Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention group Concussion Essentials (CE) will receive up to 8 weeks (8 scheduled, 1 hour sessions) of an individualised multimodal intervention, provided by trained clinicians. CE incorporates three modules designed to treat symptoms within the key PPCS clusters: common, physical, psychological. For each module, treatment procedures will be clearly detailed and manualised to ensure consistency.
1. Concussion essentials module: Participants will receive education and advice addressing symptoms commonly experienced by children with PPCS.
2. Physical module: Participants will receive treatment comprising vestibular, ocular-motor and cervical treatment, and supported graded return to aerobic exercise delivered by a clinician under supervision of a neurophysiotherapist experienced in concussion management.
3. Psychological module: Participants will receive evidence-based cognitive behaviour therapy (CBT), the Creating Opportunities for Personal Empowerment (COPE) program, adapted for concussion, and targeting emotional symptoms (anxiety, depression, avoidance), delivered by a clinician or clinical psychology student supervised by an experienced psychologist.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation to CE or or UC will be in a 1:1 ratio. In order to ensure that PCS profiles are similar in each of the treatment groups, prior to randomisation, participants will be stratified by age and sex (3 age-groups). These groups will be randomised separately to CE or UC. The randomisation sequences will be computer-generated with variable block sizes, in order to reduce the risk of allocation bias. The study statistician will have no contact with the participants.

Efficacy
Statistical methods / analysis
The primary outcome is the proportion of participants with delayed recovery, at, or prior to completion of, intervention. Participants will be considered fully recovered if there is less than or equal to 1 difference in severity for all items on the PCSI-P, compared to pre-injury PCSI-P ratings. Our data suggests that a 46.6% reduction in symptomatic children occurs from 4 weeks post-injury to 3 months. To establish effectiveness of the trial, we would expect to observe at least a 50% decrease in those with delayed recovery (46.6% UC vs 23.3% CE). With a 90% power and 5% error level, we would require a total sample size of 172, with two equal groups of 86. Our data also indicates an expected loss to follow up of 20%, and so we will aim to recruit 216 participants. With data on 86 per group, we will have 90% power to find a difference of ~0.4SD on secondary continuous outcomes (incl. PCSI domains, PedsQL, CHU-9D, common, physical and psychological function outcomes), and ~23% absolute difference between groups in the percentage who return to school/sport.

Summary
Brief summary
By age 10, 1 in 5 children (~51,000 Australian children) will sustain a concussion and present with post-concussive symptoms (PCS) requiring medical treatment. Many children and youth recover rapidly from these symptoms and are symptom free and returned to pre-injury activities within 4 weeks. In contrast, ~40% of children suffer ‘persisting PCS’ (PPCS), defined as 2 or more PCS lasting more than 4 weeks. This group of children have limited tolerance for routine academic, sport/leisure and social activities and are unable to return safely to these activities. Despite their debilitating impact, intervention trials addressing PPCS in children are lacking. We propose a randomised trial of a novel multimodal intervention to reduce the burden of debilitating PPCS for the ~40% of children who experience delayed recovery after concussion. Participants with PPCS at 2-3 weeks post-injury will be recruited and randomised to either active (CE) or usual care (UC) interventions, which will be delivered over up to 8 sessions between 4 – 12 weeks post-injury. The primary aim of the CE is to reduce the number and severity of PPCS. We propose the following hypotheses:

Hypothesis 1: Compared to the UC, children in the CE will have a clinically significant reduction in number and severity of PPCS by treatment completion

Hypothesis 2: Compared to the UC, children in the CE intervention will have a significantly higher proportion of children who, at treatment completion, have:
2.1 Demonstrated reduction in PPCS across all clusters: generic, physical, psychological
2.2 Returned to normal activity (school, sports, leisure activities)
2.3 Improved physical and psychosocial quality of life
2.4 Lower rate of utilisation of health services
