Research areas addressed by CASBBI members — such as chronic pain, substance misuse and addiction, and mobility impairments — have major public health and societal significance. Our goal is to develop improved interventions and outcomes for these conditions.
Chronic pain is a critical public health problem. At CASBBI, we are bridging engineering, neuroscience, and rehabilitation to understand contributors to chronic musculoskeletal pain and develop effective non-pharmaceutical interventions.
Chronic neck and low back pain syndromes are complex and poorly understood, often lacking a clear etiology. These soft tissue pain syndromes often involve interactions between the musculoskeletal, circulatory, and nervous systems at multiple levels, as well as involving psychosocial factors. The lack of adequate quantitative methods for characterizing the relevant systems involved in these complex disorders is a critical barrier to clinical diagnosis, systematic studies of the underlying mechanisms, and development of effective treatments for these widely prevalent conditions.
At CASBBI, NIH-funded research has pioneered the use of ultrasound imaging and elastography to objectively characterize muscle tissue properties and vascular remodeling in chronic neck pain, before and after dry needle perturbation. Our collaborative group also pioneered the use of microdialysis to describe the biochemical milieu of muscle in myofascial pain. The long-term goal of our research program is to understand the pathogenesis and pathophysiology of myofascial pain, and develop effective therapeutic interventions. Our highly interdisciplinary research team combines expertise in imaging, rehabilitation, physiatry, neuroscience, biomechanics, and proteomics.

Addictive behaviors (including substance use problems, disordered eating behaviors, and other compulsive behaviors) have significant negative consequences for the individual and society. At CASBBI, we are bridging psychology, neuroscience, social science, and engineering to understand addictive behaviors, develop clinical interventions, and empower communities of recovery using technology.
Like many health problems, addictive behaviors are rooted in dysfunction in biopsychosocial systems. Addiction is a complex and dynamic phenomenon with causes operating at multiple spatial and temporal scales, and cycles of wellness and relapse. Understanding the interconnections among addictive behaviors, social/environmental factors, genetics, and brain networks will provide new analytic tools for the study of the mechanisms of addiction and suggest new strategies for treatment.
At CASBBI, our NIH-funded program of research is investigating the role of emotion- and reward-related brain function in the development and prevention of substance use in adolescence, using fMRI and ecological momentary assessment (EMA). Another collaborative project is investigating the use of technology to empower communities of recovery around individuals with substance use disorders to achieve measurable improvements in long-term health and wellness.

Nearly 1 in 5 Americans currently live with a physical disability that affects their activities of daily living. At CASBBI, we are bridging neuroscience, engineering, and rehabilitation to understand and improve function in individuals living with mobility impairments.
Human movement is dependent on perception-action interactions. These interactions are constantly updated in response to experience, a process known as sensory-motor adaptation. Sensory-motor adaptation is critical for functioning successfully in one’s environment.
At CASBBI, we are collaborating with the MedStar National Rehabilitation Hospital and the Washington DC Veterans Affairs Medical Center to investigate mechanisms of motor recovery following stroke and amputation, and developing novel assistive technologies, including dexterous prosthetic control systems for amputees and novel lightweight exoskeleton systems for subjects with spinal cord injuries.
