This page contains current research articles on concussions in sports and up-to-date information on post-concussion syndrome.
Post-concussion syndrome involves a subset of patients who are experiencing symptoms beyond expected healing rates.
The World Health Organization defines PCS as a persistence of 3 or more of the following after head injury:
On the left are some research articles involving new methods for resolving post-concussion syndrome.
This study measures the effect that cervical spine and vestibular rehabilitation has on a patient with persistent concussion symptoms.

This study was designed to evaluate the efficacy of subsymptom exercise training for those with a post-concussion symdrome diagnosis.

This review of the research will assist practitioners on how to rehabilitate patients who have suffered concussions, as well as those who are not progressing past some symptoms. Having reviewed research from 1966 to 2011, it shows what has been effective thus far in reducing symptoms and getting patients back to normal function.
This article discusses the effect of exercise training on participants after a post-concussion syndrome diagnosis and their ability to return to normal physiological function, including autonomic balance and the improvement of cerebral blood flow autoregulation.
