Official title
Randomized Controlled Trial of Combined Cognitive Rehabilitation and Exercise Training for Learning and Memory in Persons With Moderate to Severe Traumatic Brain Injury
Overview
New learning and memory impairment (NLMI) is a common and devastating manifestation of TBI associated with substantial life burdens. Persons with moderate to severe TBI have shown improvement in NLM for prose material (e.g. story) as well as beneficial changes in default-mode network (DMN) activation during list-learning19 following treatment with the Kessler Foundation modified Story Memory Technique® (KF-mSMT®). Benefits, however, were moderate and did not yield downstream improvements in daily life. It is thus critical to examine other approaches to complement the KF-mSMT® for robustly managing NLMI in TBI. The proposed RCT will be the first to include aerobic exercise training (AET) as a highly-promising complement to the KF-mSMT® for robustly managing NLMI, examining impact on NLM, its neural correlates, and daily life in NLM impaired persons with moderate-to-severe TBI. We thus propose a two-arm, parallel group, double-blind RCT comparing the effects of the KF-mSMT+AET with the KF-mSMT+S/T (active control condition) on NLM (Aim 1), hippocampal MRI (Aim 2), and daily life outcomes (Aim 3). 60 NLM impaired persons with moderate-to-severe TBI will be randomized to one of 2 conditions (30 per condition). Each condition will take place 3 days per week for 12 weeks and will be supervised by KF personnel. Participants will be blinded as to the intent of the conditions. We will further explore baseline predictors of clinically meaningful changes in NLM for those completing the KF-mSMT + AET condition (Exploratory Aim 4). If successful, this trial will position combinatory KF-mSMT and AET within the clinician's arsenal for robustly managing NLMI in persons with TBI. By augmenting the effects of KF-mSMT with AET, this treatment aims to exert a powerful countermeasure to TBI-related NLMI, and ultimately help those with TBI-related NLMI return to the workforce, independently manage their everyday lives, and maintain optimal quality of life. Additionally, while rigorously designed to answer the scientific question of the relative benefit of AET with the KF-mSMT, the proposed study is will likely provide some level of benefit to all study participants. If successful, this trial will provide Class I evidence of combined KF-mSMT and AET for rehabilitating NLMI in TBI, based on standards published for therapeutic trials by the American Academy of Neurology, thus positioning such an approach within the clinician's arsenal for robustly managing NLMI. By augmenting the effects of KF-mSMT with AET, we anticipate this treatment will ultimately help those with TBI-related NLMI return to the workforce, independently manage their everyday lives, and maintain optimal quality of life.
