{"product_id":"the-development-of-mature-walking-david-sutherland-9780521412216","title":"Development of mature walking","description":"This important monograph summarizes a comprehensive study on the maturation of walking in normal children. 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 Olsen, Edmund Biden\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 0521412218\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9780521412216\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Mac Keith Press\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 12\/14\/2011\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 277\u003cbr\u003e\u003cb\u003eFormat:\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","brand":"David Sutherland","offers":[{"title":"Hardcover","offer_id":43920014704895,"sku":"9780521412216","price":70.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/products\/img_b58988eb-7dc7-4f1b-9d35-0dbbffd3e477.jpg?v=1680813119","url":"https:\/\/www.whiterainbookhouse.com\/products\/the-development-of-mature-walking-david-sutherland-9780521412216","provider":"WR Book House","version":"1.0","type":"link"}
