Physical Activity Interventions in Rehabilitation Programs for Outpatients With Mild Traumatic Brain Injury.

Introduction

There is limited scientific evidence about the optimal content and parameters of physical activity (PA) interventions for rehabilitation outpatients with persisting symptoms of a mild traumatic brain injury (mTBI). Clinicians have thus had to develop services based on their expertise, feasibility and patient needs.

Objectives

This study aimed to document PA interventions delivered in specialized programs of a Canadian province offering outpatient rehabilitation services for individuals with persisting symptoms of mTBI to inform clinical intervention development and future research. Materials and methods: Cross-sectional study using an online survey containing 32 multiple choice and short open-ended questions to be answered by program administrators, with their clinical team's input. Content analysis and descriptive statistics were used.

Results

Data from 94% of rehabilitation sites (n = 17) revealed that PA interventions are delivered to children (n = 4), adults (n = 15) and older adults (n = 5) with mTBI symptoms lasting ≥1 month to ≥1 year post injury. PA interventions aim to increase participation (n = 14), improve body functions (n = 9), manage persisting mTBI symptoms (n = 5) and improve self-management skills (n = 5) and knowledge (n = 4). Interventions include individual (n = 15) or group-based (n = 12) format, home-programs (n = 7), and teaching/education (n = 6). Most PA interventions include aerobic and resistance exercises. PA dosage parameters vary greatly.

Conclusion

Clinical experts use multimodal interventions for rehabilitation program users that target improvement in body functions, participation and symptoms. The results can inform the development, enhancement and evaluation of PA interventions. Studies evaluating the effectiveness of these interventions for this clientele are warranted.
