About this trial

The prevalence of a traumatic brain injury (TBI) in children and adolescents is around 30% with 70-90% being classified as mild (concussion). Because the brain of a child is still developing, a TBI can have devastating effects and possibly creates lifetime challenges. Sleep seems to play an important role in the post-concussion recovery process. Auditory stimulation during sleep has been shown to reliably boost slow waves, a solid marker for the depth of sleep, and can thus be used to deepen sleep. This study aims to investigate the effects of sleep enhancement via auditory stimulation on recovery after a concussion in children and adolescents in their home. Therefore, half of the patients receive one week of auditory stimulation during deep sleep at their home using a mobile device. The other half follows the same study protocol, but no tones are administered (sham). Cognitive tests as well as symptom questionnaires are used to assess the recovery process. It is hypothesized that the patients in the intervention group will recover better than the ones who haven't received the intervention. Additionally, a group of children and adolescents who never sustained a concussion is included as a control.

Treatments tested in this trial

  • Auditory Stimulation

    Device

    The device records biosignals and precisely plays tones to enhance sleep slow waves.

Trial outcomes

Primary outcomes

1

Cognitive Performance - attention

Assessed by standardized test (normative values).

Time frame
Measured one month after study inclusion.
2

Cognitive Performance - processing speed

Assessed by standardized test (normative values).

Time frame
Measured one month after study inclusion.
3

Cognitive Performance - executive function

Assessed by standardized test (normative values).

Time frame
Measured one month after study inclusion.

Secondary outcomes

1

Subjective recovery

Assessed by standardized symptom questionnaires.

Time frame
Measured at baseline, one week later (intermediate assessment), one month later (follow-up 1) and six months later (follow-up 2).
2

Algorithm performance

The algorithm flags which are produced by the mobile device used for the auditory stimulation (i.e. sleep detection flags, stimulation flags). They are used to investigate the algorithm performance for each subject.

Time frame
Recorded during seven nights of stimulation or sham (intervention week).
3

Neurological outcome

Measured using Magnetic Resonance Imaging (standard structural and hemodynamic imaging, DTI, and susceptibility weighting) to investigate the neurological outcome.

Time frame
One month after study inclusion (follow-up 1).
4

Injury characteristics

Only for patients: Injury characteristics collected from the Hospital Information System that might influence baseline and follow-up measures and their change over time.

Time frame
baseline, pre-intervention

Other outcomes

1

Intervention tolerability

Measured using an intervention evaluation questionnaire (self-designed).

Time frame
After the intervention week (one week after study inclusion).
