關於長時間踝關節肌肉伸張的治療方式,過去學者均以站立的方式利用病患自己的體重做為伸張力量的來源,少數則以支架(Brace,AFO)的方式對踝關節施以預力(Preload)來做肌肉伸張,這些治療方式雖抑制了部分的痙攣現象,然因無考慮不同痙攣程度的影響,究竟該施予多少伸張力量並無一標準,而導致在治療效果上也不盡相同。當病患在接受PMS治療時,踝關節承受多大的力矩及此力矩與病患痙攣程度之間的關係為何是臨床治療極需澄清的一個問題,若此問題能夠釐清,則對於不同痙攣程度治療所需的力量運用將能更為精確。本研究我們在踝關節伸張量化治療方面作深入的研究與牽張機構的設計。 In regards to the treatment of ankle spasticity with prolonged muscle stretch (PMS), past studies have suggested the use of stretch force exerted from the patient's body weight in an upright standing position. An alternative treatment is to stretch the muscle with preload force by using the brace. Although these treatment methods have partially reduced the spasticity, they have failed to provide a proper treatment criteria due to the incapacity to detect the severity of spasticity and quantify the stretch force used during PMS. This situation has caused a great variance on the treatment result. The purpose of this study is to develop a quantitative measurement system to assess the effectiveness for PMS treatment of spasticity. By further analysis with pre-post treatment effect and correlation between biomechanical and neurophysiological variables, the treatment mechanisms of PMS for spasticity will be able to understand.
