Research, undertaken at one of the world's leading gait analysis centers, involved over 400 studies on a total of nearly 300 children in ten age-groups from one to seven years. Data are presented on anthropometric measurements; tests of developmental progress; time\/distance parameters such as stride length and walking velocity; twelve joint angles on each side measured throughout the gait cycle; dynamic electromyography of phasic activity in seven lower-extremity muscle groups; and force measurements including vertical force, fore\/aft shear, medial\/lateral shear and torque. At each age, composite joint-angle graphs and time\/distance parameters are brought together with film tracings of a representative child in that age group. In addition, advanced methods of statistical analysis have been applied to the joint-angle data to define prediction regions within which ninety-five percent of normal children should lie throughout the gait cycle. Finally, a \"decision tree\" is presented from which a fitted age can be inferred for a subject based on non-age-specific data gathered in a motion analysis lab. Practical applications are demonstrated in a chapter devoted to two case studies.\u003c\/p\u003e","brand":"Mia Karts","offers":[{"title":"Default Title","offer_id":52158545035552,"sku":"NEW0521412218","price":89.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/7426\/3840\/files\/61wdH9378JL.jpg?v=1786081215","url":"https:\/\/miakarts.com\/products\/the-development-of-mature-walking-clinics-in-developmental-medicine-mac-keith-press-0521412218","provider":"Miakarts Books","version":"1.0","type":"link"}
