Brief Summary:
The HeadSense (HS) HS-1000 device, a new non-invasive brain monitor is expected to safely and accurately monitor concussed patients with minimal discomfort, potentially providing a new modality for concussion measurement. The device is based on advanced signal analysis algorithms that analyze a very low frequency acoustic signal (within the audible range) generated by the device. The acoustic signal is transmitted using a small transmitter, placed in the participant's ear, and picked by an acoustic sensor placed in the other ear.

Detailed Description:

Concussion diagnosis and assessment suffers from lack of a gold-standard measurement, leaving physicians to rely on physical and neurological examinations, neurocognitive/mental status testing, and balance examination, which can be time-consuming and influenced by subjective factors. In order to address this significant drawback, there is a need for novel modalities that diagnose and monitor concussion in a quick easy-to-use and non-invasive manner.

Based on our previous analysis of the physiological processes using acoustic signals that were collected and analyzed so far, our hypothesis is that the HS-1000 is capable of diagnosing and monitoring concussed patients, based on the acoustic raw data derived from the generated acoustic signal along with the analysis of the acoustic signals that derive from the physiological processes in the brain. These processes, e.g. cerebral blood-flow and the respiratory cycle, are impaired during changes in intracranial pressure (ICP) and are hypothesized to change as well once the patient is concussed.

Concussed athletes will be identified through routine visits at the Vanderbilt Sports Concussion Center. Controls will be identified among non-concussed athletes being seen at Vanderbilt Sports Medicine and will be offered participation.

After signing informed consent, both healthy subjects and patients will undergo screening assessments for this study. Eligible patients and healthy subjects will be enrolled into the study and HS-1000 headset portion of the device will be placed in their ears. HS-1000 monitoring intervals will last from 20 minutes continuously. Following completion of data collection, HS-1000 will be removed.

Safety evaluation will include monitoring of adverse events throughout the study.

The study duration for each patient will be up to 1 hour. Healthy subjects will undergo two recordings approximately two weeks apart.

Post-concussion patients will have multiple sessions:

  • Session #1 Baseline recording as soon as possible
  • Session #2 48 hours after session #1
  • Session #3 1 week after session #1
  • Session #4 1 month after session #1

Device: HS-1000 recording



Primary Outcome Measures :
  1. To measure ICP values by using the HS-1000 in healthy subjects and concussed subjects [ Time Frame: 20 minute recording session ]
  2. Determine the correlation between ICP measurements obtained from the HS-1000 device and the clinical findings from the modified Balance Error Score System (mBESS) and ImPACT scores in post-concussion patients. [ Time Frame: 20 minute recording session ]

Secondary Outcome Measures :
  1. To evaluate the ergonomic and functional aspects of using the HS-1000 by having the operators of the device complete a brief 5 question survey about the ease or difficulty in using the device. [ Time Frame: 20 minute recording sessin ]
