Is High-Intensity Training Advantageous in Individuals with Chronic Traumatic Brain Injury ?
Risk for Behavioral Disorders Increased in Children after mTBI
The risk for a new affective or behavioral disorder is increased in children up to four years after sustaining mild traumatic brain injury ( mTBI ), according to a study published online in Pediatrics .
Richard L . Delmonico , Ph . D ., from Kaiser Permanente Vallejo Medical Center in California , and colleagues conducted a cohort study of mTBI cases ( 17 years of age and younger ; diagnosed from 2000 to 2014 ) and matched controls within an integrated health care system . The analyses included 18,917 cases and 37,834 controls , randomly selected and matched for age , sex , race / ethnicity , and date of medical visit .
The researchers found that across the first three years after injury ,

adjusted risks for affective disorders were significantly higher for the mTBI group , especially during the second year ( 34 % increase in risk ). At years 2 and 4 , the adjusted risks for behavioral disorders were significant , with up to a 37 % increase in risk . The risk for postinjury affective and behavioral disorders was highest among 10- to 13-yearold patients .
“ Sustaining mTBI significantly increased the risk of having a new affective or behavioral disorder up to four years after injury ,” the authors write . “ Initial and ongoing screening for affective and behavior disorders after mTBI in children and adolescents can identify persistent conditions that may pose barriers to recovery .” g
A new study suggests that high-intensity training ( HIT ), compared to conventional training , may improve walking ability in patients with chronic traumatic brain injury ( TBI ). Possible secondary benefits may include improved aerobic capacity / efficiency and cognition .
The work is published in the Journal of Neurotrauma .
T . George Hornby , PT , Ph . D ., from Indiana University School of Medicine , and co-authors , evaluated the effects of HIT focused on stepping practice versus conventional training on walking in individuals with chronic TBI . HIT focused on maximizing stepping practice while trying to achieve higher cardiovascular intensities . The investigators observed greater increases in 6-minute walk test and peak treadmill speed during exercise testing following HIT vs . conventional training .
“ The present and previous results suggest that such training interventions may be important components of rehabilitation interventions to improve walking and possibly other secondary outcomes for individuals with chronic TBI , consistent with data in patients with other acute-onset neurological injuries ,” stated the investigators .
“ This is a small but important randomized controlled trial . It provides initial evidence that higher intensity cardiovascular training can be beneficial for people living with chronic effects of traumatic brain injury . I am excited to see where this field goes in the future ,” says David L . Brody , MD , Ph . D ., Editor-in-Chief of Journal of Neurotrauma . g
