What is the purpose of this trial?

Given the rising rates of concussion in youth ages 10-19 and the significant proportion of young people who remain symptomatic for months following concussion, research evaluating the efficacy of multifaceted treatment options following concussion is imperative. Studies examining the efficacy of treatment strategies following concussion in children and adults are surprisingly limited, and most focus on one treatment approach, have small sample sizes, are not randomized controlled trials, and focus on individuals with prolonged recovery (months). There is a need for a multifaceted treatment trial to examine the early implementation of treatment approaches that may reduce prolonged recovery while considering the heterogeneous presentation of symptoms and patient preferences in the sub-acute stage following concussion. Randomized controlled trials that consider a multifaceted transdisciplinary approach to treatment in the early period following concussion are needed to raise the bar regarding evidence-informed management following concussion

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is the multimodal or symptom-specific treatment for concussion safe for humans?

Research indicates that treatments involving physical therapy and multidisciplinary care for concussion, including neck treatment and symptom-specific approaches, are generally safe. Participants in studies reported improvements in symptoms like headache, dizziness, and neck pain, although some experienced recurrent symptoms over time. ^{1 2 3 4 5}

How is the Multimodal vs Symptom-Specific Treatments for Concussion unique compared to other treatments?

This treatment is unique because it combines multiple approaches, such as physical therapy, vestibular rehabilitation, and symptom-specific treatments for dizziness, neck pain, headaches, and sleep disturbances, to address the diverse symptoms of post-concussion syndrome. This comprehensive, multidisciplinary approach aims to improve recovery by targeting the specific needs of each patient, unlike standard treatments that may focus on only one aspect of the condition. ^{1 3 5 6 7}

What data supports the effectiveness of the treatment for concussion?

Research suggests that a multimodal approach, including physical therapy and neck treatment, can help manage symptoms like headache, dizziness, and neck pain in people with persistent post-concussion symptoms. Studies indicate that these treatments can improve or sustain symptom relief over time, although some symptoms may recur. ^{1 3 5 7 8}

Exclusion Criteria

I currently have active cancer.

Inability to provide informed consent

I do not have uncontrolled rheumatologic, inflammatory, or neurologic disorders, fibromyalgia/chronic fatigue syndrome, coagulopathy, or immunosuppression.

What Are the Treatments Tested in This Trial?

Interventions

• Generic Concussion Treatment
• Symptom-specific Dizziness &/or Neck Pain Treatment
• Symptom-specific Headache Treatment
• Symptom-specific Sleep Disturbance Treatment

Trial Overview This trial tests multiple treatments for concussions in youth. It's looking at how effective different symptom-specific approaches are when started early after injury. The study uses randomized controlled methods meaning participants are randomly assigned to treatment groups without choosing which one they receive.

How Is the Trial Designed?

Group I: Multimodal Treatment Experimental Treatment 1 Intervention

The multimodal treatment consists of 6 treatment sessions that will combine basic physiotherapy exercises to address dizziness and balance problems, training in deep breathing, progressive muscle relaxation, visualization to address headache, sleep hygiene education to address insomnia, and cognitive-behavioral intervention and gratitude exercises to promote coping and resilience. The treatment is designed to be implemented by a variety of clinical health care professionals.

Group II: Headache Treatment Experimental Treatment 2 Interventions

Participants in the headache arm will be randomized to receive a peripheral, greater occipital nerve block with 0.5% Bupivacaine or the multimodal treatment protocol. Participants will complete a daily headache diary over the 6-week treatment period, following a link on their mobile device. Patients receiving a nerve block will have weekly over-the-phone or virtual check-ins by the study team to evaluate for any side effects, pain, as needed medications, and study compliance. These patients will be given supplemental HA education as needed. Participants receiving the block will be offered a second block at 6 weeks if they meet the following criteria: a. no side effects with the first block, b. participant received relief from the first block and prefers a second, and c. headache is still occurring at least once per week. Participants randomized to the multimodal treatment portion, will have up to 6 weeks of scheduled multimodal treatment sessions.

Group III: Dizziness and/or Neck Pain Treatment Experimental Treatment 2 Interventions

Participants will be randomized to receive cervicovestibular physiotherapy (CV PT) or the multimodal treatment program. The CV PT group will participate in a combination of cervical spine and vestibular rehabilitation as per a standardized treatment algorithm based on individual assessment findings for six weeks. This form of therapy combines treatment techniques for both the cervical spine and vestibular system that are commonly used in physiotherapy practice. Cervical spine treatments may include neuromotor retraining, sensorimotor retraining, manual therapy, soft tissue techniques, and range of motion exercises. Vestibular rehabilitation may include gaze stabilization, habituation, standing balance, and dynamic balance.

Published Research Related to This Trial

In a study of 11 individuals with persistent concussion symptoms, neck treatment as part of multidisciplinary care led to sustained improvements in post-concussion symptoms over 6 and 12 months.

While most participants found neck treatment beneficial for their recovery, 7 out of 11 reported recurring headaches, neck pain, or dizziness, indicating that while neck treatment is helpful, some symptoms may persist long-term.

Postconcussion syndrome (PCS) is a complex condition with symptoms that can persist for months or years, and it can be divided into early-phase and late-phase posttraumatic disorders, influenced by various psychosocial factors.

Effective treatment for PCS requires a careful diagnosis of symptoms and comorbid conditions, with a recommended approach that includes managing treatable symptoms and incorporating guided aerobic exercise to aid recovery.

Whiplash and concussion can present with similar symptoms, such as neck pain and dizziness, which may lead to misdiagnosis; therefore, integrating guidelines for both conditions could improve patient outcomes.

In a study of three cases, patients showed significant improvement in daily activities and reductions in symptoms after receiving multidisciplinary management that addressed both whiplash and postconcussion syndrome, highlighting the need for comprehensive assessment and treatment strategies.

A new treatment-based profiling model has been proposed to assist physical therapists in managing patients after a concussion, focusing on symptom type, intensity, and movement response.

The model emphasizes three key treatment areas: symptom management, movement system optimization, and performance optimization, which can help therapists make informed decisions tailored to individual patient needs.
