A new study from the University at Buffalo, New York, shows that adolescents can accelerate recovery after a sports-related concussion and reduce the risk of prolonged recovery by doing aerobic exercise within 10 days of being injured.
Released on September 30 Lancet Child & Adolcent HealthA randomized controlled trial conducted by researchers at the UB Concussion Clinic found that the team 2019 study Was announced in JAMA Pediatrics..
New studies show for the first time that the symptom threshold is aerobic exercise— Means exercise that does not exacerbate symptoms — Starting within 10 days, participants reduced their risk of persistent symptoms after a concussion by 48%.
“This study clearly shows that rigorous physical rest until the symptoms resolve spontaneously is no longer an acceptable method for treating sports-related cerebral adolescents,” Jacobs Medical School said. John J. Lady, the first author of orthopedics at the university, said. Director of the UB Concussion Management Clinic in UB Biomedicine and Biomedicine, and UBMD Orthopedics and Sports Medicine.
Physical activity prescription
“Our findings suggest that doctors not only allow, but also prescribe subsymptomatic thresholds of physical activity immediately after a sports-related concussion to accelerate recovery and reduce the risk of delayed recovery. It shows that we need to consider it, “he said.
Adolescents are the most vulnerable age group to concussion and take the longest to recover.
The new discoveries are the result of extensive research by Leddy and colleagues Barry S. Willer, Ph.D., a professor of psychiatry at Jacobs School in UB, a research director at a concussion management clinic, and a senior author of the treatise. Leddy and Willer have spent years investigating how concussion affects them. Young athlete..
Their internationally known study played an important role in the evolution of guidelines that no longer state that athletes recovering from a concussion should be prescribed complete rest.
They began this series of studies in 2000 after co-developing guidelines for returning to play after a concussion at the International Olympics. Since this was a known problem after concussion, they were interested in developing a safe and systematic assessment of exercise tolerance.
“We are how patients Heart disease Perform the prescribed exercise by identifying a safe threshold at which the patient can exercise. We have developed the Buffalo Concussion Treadmill Test by adopting the Heart Treadmill Test to stress the brain rather than the heart. Since regular aerobic exercise has been found to be good for brain health, the goal was to use asymptomatic threshold exercise to see if it would help restore a confused brain. “
Non-pharmacological, safe and effective
“As current studies show, this approach is non-pharmacological, safe and effective,” Leddy said, adding that no adverse events have been reported.
Participants in the study were adolescents between the ages of 13 and 18 who had a concussion while playing sports. A total of 118 adolescents were included, 61 received aerobic exercise treatment and 57 received placebo treatment for stretching exercises that did not increase heart rate.
People in the aerobic exercise group took a median of 14 days to recover from a concussion, while those in the stretch exercise group took 19 days.
The current survey differs from the team’s 2019 survey in the following ways:
- Two new sites have been added. This was done for participants seen at UB-related community sports medicine clinics and two hospital-related clinics. One is the Philadelphia Children’s Hospital (connected to the University of Pennsylvania) and the Boston Children’s Hospital (connected to Harvard Medical School). We tend to see patients with more serious injuries.
- Previous studies relied on self-reporting the amount and intensity of exercise that participants received, but the current study provided all participants with a heart rate monitor to wear during exercise. rice field. This allowed the researchers to confirm that the participants actually followed the doctor’s prescription for aerobic exercise.
- This study used a different study design called “therapeutic intent” and included all participants, including those who dropped out before completing the study. This is an approach that makes it more difficult to get positive results, but it more reflects a real-world concussion. process.
Especially with the use of heart rate monitors, UB researchers have revealed clearer images of the aerobic exercise sessions that participants were conducting at home.
“We found that participants were very enthusiastic about following the prescription, and those who followed the prescription, or who may have exceeded the 20-minute exercise prescription a day, should take the prescription. It was a much faster recovery than those who didn’t obey, “Willer said. “This finding is important because delayed recovery can be quite costly to adolescents, including academic difficulties, the risk of depression, and poor quality of life.”
Leddy and Willer said there are several possible reasons why this approach may be effective. This is associated with the physiological and neurological benefits that result from aerobic exercise, such as strengthening neuroplasticity (ie, repairing neurons).
“The results of this second study provide much stronger evidence that the Buffalo protocol is not only effective, but also effective for those who provide treatment and for all adolescent athletes who experience concussion. I am very pleased to do that, “Willer said. “Importantly, the benefits of prescribed aerobic exercise were equally experienced by both genders.”
The UB study focused only on adolescents recovering from sports-related concussion. Other surveys Concussion In non-sports environments, such an approach may be effective, but it has been found to not work as quickly or effectively as athletes do. In adults, aerobic exercise approaches work, but according to Leddy, they usually need to be combined with other treatments.
“In contrast, this kind of side symptom Aerobics Approaches are often the only treatment needed by adolescent athletes. “
