英文摘要 | To assess gait patterns in Children is the research topic of biomechanist, orthopedic surgeons, pediatric physician, and physical therapists. The quantitative gait analysis (temporal-spatial parameters, joint angles, joint moments and joint powers etc.) is becoming tool for evaluating the outcome of pathological gait, especially for CP children. The major goal of this study is to establish normative data of children and to find differences in gait patterns between children and young adults. A kinematic analysis system and two forceplates were used to measure the normal gait patterns of 27 healthy children aged from four to six years and 7 young adults (male, 22-27 years old) were evaluated in this study 23 reflective markers were attached to each subject on specific anatomical positions and all subjects were asked to walk at their self-selected speed on a 10.7m long, 2.05m wide walkway. At least 10 trials were collected for each subject. Significant differences were found between children and adults by the analysis of temporal-spatial parameters, joint angles, joint moments and powers. No signify cant differences were observed among children subgroups. Comparing with results of Beck (1981), Sutherland (1988) and Gage (1991), no significant differences were found. Children have short stride time and double support duration, larger range of hip flexion/extension and abduction/adduction angles. There is a tendency that the stride time increase by increasing age. In the analysis of foot-floor reaction forces, adults have larger vertical force than children. Adults utilized more net extensor moment at ankle than children during the preswing phase and make use of a greater knee flexor moment at knee during terminal stance phase. In addition, adults utilize greater ankle eccentric and concentric powers at midstance and terminal phase than children. By analyzing these variables, quantitative description of walking patterns for children (4-6 years) and adults (22-27 years old) in Taiwan were obtained. Data presented in this study can be a reference for describing and comparing children pathological walking patterns. |
