Psychogenic Gait Disorder Complicating Recovery After Concussion: A Case Series

Abstract

BackgroundGait impairment is common after concussion. “Dizziness” is associated with prolonged recovery after concussion. Most often each of these symptoms is considered to be of vestibular origin. However, whether or not there are psychological etiologies of gait instability that complicate concussion recovery has been less fully explored. MethodsA chart review was performed of all patients seen between 2017 and 2019 in a weekly pediatric traumatic brain injury clinic. ResultsOf eighty-four patients with traumatic brain injury, five were found to have developed a classic psychogenic gait. All were adolescents at the time of diagnosis. Recognition of this complication led to modification/initiation of physical therapy and/or mental health intervention and eventual resolution for all patients. ConclusionAlthough uncommon, psychogenic gait disorders may complicate concussion recovery in adolescents likely at a higher rate than their occurrence in the general population. This association has not been previously reported. Accurate diagnosis of psychogenic gait likely improves outcomes in this subset of patients with concussion.
