Comment by Dr. Mladenoff
This study reveals that light aerobic exercise initiated by 7 days post concussion can have a positive influence on reduction of symptoms at 28 days.
No pre and post physical examinations were performed, there is no discussion of radiography performed nor is there discussion of any prenosological evaluation.
Altered brain circulation is one of the immediate sequelae of head trauma, therefore improving circulation with aerobic exercise is an eventual treatment strategy. The study does not indicate any evaluation for circulatory disturbance of the brain, nor any circulatory functional parameters such as arterial elasticity.
There is also no discussion of the sequential steps for Return To Participation guidelines as recommended from CDC and Berlin Congress of Sports Concussion Assessment.
Recall that there are six stages of return to participation. The first to be initiated when the patient is symptom free for 24 hours before initiating any physical activity that elevates heart rate above the resting heart rate level. Most ER departments and clinicians in general are not cognicant of the gradual and systematic increase in physical exertion as part of the therapeutic recovery from a concussion.
There are no Return To Learn cognitive guidelines evaluated in this study either.
Relying on the evaluation of reduction in clinical symptomatology as the determination of recovery from head trauma is simplistic, inappropriate and may lead to long term neurological deficits.
This study is encouraging about the benefits of aerobic exercise but not at the compromise of limited to no functional neurological assessment.
