In 2016, funded by a $16 million grant from Scythian, the multidisciplinary Miller School team embarked on a five-year study to examine the effects of combining CBD (a cannabinoid derivative of hemp) with an NMDA antagonist (an anesthetic used in animals and humans) for the treatment of traumatic brain injury and concussion. The researchers believed the combination could reduce post-injury brain cell inflammation, headache, pain and other symptoms associated with concussion.
The findings of a pre-clinical pilot study were recently released, and they show that the combination therapy improved the cognitive functions of animals, compared with those treated with a single vehicle. In addition, there were no adverse effects from either the combination therapy or the individual components.
“There needs to be more systematic research in this field in order to study the neuroprotective properties of CBD, and to improve treatment for those sustaining mild-to-moderate TBI (traumatic brain injury) and concussion,” said Gillian A. Hotz, Ph.D., professor of neurological surgery, and director of the KiDZ Neuroscience Center at The Miami Project and the University of Miami Sports Medicine Institute concussion program.
Most doctors who treat young athletes for concussion know that the injury increases the risk of having a car accident, but barely half counsel their patients against driving, a U.S. study suggests.
Researchers invited members of the American Medical Society for Sports Medicine to complete a 24-question online survey about their attitudes toward driving after a concussion and what they tell their patients. The study team examined answers from 333 doctors who had managed at least 12 concussions per year.
“In our study, 83 percent of physicians felt that concussion put individuals at a greater risk of a motor vehicle crash yet fewer than half, 49 percent, routinely counsel their patients about driving,” said lead author Dr. John Lucas IV of the Sports Medicine Institute at the Spartanburg Regional Healthcare System in South Carolina.
Concussion has been released—and with it, a wave of opinions on whether the film about chronic traumatic encephalopathy (CTE) among National Football League (NFL) players will make a difference in how the league, and society at large, view sports that involve high-impact body contact.
The movie, which opened on December 25, stars Will Smith as forensic pathologist Bennett Omalu and chronicles Omalu’s battle with the NFL to bring attention to CTE and its relationship to repeated head injury.
And while there were plenty of reviews of the movie itself, even more media attention was focused on what the film had to say about the NFL, the sport of football, America’s passion for the game, and the chances that a big-budget movie would spark any meaningful change that would reduce injury. Here’s a quick rundown of some of the reactions published recently.
The transformative power of physical therapy to treat diverse conditions is at the heart of recent Move Forward Radio episodes.

Pregnant and postpartum exercise
During pregnancy and childbirth a woman’s body goes through profound changes in a relatively brief period of time. For women who exercise during or after pregnancy, failure to respect those changes has the potential to lead to problems. Christy Martin, PT, DPT, SCS, who specializes in sports physical therapy, and Vicki Lukert, PT, PRPC, who specializes in pelvic health, outline how pregnant and postpartum women can exercise safely and how to spot warning signs for problems that might require medical attention.
