About this trial

Patients evaluated at Penn Presbyterian Medical Center for traumatic brain injury (TBI), who sign the informed consent, will undergo assessment of electrophysiologic potentials evoked by transcranial magnetic stimulation (TMS), using the Delphi-MD device (QuantalX Neuroscience Ltd., Saba Israel).

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Age 18 years and older

Evidence of mechanical energy impacting the head or inertial forces affecting the head

Trauma-related abnormality on CT scan on admission

If CT normal, documented/verified TBI based on evidence of either loss of consciousness, post-traumatic amnesia, confusion, or post-traumatic symptoms.

Disqualifiers

History of disabling pre-existing neurologic disease (Such as epilepsy, brain tumors, meningitis, cerebral palsy, encephalitis, brain abscesses, vascular malformations, cerebrovascular disease, Alzheimer's disease, multiple sclerosis, or HIV-encephalitis)

History of premorbid disabling condition that interfere with outcome assessments

Bilaterally absent pupillary responses

Penetrating traumatic brain injury

Trial population

We will enroll up to 145 patients with a traumatic brain injury diagnosis evaluated at University of Pennsylvania Health System over 5 years. We will also evaluate up to 70 uninjured healthy controls, matched by age and gender to TBI participants.

Time perspective

Prospective

Treatments tested in this trial

  • Delphi-MD device (QuantalX Neuroscience Ltd., Saba Israel)

    Device

    Delphi-MD utilizes the use of transcranial magnetic stimulation evoked electroencephalography (TMS-EEG) for diagnostic purposes in a wide range of neurological disorders. Delphi-MD includes a magnetic stimulator and coil, an EEG amplifier and electrode cap and software for the acquisition and analysis of the data. Delphi-MD stimulation protocol includes low intensities (sub motor thresholds) and frequencies over six stimulation sites (bilateral primary motor cortex, and bilateral dorsolateral prefrontal cortex).

Treatment groups

215 Participants
are divided into 2 treatment groups
Group A: Traumatic Brain Injury (Acute, Subacute, Chronic)1 intervention
Group B: Healthy Control1 intervention

Trial outcomes

Primary outcomes

1

1. Differentiate between healthy controls and TBI participants in measured outputs of the DELPHI-MD device (WFA, STP, EPD, LPD, and Connectivity)

1. WFA (Waveform Adherence) 2. STP (short-term plasticity) 3. EPD (Early Phase Deflection) 4. LPD (Late Phase Deflection) 5. Connectivity (these are all in arbitrary units)

Time frame
Day 1
2

2. Correlate DELPHI-MD outputs with neural deficits identified through patient reported and clinician reported outcome measures

For single timepoint (day 1).
