Clinical Trial Summary

Concussions affect thousands of Canadians every year. Although the effects are usually temporary, 10-15% of adults experience persistent symptoms likely to last several weeks or even months. It is suggested that nutritional interventions should be considered in concussion management because nutrition can act on several mechanisms of brain injury. However, to date, no study has assessed the impact of dietary interventions on the recovery of people with persistent post-concussive symptoms.

This randomized controlled trial aims to determine the impact of a dietary and nutritional intervention on the physical, cognitive, behavioural and emotional symptoms of patients with persistent post-concussive symptoms in New Brunswick, Canada. Patients will be randomized to one of three groups: 1) dietary treatments and nutritional supplements (experimental group A), 2) nutritional supplements (experimental group B), and 3) physiotherapy treatments (control group). Patients in group A will receive four consultations with a dietitian over eight weeks, in addition to conventional physiotherapy treatments. These patients will receive nutritional counselling and omega-3, vitamin D and creatine supplements. Patients in group B will be prescribed the same supplements as those in group A by their doctor and receive physiotherapy treatments. Finally, patients in the control group will only receive physiotherapy treatments. Patient symptoms will be measured using a questionnaire constructed from tools commonly used in practice. This questionnaire will be completed at the first physiotherapy session and 2, 4 and 8 weeks after the start of the intervention.

Description:

Concussions affect thousands of Canadians every year. Although the effects are usually temporary, 10-15% of adults experience persistent symptoms likely to last several weeks or even months. Some studies have explored the impact of pharmaceuticals on treating post-concussive symptoms. Still, these have shown little success, leading the scientific community to consider multidisciplinary approaches to treating and managing concussions. Recently, it has been suggested that nutritional interventions should be considered in concussion management because nutrition can act on several mechanisms of brain injury. Some nutritional supplements have shown beneficial effects on the speed of recovery and the degree of severity of symptoms related to moderate or severe head trauma. Other studies have shown a link between malnutrition and low neurological and cognitive scores. However, to date, no study has assessed the impact of dietary interventions on the recovery of people with persistent post-concussive symptoms.

This randomized controlled trial aims to determine the impact of a dietary and nutritional intervention on the physical, cognitive, behavioural and emotional symptoms of patients with persistent post-concussive symptoms in New Brunswick, Canada. Patients will be randomized to one of three groups: 1) dietary treatments and nutritional supplements (experimental group A), 2) nutritional supplements (experimental group B), and 3) physiotherapy treatments (control group). Patients in group A will receive four consultations with a dietitian over eight weeks, in addition to conventional physiotherapy treatments. These patients will receive nutritional counselling and omega-3, vitamin D and creatine supplements. Patients in group B will be prescribed the same supplements as those in group A by their doctor and receive physiotherapy treatments. Finally, patients in the control group will only receive physiotherapy treatments. The use of three groups will help determine the individual impact of dietetic treatment offered by a dietitian and the use of supplements. Patient symptoms will be measured using a questionnaire constructed from tools commonly used in practice by medical doctors, physiotherapists and dietitians. This questionnaire will be completed at the first physiotherapy session and 2, 4 and 8 weeks after the start of the intervention.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline in severity of post-concussive symptoms at the end of the intervention	Patients' severity of post-concussive symptoms will be measured using the 5th edition of the Sport Concussion Assessment Tool (SCAT5). This tool assesses the degree of severity of 22 concussion-related symptoms, on a scale of 0 (no symptoms) to 6 (severe). The total number of perceived symptoms is noted by the physiotherapist, and a symptom severity score is calculated (scale from 0 to 132 points).	Baseline and Endpoint (Week 8)
Secondary	Change from baseline in balance at the end of the intervention	The physiotherapist will assess patients' balance using the Modified Balance Error Scoring System (mBESS) test. This objective and validated tool is complimentary to the SCAT5 and is scored from 0 to 30 points, where a greater score indicates severe balance impairment.	Baseline and Endpoint (Week 8)
Secondary	Change from baseline in vestibular ocular motor at the end of the intervention	The physiotherapist will assess patients' vestibular ocular motor using the Vestibular Ocular Screening (VOMS) test (Mucha et al., 2014). This tool measures five domains, including smooth pursuits, saccades (rapid eye movements), near-point convergence, balance vision reflex and visual motion sensitivity. For each domain, the sum of the symptoms is scored, with a total possible score of 0 (no change) to 200 points (significant changes in symptom severity).	Baseline and Endpoint (Week 8)
