Concussion Post Syndrome Clinical Trial
Official title:
The Effect of Sleep and Slow Wave Enhancement on Recovery From a Concussion in Children and Adolescents: A Longitudinal, Randomized, Double-Blind, and Sham-Controlled Study
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.
In total, 120 participants are planned: 60 patients (30 intervention, 30 sham) and 60 controls (30 intervention, 30 sham). This was estimated from a power analysis and based on previous results. Patients are recruited from the University Children's Hospital Zurich. At first, the participants will complete a baseline assessment of neuropsychological measures (cognitive tests and questionnaires). After completion of the baseline assessment, the participants receive deep sleep enhancement with auditory stimulation for seven nights, but half of them will only receive sham stimulation (device application, but no stimulation). Additionally, they wear an actigraph throughout the whole week. Afterwards, they fill in again some questionnaires (intermediate assessment). One month after study inclusion, the first follow-up will take place where neuropsychological and (optionally) neurological measures will be collected. The second follow-up takes place six months after study inclusion and involves again filling in questionnaires about post-concussive symptoms. The study will be monitored regularly in terms of data validation and source data verification. Adverse events and device deficiencies are carefully documented and reported according to the guidelines of swissmedic and the responsible ethics committee. ;
