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\n            \u003cdiv\u003e\n\u003cstrong\u003eNumber of Pages:\u003c\/strong\u003e 277\u003c\/div\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.56 x 9.21 x 6.14 IN\u003c\/div\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003ePublication Date:\u003c\/strong\u003e May 31, 1991\u003c\/div\u003e\n            ","brand":"BooksCloud","offers":[{"title":"Default Title","offer_id":45391586918502,"sku":"9780521412216","price":111.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0599\/7255\/0758\/files\/ckpUL2tFUERuVmNRaHVoUGRNR0ZtZz09.webp?v=1775148586","url":"https:\/\/infinitylightwa.com\/products\/the-development-of-mature-walking-hardcover","provider":"Infinity Light","version":"1.0","type":"link"}
