The Role and Benefits of Physical Therapy Following Sport-Related Concussions

Context: Sport-related concussion management often requires referral to physical therapy (PT).

Objectives: To (1) outline the role of PT in the management of sport-related concussion, (2) describe patients who underwent PT, and (3) discuss outcomes of athletes who underwent PT.

Design: Retrospective cohort study.

Setting: Single institution.

Methods: Adolescent athletes aged 14-19 years old who sustained a sport-related concussion from November 2017 to April 2022 were evaluated. The cohort was dichotomized into 2 groups: PT versus no PT. The outcomes were days from initial PT visit to symptom resolution (SR) and return-to-play. Subgroup analyses compared recovery metrics between those initiating PT before and after 30 (1 mo) and 90 days (3 mo) of injury. A univariable and multivariable regression was used to determine predictors of recovery.

Results: Of 1010 concussed athletes, 205 (20.3%) received referral for rehabilitation, and 58 (28.3%) patients received PT at the parent institution. Those who received PT had a higher number of prior concussions compared with those who did not (PT: 1.0 [1.2]; non-PT: 0.6 + 1.0; χ2 = 19.37, P = .007). A large proportion of PT recipients reported headache (n = 45, 81.0%); visual disturbances (n = 32, 65.5%); and vestibular (n = 37, 63.8%), cervical (n = 25, 43.1%), or oculomotor dysfunction (n = 25, 43.1%). Most patients received exertional therapy (n = 32, 55.1%), vestibular therapy (n = 31, 53.4%), and/or cervical therapy (n = 30, 51.7%). Those initiating PT before 1 and 3 months had significantly shorter median times to SR compared with those initiating after 1 and 3 months, respectively. Multivariable regression showed that a shorter time between injury and the initial PT visit was predictive of faster SR (β = 1.66, P = .048).

Conclusions: Headache, dizziness, and visual disturbances were commonly reported symptoms by patients who received PT. Cervical, vestibular, and oculomotor deficits were common objective findings by physical therapists, and cervical, vestibular, and exertional therapy were common interventions. Delayed time to PT was independently associated with a longer time to SR.
