Historical highlights The XIX th Century: the gait century Chronophotography Historical highlights The XIX th Century: the gait century Muybridge (1830-1904) Historical highlights The XIX th Century: the gait century Historical highlights The XIX th Century: the gait century Animal Locomotion Animals in Locomotion The Human Figure in Motion Muybridge (1830-1904) Wilhelm Braune & Otto Fischer (1891) – Conducted the first 3D analysis of human gate, making precise mathematical analysis possible. They used night photographs of light tubes over a black suit. They used night photographs of light tubes over a black suit. The preparation of each subject took 8h. The CG and moments of inertia of the body and all segments were calculated experimentally, with the use of two frozen cadavers Braune died after data collection and Fischer took several years to complete data processing, which is now performed in REAL TIME Der Gang des Menschen (1895-1904)
Historical highlights The XIX th Century: the gait century Du Bois Reymond (1818-1922) and Duchene (1806-1875) – Laid the foundations of electromyography Refined the methods for measuring currents in 1841, and traced electricity in contracting muscle to its independent fibres Volkmann (1862) – Described the effects of pressure on bone growth In 1866 published Physiologie des Movements, which describe the function of every important superficial muscle Van Mayer (1867) – Described the relationship between the bone architecture and its function Historical highlights The XX th Century Characteristics of the XXth century that influenced the development of <strong>Biomechanics</strong>: Mechanical, industrial and technological development associated to two world wars Popular, social and financial recognition of Sport and human performance Explosion of financial support for medical and health care research Cochran & Stobbs (1968), from Bartlett (1997) Silveira et al. (2005), Radiol. Bras. Historical highlights The XIX th Century: the gait century - Measuring methods were developed to quantify kinematics and kinetics, and were extensively applied to human gait analysis - Measuring methods were developed to quantify electrical current during muscular activity - Engineering principles were applied to biological and biomechanical analysis Historical highlights The XIX th Century: the gait century Light-trace Photography Vilas-Boas (1994)
