Mild traumatic brain injury (mTBI) has emerged as a significant public health issue. Increases in both the prevalence and awareness of this injury have resulted in a greater demand for mTBI-informed care. Our exploratory, qualitative study examines the work lives of front-line mTBI professionals. Findings suggest that mTBI rehabilitation work often requires substantial emotional energy given the impact that injury-related issues have on professionals' therapeutic work with clients. We suggest that social work, with a focus on the psychosocial implications of injury and recovery, is well-positioned to take a larger role in mTBI care and rehabilitation.
