{"product_id":"the-development-of-mature-walking-9780521412216","title":"The Development of Mature Walking","description":"This important monograph summarizes a comprehensive study on the maturation of walking in normal children. 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.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e David Sutherland, Richard Olshen, Edmund Biden\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Mac Keith Press\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 05\/31\/1991\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 277\u003cbr\u003e\u003cb\u003eBinding Type:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.13lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.21h x 6.14w x 0.56d\u003cbr\u003e\u003cb\u003eISBN:\u003c\/b\u003e 9780521412216\u003cp\u003e\u003ci\u003eThis title is not returnable\u003c\/i\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Mac Keith Press","offers":[{"title":"Hardcover","offer_id":40029438050419,"sku":"9.78E+12","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/9255\/0515\/products\/img_19885923-2f51-42b7-929a-287ecacf2d66.jpg?v=1650752372","url":"https:\/\/bookstorenmore.com\/products\/the-development-of-mature-walking-9780521412216","provider":"Bookstore N More","version":"1.0","type":"link"}
