This book is a practical guide to instrumented clinical gait analysis covering all aspects of routine service provision. It reinforces what is coming to be regarded as the conventional approach to clinical gait analysis. Data capture, processing and biomechanical interpretation are all described with an emphasis on ensuring high quality results. There are also chapters on how to set up and maintain clinical gait analysis services and laboratories. The book aims to describe the theoretical basis of gait analysis in conceptual terms. It then builds on this to give practical advice on how to perform the full spectrum of tasks that comprise contemporary clinical gait analysis.
-Professionals from either a clinical or technical background working within clinical gait analysis services.
-The extensive sections on data capture and processing will also be invaluable for those using gait analysis for research purposes.
-Clinicians receiving gait analysis reports and particularly those who base clinical decisions upon gait analysis results (e.g. orthopaedic surgeons) will find it useful in understanding where the data comes from and how it can be interpreted.

'This is an excellent book. Orthopedic surgeons as a whole, at least in the U.S., do not pay enough attention to gait/gait analysis. This book is a game changer. It is relevant to most lower extremity maladies. It is an essential addition to the academic orthopedic library.'
Samuel Chmell, MD, University of Illinois at Chicago College of Medicine
'Anybody who already works in a gait laboratory, would like to work in a gait laboratory, or needs to understand the processes, strengths, and weaknesses of clinical gait analysis will want easy access to this book.'
Jon R Davids, Developmental Medicine & Child Neurology, 2013
'This is a well written and illustrated text, with key references provided in each chapter. The book is approachable for all health care professionals working in the field of clinical gait analysis, whether they are new to the field or established practitioners, and is one that should be present in any gait laboratory – academic, clinical or industrial.'
David Ewins, Queen Mary’s Hospital, London
'Measuring Walking: A Handbook of Clinical Gait Analysis is written by an international expert in clinical gait analysis and provides a balanced blend of pragmatic clinical gait analysis guidance with the necessary technical detail to support high quality measures and interpretation needed in clinical gait analyses.'
Carole A. Tucker, Temple University Philadelphia
‘This book stands out in the way in which it condenses so much information into one book and makes it extremely accessible to the reader. Richard Baker has long been considered a pioneer to those involved in the gait analysis lab community, and this book will no doubt widen his audience to those people indirectly involved with analysing how people walk. Along with his co-authors, he is able to take potentially complicated subjects and break them down into manageable chunks; this makes for a very accessible read.’
Roisin Delaney, British Journal of Occupational Therapy, 2014
‘This comprehensive guide is a handbook for clinicians, students and researchers who are working in an instrumented (3-dimensional) gait laboratory. Professor Baker is internationally recognised in clinical gait analysis and this book is a compilation of his experience and knowledge, as well as the evidence-base available to inspire good practice in the gait analysis community.’
