Forensic Gait Analysis

By Haydn D. Kelly Copyright 2020

    Forensic Gait Analysis examines the inter-section of podiatric medicine with forensic investigation—that which links or dissociates a suspect to a crime through analysis of their gait, that is their movement—how an individual walks, runs, and bends.

    This book provides a concise explanation of how an individual's gait and biomechanics are forensically analysed and compared, using video imagery in the process of human identification and investigations. Along with the presentation and delivery of material with case law references illustrating the use of expert evidence. 

    Gait analysis is a long-standing component of the diagnostic and therapeutic tool set of medical disciplines, although the knowledge goes back much further.

    The area has also captured the interest of technology engineers and others, as the development and use of forensic gait analysis as an investigative and evidential device continues to widen.


    • Presents succinct knowledge on forensic gait analysis.

    • 100+ illustrations with photographs and diagrams; over 850 references.

    • Considers the technical and scientific basis of the field including, the history of gait, musculoskeletal, neurology, emotions and gait, forensic statistics, photogrammetry, and recognises the trajectory of development into IT and software solutions.

    • Coverage on CCTV imagery and other video footage for use in the process of identification and investigations.

    • Details are provided on report writing and giving expert evidence in the legal systems.

    • Contributors across all subject areas.

    This definitive fully referenced text on Forensic Gait Analysis is a welcome publication for healthcare professionals, lawyers, counsel, investigators, forensic practitioners, and students wishing to know more on the subject and this growing domain.

Former Elected Dean, Faculty of Podiatric Surgery (London) and during his tenure secured access to government resources for the further development of podiatric surgery and podiatry. Haydn Kelly has published in journals, periodicals, book chapters, and given presentations at international scientific conferences, with lectures on forensic gait analysis, biomechanics of foot and lower limb injuries, foot pathology, and podiatric surgery. He has also contributed to news items with television appearances. Having treated over 100,000 patients, and a clinical career in London’s Harley Street over three decades. He continues internationally extending the uses of gait analysis and the application of innovative medical IT and processing capabilities.
