Brief Summary:

Pulsed Electromagnetic Field (PEMF) Reduction of CSF and Serum Biomarkers After Traumatic Brain Injury (TBI).

The primary objective of this pilot study is to determine whether PEMF treatment (PEMF+) reduces the magnitude and duration of the increase in CSF and blood biomarkers after traumatic brain injury (TBI) compared to a PEMF untreated (PEMF-) group. Values in both groups are compared to uninjured brain CSF and blood biomarker levels obtained from hydrocephalus patients undergoing ventriculo-peritoneal shunt placement. A secondary objective of this pilot study is to determine whether PEMF treatment improves the physiologic status of the brain as evaluated by brain tissue monitors of thermal dilution cerebral blood flow (CBF), intracranial pressure (ICP), and tissue PO2 (PbtO2). Improved physiologic status would be reflected by increased CBF, PbtO2, and reduced ICP. Improved physiologic status may also be inferred from derived variables reflecting improved cerebrovascular and intracranial pressure autoregulation.

A tertiary objective of this pilot study is to obtain preliminary data on the relationship between the time course and magnitude of post-TBI CSF and blood biomarker levels as they relate to three month outcome by Glasgow outcome score extended (GOSE) and modified Rankin Score (mRS).


Condition or disease Intervention/treatment Phase
Traumatic Brain Injury Device: SofPulse Not Applicable

Detailed Description:

Investigators will enroll a total of 45 subjects, 30 after TBI and 15 patients with hydrocephalus having ventriculo-peritoneal shunts inserted. It is anticipated that in order to enroll 30 TBI participants investigators will need to screen approximately 50 subjects; and for the patients undergoing ventriculo-peritoneal shunt placement we will need to screen 30 patients in order to enroll 15. Of the 30 TBI patients, 15 will have PEMF+ and 15 will have PEMF-. PEMF+ means that the device will be in place and will be on, PEMF- means that the device will be in place but will not be turned on.

The study will be double blinded. The honest broker (HB) Dr. Amal Alchbli, will not be involved in the study except to turn on the PEMF device with the indicator light showing when the PEMF device is on , will be hidden from view by tape. The HB will keep a list of the patients treated with PEMF+ or not PEMF- along with their MRN# coded and the start and end times of PEMF treatment during their stay in the NSI. The nurses in the unit will be asked to indicate on the CNS monitor when the PEMF applicators are on or off the patient.

The subjects will participate in this study for up to one week while in the Neuroscience Intensive Care Unit (NSI). There will also be follow up on secondary clinical outcome measures at discharge, one and three months post discharge. The one and three month follow ups will be conducted over the phone.

The duration of enrollment is expected to be two years. The estimated date for the investigators to complete this study (complete primary analyses) is 3.0 years.

The estimated time for data retention is 5 years.

Arm Intervention/treatment
Experimental: SofPulse active
SofPulse active group. Patients who will be treated with the SofPulse activated on their heads for up to seven days in intensive care or as long as they are in the unit The PEMF device is kept on throughout and provides a 15 min pulsed treatment every hour.
Device: SofPulse
SofPulse PEMF device treatment of the brain after traumatic injury

Placebo Comparator: SofPulse inactive
SofPulse inactive. The SofPulse will be placed on the patient's head but not activated for as long as they are in intensive care.
Device: SofPulse
SofPulse PEMF device treatment of the brain after traumatic injury

Sham Comparator: Normal pressure hydrocephalus
CSF and serum samples from 15 normal pressure hydrocephalus patients will be used to compare CSF and serum biomarker levels in the 30 TBI patients.
Device: SofPulse
SofPulse PEMF device treatment of the brain after traumatic injury




Primary Outcome Measures :
  1. CSF and serum biomarkers [ Time Frame: CSF and serum collection from Zero to 7 days after injury ]
    CSF and serum biomarkers: Magnitude of increase and rate of decrease in patients treated with SofPulse active and Sofpulse inactive and both compared to CSF and serum biomarkers in control normal pressure hydrocephalus.


Secondary Outcome Measures :
  1. Glasgow Coma Score [ Time Frame: Admission, daily for 7 days, discharge from hospital and one and three months ]

    Coma severity based on Eye (4), Verbal (5), and Motor (6) criteria. Best Eye Response Eyes open spontaneously+4 Eye opening to verbal command+3 Eye opening to pain+2 No eye opening+1 Not assessable (Trauma, edema, etc)C

    Best Verbal Response Oriented+5 Confused+4 Inappropriate words+3 Incomprehensible sounds+2 No verbal response+1 IntubatedT; Best Motor Response Obeys commands+6 Localizes pain+5 Withdrawal from pain+4 Flexion to pain+3 Extension to pain+2 No motor response+1


  2. Glasgow Outcome Score Extended [ Time Frame: Admission, daily for 7 days, discharge from hospital and one and three months ]

    The Glasgow Outcome Scale (GOS) is a global scale for functional outcome that rates patient status into one of five categories: Dead, Vegetative State, Severe Disability, Moderate Disability or Good Recovery. The Extended GOS (GOSE) provides more detailed categorization into eight categories by subdividing the categories of severe disability, moderate disability and good recovery into a lower and upper category:

    Table 1: Extended Glasgow Outcome Scale (GOSE) Use of the structured interview is recommended to facilitate consistency in ratings.

    1. Death D
    2. Vegetative state VS
    3. Lower severe disability SD -
    4. Upper severe disability SD +
    5. Lower moderate disability MD -
    6. Upper moderate disability MD +
    7. Lower good recovery GR -
    8. Upper good recovery GR

  3. Modified Rankin Scale [ Time Frame: Admission, daily for 7 days, discharge from hospital and one and three months ]

    0 No symptoms at all

    1. No significant disability despite symptoms; able to carry out all usual duties and activities
    2. Slight disability; unable to carry out all previous activities, but able to look after own affairs without assistance
    3. Moderate disability; requiring some help, but able to walk without assistance
    4. Moderately severe disability; unable to walk without assistance and unable to attend to own bodily needs without assistance
