Exercise in Postconcussion Symptoms and Posttraumatic Headache

July 7, 2025 updated by: St. Olavs Hospital

Exercise Interventions in Patients With Postconcussion Symptoms and Posttraumatic Headache. A Randomized Controlled Trial.

The goal of this clinical trial is to compare two models of delivery of guided exercise in patients with exercise intolerance after mild head injury.

The main question it aims to answer is:

• Is a program that includes elements of in-house exercise and follow-up sessions, and repeated treadmill testing, superior to a program with telephone-based follow-up only?

Participants will undergo a treadmill test to determine eligibility for the study, and to determine at what intensity level their symptoms worsen (symptom threshold). Thereafter they will exercise 15-20 minutes, 3-5 times per week at 80-90% of the heart rate that was found to be the symptom threshold. One group will receive face-to-face folllow-up and repeated testing, one group will receive telephone-based follow-up only .

Researchers will compare these two groups to see if closer follow-up is superior when it comes to recovery from exercise intolerance after 12 weeks of exercise.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients with self-reported symptom exacerbation in relation to physical activity will be screened for inclusion with Buffalo Concussion Treadmill test (BCTT), an incremental treadmill exercise test according to a standard Balke protocol, to the first sign of symptom exacerbation or submaximal exertion. Heart rate and perceived exertion (Borg scale) are measured every minute. Patients who demonstrate symptom exacerbation according to predefined criteria will receive an individually tailored program for workouts with self-selected aerobic activites, of 15-20 minutes duration, 4-5 times per week at 85-90% (measured with HR monitor) of the HR at test termination, and they are randomised to either:

A. Every week the first three weeks, participants will exercise one individual session at the hospital, and the BCTT will be performed every 3rd week at the hospital to be able to shape the intervention.

B. The participants will only exercise at home, and will be contacted by telephone/video call, every week during the first three weeks, thereafter less often, up to every third week.

After 12 weeks, there will be a repeated BCTT, performed by a blinded assessor.

Patient reported outcomes are collected using electronic questionnaires before and after the intervention and 6 months after inclusion.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Age 18-65 years
  • Having sustained a minimal head injury or mild traumatic brain injury at least 2 weeks ago.
  • At least one postconcussion symptoms, of at least moderate degree, occurring within the first week after the head injury.
  • Intolerance for physical activity (self-reported and measured; including symptom exacerbation later on the test day).
  • Capable of giving informed consent.

Exclusion Criteria:

  • More than 2 years since last injury.
  • The symptoms are better explained by other conditions.
  • Severe communication problems, typically due to poor knowledge of Norwegian.
  • Severe psychiatric, neurological, somatic, or substance abuse disorders that will make it problematic to function in a group and/or will complicate follow-up and outcome assessment.
  • Safety concerns according to the study medical checklist.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Follow-up face-to face

Home-based and in-house exercise, supervised both by telephone and face-to-face.

Every week the first three weeks participants will exercise one session at the hospital, and the BCTT/BCCT will be performed every 3rd week, at the hospital in order to be able to shape the intervention.
Other: Sub-symptom threshold exercise
Aerob exercise at an intensity just below the intensity that provokes symptom exacerbation.
Active Comparator: Follow-up over the phone
Home-based exercise only, supervised by telephone. The participants will exercise solely in the home setting and will be contacted by telephone, every week during the first three weeks, thereafter every third week. Based on the therapist's evaluation during these calls, the intervention is shaped.
Other: Sub-symptom threshold exercise
Aerob exercise at an intensity just below the intensity that provokes symptom exacerbation.
