Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A head pulse device will be placed on the participant and a head pulse recording will be obtained. The duration of each recording is approximately 3-5 minutes, with the entire procedure including information gathering taking around 15 minutes.
For concussed participants, these tests will be conducted on game day at the venue that they are competing at.
Self report symptom inventory and neurobehavioural tests including Sport Concussion Assessment Tool (SCAT) questions will be completed and results will be entered into a secure database for analysis.
Concussed participants will be required to be tested daily for two weeks and then 3 times per week in weeks 3 and 4 after the concussion occurring, to measure their recovery.
Trained University Graduates will perform the testing.
Intervention code [1] 322154 0
Diagnosis / Prognosis
Comparator / control treatment
Concussed participants will be measured and results compared with the brain functionality of non-concussed control participants.
The non-concussed participants will be tested 15 times throughout the 6 month study period, with the duration of each recording being 3-5 minutes. These tests will be conducted fortnightly at the training venue.
The Head Pulse recordings of the concussed participants will also be compared to the results of the standard Sport Concussion Assessment Tool (SCAT) test, which are performed by the teams medical staff as part of the diagnostic process in the moments immediately following the injury occurring.

Outcomes
Primary outcome [1] 329495 0
The primary outcome of this interventional study is to document the diagnostic accuracy of the headpulse device for concussion compared to the clinical diagnosis for measurements made following injury.
Participants will have accelerometry measurements and concurrent 3 lead Electrocardiograms, with the main outcome measure being whether a characteristic waveform pattern of cranial accelerometry occurs with participants with concussion.
Timepoint [1] 329495 0
Initial recording of concussed participant taken within 60 minutes of the injury occurring.
Daily recordings taken for 2 weeks following the injury.
3 recordings per week for weeks 3 and 4 following the injury.



Update reports will be prepared and reviewed by the researchers fortnightly, through the study period
Primary outcome [2] 329496 0
A primary outcome of this observational study is to document the brain's recovery from concussion in the days immediately following the injury, when compared to standard neurological clinical testing methods.
The subjective results of the concussed participants SCAT test, which is performed immediately following the injury, and the Symptom Indicator questions which are asked each time a recording is taken, are compared to the objective results obtained from the Head Pulse measurement device. These recordings track the brains recovery in the days following the injury. The recordings are also compared to the cumulative 'normal' readings of the control group (non-concussed participants) to clearly highlight the 'abnormal' readings of concussed participants.
Timepoint [2] 329496 0
Both concussed and non-concussed participants will have multiple sequential recordings taken.
Concussed participants will be measured within 60 minutes of the injury occurring, then daily for the following two weeks. In weeks 3 and 4, three recordings per week will be taken.

Non- concussed participants will be tested fortnightly for a minimum of 15 times throughout the 6 month study period.
Secondary outcome [1] 402785 0
The study will determine the impact that returning to normal physical activity
has on the participants brain's recovery from concussion. Fitbit GPS trackers will be assigned to concussed participants to measure how their Head Pulse recordings are affected by physical activity in the recovery process, which will then be compared to participants who remain sedentary through the recovery period.
Timepoint [1] 402785 0
These recordings will occur through the 30 day post concussion recovery period.

Efficacy
Statistical methods / analysis
This is a feasibility study to see how well we can record the head pulse from healthy participants and participants with concussion. If good quality data is obtained, the aim is to develop a model of head movement in the setting of concussion and recovery from concussion. Head pulse waveforms in each recording session will be normalized to the cardiac cycle to determine its characteristics in the space and frequency domains. Using this information , we will begin to develop an algorithm to categorize known, externally measured variables such as imaging characteristics or brain function characteristics with regard to how these variables align with head movement waveforms. We will compare waveforms obtained in participants with concussion to waveforms obtained in healthy controls.
