Sport-related Concussion Brain Concussion Healthy | Other: high-intensity neck strengthening Other: Control group | Not Applicable |
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 72 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Masking: | Triple (Participant, Investigator, Outcomes Assessor) |
Masking Description: | Neither subjects nor the study team members responsible for performing the laboratory- or radiology-based assessment will be informed of group allocation status, although subjects will be aware of whether or not they are performing neck strengthening exercises during their exercise sessions. Subjects will be instructed not to reveal their group status during subsequent assessment sessions. |

Arm | Intervention/treatment |
---|---|
Experimental: high-intensity neck strengthening group |
Other: high-intensity neck strengthening
All subjects will exercise 2 days per week for 12 weeks under the direct supervision of a study-assigned strength coach with a minimum of 1 day of rest between exercise sessions. Participants will perform a standardized set of general resistance exercises targeting the chest, shoulders, back, upper and lower extremities, and core. Additionally, they will also perform a higher number of repetitions of manual resistance neck strengthening exercises in sagittal plane flexion and extension, coronal plane lateral flexion in both directions, and axial plane rotation in both directions,as well as dumbbell shoulder shrugs. |
Control group |
Other: Control group
All subjects will exercise 2 days per week for 12 weeks under the direct supervision of a study-assigned strength coach with a minimum of 1 day of rest between exercise sessions. Participants will perform a standardized set of general resistance exercises targeting only the chest, shoulders, back, upper and lower extremities, and core, without resistance exercises specifically targeting the neck. |

Exclusion Criteria:
- Prior history of trauma-induced neck injury of sufficient severity to require treatment by a medical provider within 30 days of injury or to limit sport participation for > 1 day (note: having received routine chiropractic treatment in the absence of a recent traumatic injury to the neck will not be considered to meet this criterion)
- Any prior history of whiplash injury, stinger/burner, or cervical radiculopathy diagnosed by a medical provider
- Any prior history of bone, disk, neural, or ligamentous abnormality identified on cervical spine medical imaging performed for any reason that is felt by the PI (or designee) to present a risk to study participation
- Any prior history of surgery involving the cervical spine (note: having undergone non-spine surgery to the soft tissue structures in the neck will not necessarily exclude participation, but will be considered on a case-by-case basis by the PI, or his designee, with consultation from the performing surgeon when deemed appropriate)
- Self-report of moderate or severe neck pain (rated as 5 or greater on a 10-point pain scale) lasting > 1 day in the previous 6 months that required any evaluation or treatment by a medical provider or that limited sport participation for > 1 day (note: having received routine chiropractic treatment in the absence of moderate-severe neck pain will not be considered to meet this criterion)
- Self-report of low back pain (any severity) associated with morning stiffness occurring 30 days or more in the previous 3 months.
- Prior episode(s) of unexplained upper extremity numbness, tingling, or weakness suspicious to the PI, or designee, for a stinger/burner or cervical radiculopathy in the last 3 years
- Prior history of concussion in the previous 6 months diagnosed by a medical provider or suspected by the subject, or the parent/guardian of a minor (if no medical evaluation was sought), or any diagnosed/suspected concussion without full recovery and clearance to resume unrestricted sport participation.
- Personal history of migraine headaches within the previous 3 years diagnosed by a medical provider, with one or more headache episodes, or requiring treatment.
- Personal history of anxiety disorder diagnosed by a medical provider that has either been difficult to control, affected daily function, or required treatment with medication or counseling within the previous 3 years.
- Parental/guardian known history of anxiety disorder diagnosed by a medical provider that has either been difficult to control, affected daily function, or required treatment with medication or counseling within the previous 3 years.
