    Dr. Finley is the director of the Locomotor Control Laboratory within the Division of Biokinesiology and Physical Therapy. The primary objective of Dr. Finley's research is to better understand how locomotion is controlled and adapted in both the healthy and injured neuromuscular system. The lab develops theoretical models and experiments based on principles of neuroscience, biomechanics, and exercise physiology to identify the factors that guide learning and rehabilitation. Ultimately, the goal of Dr. Finley's work is to design novel and effective interventions to improve locomotor control in individuals with injury to the nervous system.

    Altmetrics Details PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication.
