项目摘要

Main results are summarized as follows :(1) We developed a model that simulates gaits of patients with flaccid paralyzed legs, who usually require braces such as Walk-abouts and canes.(2) Comparing pathological gaits of patients with muscular dystrophy and after pelvic osteotomy, the pelvic motions of them in the frontal plane were just the opposite. It results from the difference of the incomplete or complete loss of function of the abductor muscle at their hip joints.(3) We developed an estimating method of inner forces during exercise. This method is based on exercise models and measurements of the integrated EMG and external forces during exercises. In spite of this simple method, the estimated results were very similar to the results by in vivo measurements abroad.(4) In the electrical stimulation method using surface electrodes, it is important to study how the electrode can stimulate skeletal muscles deeply. We ensured how by using the intensity of the MR imaging reflecting muscle activities. Also we tern developed a new electrical stimulation method.(5) Advantages of the new method were confirmed in a long-term experiment on upper and lower limbs in comparison with other training methods.(6) Strain distribution of entire ligament could be measured three-dimensionally.(7) Reciprocal gait orthosis was applied to improve characteristics of hemi-paralytic walking. The circumduction gait and the rotational movement of upper torso were improved.(8) The finite element method was performed using 3-dimensional models to examine the biomechanical characteristics of the femoral component in resurfacing hip arthroplasty. The highest stress concentration was observed in the same region of the neck of a patient with a nontraumatic femoral neck fracture.

主要结果总结如下：（1）我们开发了一个模型，该模型模拟了瘫痪腿的患者的步态，他们通常需要诸如步入式和拐杖等牙套。（2）比较肌肉营养不良的患者的病理步态和骨盆骨手术后的肌肉运动障碍，其骨盆骨骼的正面是对立的。它是由于髋关节在臀部关节处的不完全或完全丧失功能的差异而导致的。（3）我们在运动过程中开发了一种内部力的估计方法。该方法基于运动模型和锻炼过程中综合EMG和外部力量的测量。尽管有这种简单的方法，但估计的结果与在国外的体内测量结果非常相似。（4）在使用表面电极的电刺激方法中，重要的是研究电极如何深入刺激骨骼肌。我们通过使用反映肌肉活动的MR成像的强度来确保如何使用。（5）与其他训练方法相比，在长期和下肢的长期实验中证实了新方法的优势。（6）可以三维测量整个韧带的应变分布。（7）相互步态的正直形成可改善半步行的特征。（8）使用3维模型进行了有限元方法，以检查股骨成分的生物力学特征，以改善上躯干的圆周步态和上躯干的旋转运动。在患有非创伤性股骨颈部骨折的患者颈部的同一区域中观察到最高的应力浓度。
