中文摘要 | 膝關節的構造及相關功能是骨科醫生以及運動科學學者相當關心的焦點之一。近 年越來越多研究者運用動物和人類的前十字韌帶模型解釋及探討韌帶力學模式及生理機轉, 主要的原因是(一)重大的前十字韌帶傷害的病歷逐漸的增加,(二)有關於膝關節功能的 長期傷害、治療、復建間的問題。膝關節是人體中最大,最複雜的關節之一,對於休養與運 動有關的傷害是相當重要的。 前十字韌帶緊張程度及受力能力,在身體活動中是相當須要注意的。 Kain 等人 (1987) 認 為, 依序激活四頭肌與腿後肌腱群會影響最後的前十字韌帶的緊張程度, Butler 等人 (1980) 認為前十字韌帶是阻止脛骨與股骨向前運動的主要韌帶,且提供 80% 其所需的阻力 ,並可以阻止一些旋轉的運動形式,和避免關節內向側開展。Solomonow 等人 (1987) 以貓 的模型論證前十字韌帶 - 腿後肌腱群的反射弧,提供膝關節向前穩定的需求和訊號。 其機 轉有感覺神經假說加以闡明。感覺神經假說中所探討位於韌帶上的關鍵物質是「機械性刺激 接受器」 目前在人體膝關節的韌帶與關節囊中,有四種已被認同的機械性刺激接受器: ● Ruffini 氏終器 ● Pacinian 氏小體 ●類高爾基肌腱器的機械性刺激接受器 ●游離神經末梢 這四種不同型態的機械性刺激接受器,分別接受不同的刺激反應,提供中樞神經系統種種的 訊息。而這些訊息可以藉由關節反射現象的運動或動力形式,而被偵查出來。 |
英文摘要 | The issue regarding the mechanism of knee joints and its related functions is what most expert in the fields of the skeleton and the motion study concern about. Recently, more and more scholars devote their efforts to study the model of animal and human anterior cruciate ligament (ACL), trying to explain and research the kinetic mechanics and physical functions because of two main reasons: Ⅰ. The case of severe ACL damages are increasing. Ⅱ. This research on the chronic damage of knee joints will be helpful for future medical treatment and convalescence. since knee joints are the biggest and the most complicated joints in human body, doing research on it can help us understand how to maintain our health and avoid sports damages. The strain and limitation of ACL should not be neglected in body movement. Kain et al.(1987) claimed that sequence of quadriceps-hamstrings activation would affect the strain of ACL. Butler (1980) declared that ACL is the main ligament preventing the tibia and femur from moving forward with 80% resistance; moreover, it prevents some revolving movement and prohibits joints from inward developing. According to Solomonow, cat model can be applied to argue ACL the reflective arc of the hamstrings and its function of remaining knee joints forward. Besides, the neurosensory hypothesis is applied to clarify the functions of the ACL, which focuses on the critical part of ligamentous mechanoreceptors. So far, there are four types of mechanoreceptors existing on ligaments and joint capsule of human knee joints: ● Ruffini endings ● Pacinian corpuscles ● Mechanoreceptors similar to Golgi tendon organs ● Free nerve endings These four different mechanoreceptors can receive stimuli, providing central nerve system various information. And from the reflection or the movement of the joints, we can distinguish the information. |
