this book, "gait analysis: normal and pathological function," edited by jacquelin perry and judith m. burnfield, is a comprehensive resource on gait physiology and biomechanics. published by slack incorporated in 2010, it is a hardcover book with 551 pages and an isbn of 978-1556427664. the book is designed for orthopaedic, physical therapy, and rehabilitation professionals involved in musculoskeletal patient care, as well as for designing athletic training, physical therapy, and gait workshops. the second edition aims to provide updated data, current research, more advanced methods, and the latest equipment in gait analysis. the text is divided into six sections: fundamentals, normal gait, pathological gait, clinical considerations, advanced locomotor function, and quantified gait analysis. the first section covers the gait cycle, phases of gait, and basic functions. the second section discusses normal gait in various body parts, including the ankle-foot complex, knee, hip, head, trunk, pelvis, arm, and total limb function. the third section explores pathological gait mechanisms and deviations in different body parts. the fourth section includes clinical examples and pediatric gait analysis. the fifth section covers advanced locomotor functions such as stair negotiation and running. the sixth section presents quantified gait analysis methods, including gait analysis systems, motion analysis, muscle control, kinetics of gait, stride analysis, and energy expenditure. the book is an informative and essential resource for anyone studying or working with physio-pathological lower limb biomechanics.this book, "gait analysis: normal and pathological function," edited by jacquelin perry and judith m. burnfield, is a comprehensive resource on gait physiology and biomechanics. published by slack incorporated in 2010, it is a hardcover book with 551 pages and an isbn of 978-1556427664. the book is designed for orthopaedic, physical therapy, and rehabilitation professionals involved in musculoskeletal patient care, as well as for designing athletic training, physical therapy, and gait workshops. the second edition aims to provide updated data, current research, more advanced methods, and the latest equipment in gait analysis. the text is divided into six sections: fundamentals, normal gait, pathological gait, clinical considerations, advanced locomotor function, and quantified gait analysis. the first section covers the gait cycle, phases of gait, and basic functions. the second section discusses normal gait in various body parts, including the ankle-foot complex, knee, hip, head, trunk, pelvis, arm, and total limb function. the third section explores pathological gait mechanisms and deviations in different body parts. the fourth section includes clinical examples and pediatric gait analysis. the fifth section covers advanced locomotor functions such as stair negotiation and running. the sixth section presents quantified gait analysis methods, including gait analysis systems, motion analysis, muscle control, kinetics of gait, stride analysis, and energy expenditure. the book is an informative and essential resource for anyone studying or working with physio-pathological lower limb biomechanics.
