • The patient needs changes of drugs that can affect changes in consciousness during the study's participation.
  • The drugs listed below are not allowed to be used in combination, unless they are being taken stably from 4 weeks prior to screening.
  • Benzodiazepines
  • Anti-epileptic drugs
  • Selective serotonin reuptake inhibitor
  • Opioids
  • Cardiopulmonary resuscitation was performed on the patient for more than 10 minutes
  • The patients has uncontrolled seizure.
  • The patient has severe thalamic atrophy of both sides, and it is impossible to determine the target area to be stimulated by sonication
  • The patient has severe medical conditions which can affect the consciousness
  • In brain computed tomography, calcification or foreign object (metallic materials, shunt catheter, etc.) that affects sonication are found in brain or skull.
  • In brain MRI, an abnormal brain blood flow or blood vessel is found
  • The patient is pregnant
