R. Tyler Richardson, Ph.D., is an Assistant Professor of Kinesiology at Penn State Harrisburg. He received his undergraduate training in Mechanical Engineering before completing his master’s and doctoral degrees in Biomechanics and Movement Science all from the University of Delaware.
Dr. Richardson’s research aims to advance the understanding of shoulder and upper extremity function and to apply that knowledge to improve individuals’ lives. The heart of his work centers on measurement of scapular (shoulder blade) motion. Knowledge of dynamic scapular orientation is challenging to acquire but is required to distinguish between scapulothoracic (scapula relative to thorax) and glenohumeral (arm relative to scapula) contributions to global shoulder motion. This joint-specific information is essential to quantifying healthy and pathological shoulder function, measuring the effect of clinical interventions, understanding injury risks, and identifying factors that optimize athletic performance.
Dr. Richardson’s clinical work investigates shoulder function and the effects of surgical intervention in children with brachial plexus birth injuries, idiopathic scoliosis, and cerebral palsy through partnerships with Philadelphia Shriners Hospital for Children, A.I. du Pont Hospital for Children, and the University of Delaware. His work in sports biomechanics examines the relationships between shoulder mechanics, risks of injury, efficacy of rehabilitation regimens, and performance in baseball pitchers. He is currently the director of the Kinesiology Biomechanics Laboratory.
