    3-D Analysis of Human Movement

  • Human Movement Science - Guest editorial
    • Michael W. Whittle, Jean-Pierre Blanchi
    The International Society of Biomechanics Technical Group on the Three-Dimensional Analysis of Human Movement held its inaugural meeting in the delightful city of Grenoble, in the French Alps, in July 1996. The papers in this special issue are based on presentations made at that meeting and at the associated Summer School.

  • A gait analysis data collection and reduction technique
    • Roy B. Davis, III, Sylvia Õunpuu, Dennis Tyburski and James R. Gage
    The clinical objective of the gait analysis laboratory, developed by United Technologies Corporation (Hartford, CT, USA) in 1980, at the Newington Children's Hospital is to provide quantified assessments of human locomotion which assist in the orthopaedic management of various pediatric gait pathologies. The motion measurement system utilizes a video-based data collection strategy similar to commercially available systems for motion data collection. Anatomically aligned, passive, retroreflective markers placed on the subject are illuminated, detected, and stored in dedicated camera hardware while data are acquired from force platforms and EMG transducers. Three-dimensional marker position information is used to determine: (i) the orientation of segmentally-embedded coordinate systems, (ii) instantaneous joint center locations, and (iii) joint angles. Joint kinetics, i.e., moments and powers, may also be computed if valid force plate data are collected.

  • How closely do surgeons follow gait analysis recommendations and why?
    • Tishya A.L. Wren, Kevin Woolf and Robert M. Kay
    Gait laboratory recommendations for surgery were compared with actual surgeries performed in 30 consecutive patients.The agreement between the procedures performed and those recommended by the gait laboratory averaged 93.2 ± 13.4% overall and 86.0± 18.3% excluding patients referred by the gait laboratory physician. For 23 patients (77%), the recommended surgeries exactly matched the surgeries ultimately performed. In the other patients, seven procedures that had not been recommended were performed, and seven procedures that had been recommended were not performed. Explanations for the differences included preoperative clinical or radiographic evaluation, intraoperative assessment, changes in function between gait analysis and surgery, and patient/family request.

  • Measurement of Lower Extremity Kinematics During Level Walking - (open access)
    • M. P. Kadaba, H. K. Ramakrishnan, and M. E. Wootten
    A simple external marker system and algorithms for computing lower extremity joint angle motion during level walking were developed and implemented on a computer-aided video motion analysis system (VICON). The concept of embedded axes and Euler rotation angles was used to define the three-dimensional joint angle motion based on a set of body surface markers. Gait analysis was peformed on 40 normal young adults three times on three different test days at least 1 week apart using the marker system. Angular motion of the hip, knee, and ankle joints and of the pelvis were obtained throughout a gait cycle utilizing the three-dimensional trajectories of markers. The effect of uncertainties in defining the embedded axis on joint angles was demonstrated using sensitivity analysis.

    Position and orientation in space of bones during movement: anatomical frame definition and determination
    This paper deals with methodological problems related to the reconstruction of the,position and orientation of the human pelvis and the lower limb bones in space during the execution of locomotion and physical exercises using a stereophotogrammetric system. The intention is to produce a means of quantitative description of joint kinematics and dynamics for both research and application.

    Position and orientation in space of bones during movement: experimental artefacts
    This paper deals with the experimental problems related to the reconstruction of the position and orientation of the lower limb bones in space during the execution of locomotion and physical exercises. The inaccuracies associated with the relative movement between markers and underlying bone are analysed.

  • Principal component models of knee kinematics and kinetics: Normal vs. pathological gait patterns
    • Kevin J.Deluzio, Urs P. Wyss, Benny Zee, Patrick A. Costigan, CharlesSerbie
    "Gait data were collected on a group of 29 asymptomatic elderly subjects to describe knee joint kinematics and kinetics as measured by the three components of the bone-on-bone forces, net reaction moments and relative knee angles. Each of these gait measures were considered separately in the development of Principal Component Models (PCMs) to describe the variation of the normal subjects throughout the gait cycle. The statistical similarity of patients' gait curves (waveforms) to the pattern of normal subjects' gait waveforms was assessed using the PCMs. The PCMs consider data from the entire gait cycle and detect statistically significant waveform shapes using measures of distance from normal."

    "To determine the normal gait patterns in childhood, gait studies were performed on 186 normal children between the ages of one and seven years. Rotations of the lower-extremity joints in the sagittal, frontal, and transverse planes; step length; cadence; walking velocity; and duration of single-limb stance (as percentage of the gait cycle) were analyzed throughout a walking cycle using high-speed movies, a Graf-Pen sonic digitizer, a computer, and a plotter as well as electromyograms."

  • The evolution of clinical gait analysis part l: Kinesiological EMG
    • David H. Sutherland
    "In 1996, I was asked by Roy Davis, President of the Gait and Clinical Movement Analysis Society, to be the presidential guest speaker at the Birmingham, AL, annual society meeting and present a talk on the development of clinical gait analysis. Following my presentation, James Gage, Editor-in-Chief for Gait and Posture, and David Winter, Associate Editor for review articles requested a manuscript for publication. To address this task I have the advantage of being a participant throughout this exciting era and of personally knowing most of the people mentioned in this manuscript. To prepare for this assignment, I wrote letters and/or made phone calls to them. Their replies to my inquiries, plus their publications, provide documentation for this review paper. The opinions expressed, for better or worse, are my own. Due to space limitations, only a partial list of the many that have contributed is presented and I regret that not all of the important contributors have been included. In some instances they will be found in Part II and Part III. Hopefully, later publications on this subject will correct the omissions."

  • The development of mature gait
    • David H. Sutherland
    We must understand the natural history of immature walking in order to define and interpret pathological gait in young children. Step length, cadence and walking velocity show evidence of both central nervous system maturation and growth until approximately 4 years of age. Until 4 years-of-age the step factor (step length divided by leg length) increases, but thereafter the step factor remains constant and adult-like. After 4 years-of-age the changes in velocity, cadence, step length in normal children are appropriately attributed to changes in limb length. Dynamic joint angle measurements indicate stabilization of gait by 3 to 4 years-of-age.

    The aim of this systematic review was to evaluate and summarize the current evidence base related to the clinical efficacy of gait analysis. A literature review was conducted to identify references related to human gait analysis published between January 2000 and September 2009 plus relevant older references.
