生物力学

The experiment used methods of sport biomechanics to investigate the electromyographic magnitude of eccentric and concentric phases under two different stretch amplitudes of drop jumps in order to understand neuromusculor characteristics of different stretch amplitudes of SSC movement.

本研究是利用运动生物力学的方法，探讨肌肉牵张缩短循环（stretch-shortening-cycle SSC）的典型动作drop jump 20、40和60cm之肌肉工作特徵，以便了解浅蹲和深蹲法的DJ跳法之离心和向心收缩二阶段的肌电活动特徵。

From traditionary nucleus pulposus exsection to spinal fusion,endoscope and minimally invasive techniques,and prosthetic disc nucleus and artificial disc replacement in recent years, however,they relieved clinical complaint temporary by means of the destruction of structure and function of lumbar intervertebral disc.

从传统的髓核摘除术到脊柱融合术、内窥镜和微创技术及近年开展的人工髓核和椎间盘置换术，但它们都是以破坏椎间盘结构和牺牲生物力学功能为代价的，不能阻止和逆转椎间盘退变，因此椎间盘退变的基因治疗和组织工程成为研究的热门课题。
