Jacquelin Perry, MD’s interest in gait began in college (UCLA). A major in physical education (1935-1940) introduced her to anatomy and provided a strong background in kinesiology with application to sports. Part of this experience was her attendance at the Physical Therapy Clinic of the Los Angeles Children’s Hospital where she began her exposure to disability. Subsequently, she became a physical therapist (Walter Reed Army Hospital, 1941), which expanded her knowledge of anatomy, kinesiology, and disability. Her physical therapy experience in Army hospitals during World War II provided a broad clinical experience (1941-1945). After the war ended, she used her GI bill to go to medical school (UC San Francisco, 1946-1950) for the specific purpose of becoming an orthopaedic surgeon. Dr. Perry’s residency in orthopaedic surgery (UCSF, 1951-1955) occurred during the period when poliomyelitis and reconstructive surgery were strong clinical programs. Observational gait analysis and experience in correcting disabled gait became daily practice. Her next move was to join the staff of the Rancho Los Amigos National Rehabilitation Center. In 1955, poliomyelitis was the entire focus of the rehabilitation program. Disability of lower limbs, spine, and arms were all major concerns while bracing and reconstructive surgery received equal emphasis. Developed in conjunction with a group of knowledgeable and dedicated physical therapists, the Rancho Los Amigos Observational Gait Analysis System became highly organized. For the first time, there was a means of cataloging the multiple dysfunctions that occur with the various types of pathology. For the past 25 plus years, they have taught this program nationwide. The organizational background of this book is based on this program.A second development was the gait laboratory (1968).During her career, Dr. Perry has received numerous awards for her pioneering work in many areas of gait and orthopaedics. She received the Kappa Delta Award (Orthopedic Research Society, 1976) for landmark work with dynamic electromyography to define muscle function in cerebral palsy and the Isabelle and Leonard H. Goldson Award in Technology (United Cerebral Palsy Research and Education Foundation, 1981). She was a Shands Lecturer (American Orthopaedic Association, 1988) and received the Shands Award (Orthopaedic Research Society, 1999). Dr. Perry received Lifetime Achievement Awards from the Gait and Clinical Movement Analysis Society (2000) and The Scoliosis Research Society (2008). In December of 2008, the University of Southern California dedicated the Jacquelin Perry Musculoskeletal Biomechanics Laboratory in her honor. Dr. Perry continues her lifelong dedication to the research and clinical application of gait. This publication encompasses the extensive work of Dr. Perry and her successful years as a therapist and a surgeon renowned for her expertise in human gait.
Judith M. Burnfield, PhD, PT is a most welcome co-author. She has excellent analytical skills and has an outstanding command of words. In addition, her scientific preparation and professional experience give her a unique perspective of impaired gait. Dr. Burnfield’s interest in gait began during a clinical internship in 1986 on the Arthritis Service at Rancho Los Amigos National Rehabilitation Center (Rancho). The analytic process encouraged during weekly gait sessions (many led by Dr. Perry) tapped into her investigative nature. Following graduation from the Physical Therapy Program at the State University of New York at Buffalo (1986), Dr. Burnfield accepted a position at Rancho Los Amigos National Rehabilitation Center. Subsequent work on the Stroke Service, Gerontology Service, and in the Polio Clinic at Rancho expanded her knowledge related to the profound impact of weakness on movement disorders. In 1996, Dr. Burnfield left her position as Director of Physical Therapy at Rancho to commence graduate studies in Biokinesiology at the University of Southern California (USC). Her doctoral research, under the advisement of Dr. Christopher Powers, focused on human and environmental factors contributing to slips and falls during walking. She co-developed and taught the introductory and then advanced observational gait analysis courses for students enrolled in the clinical doctorate of physical therapy program at USC. At the time of her enrollment in USC’s Biokinesiology program, she also pursued a position as a research physical therapist working in the Pathokinesiology Laboratory at Rancho due to her desire to enhance her clinical research skills related to normal and pathologic gait. Her work in the latter environment focused on clinical and research studies quantifying gait abnormalities through the analysis of kinematic (motion), kinetic (moment) and electromyographic (muscle activity) data. The unique research and teaching experiences in the two environments complimented each other well and provided a framework for her role instructing Biomechanics and subsequently Kinesiology in the Physical Therapy Program at Mount St. Mary’s College in Los Angeles.Following completion of her doctoral studies, Dr. Burnfield engaged in a postdoctoral fellowship with Dr. Jacquelin Perry. This mentorship had a profound influence on Dr. Burnfield’s professional development for which she is most grateful. This focused period of inquiry provided a strong foundation for their subsequent collaboration on the second edition of this book.In October 2004, Dr. Burnfield joined Madonna Rehabilitation Hospital in Lincoln, Nebraska. She serves as Director of the Institute for Rehabilitation Science and Engineering, Director of the Movement and Neurosciences Center and the Clifton Chair in Physical Therapy and Movement Sciences. Research efforts focus on developing and studying new treatments and technologies to help individuals with physical disabilities walk, exercise, and live more independently. The fully instrumented Chapin Gait and Motion Laboratory within the Movement and Neurosciences Center includes state-of-the art technology and software for conducting biomechanical and physiological analyses of movement function including a twelve-camera infrared motion analysis system, 16-channel and 10-channel portable electromyography technology, four force platforms, a footswitch system and plantar pressure mapping technology, and a 30-meter walkway with an overhead safety support track and full-body harness system. Dr. Burnfield holds adjunct faculty appointments at Creighton University, University of Nebraska– Lincoln, University of Nebraska Medical Center, and the University of Southern California. In addition to a vigorous research agenda, Dr. Burnfield continues to teach gait in the academic setting and presents both nationally and internationally on gait and rehabilitation related topics.
