中風病人肌肉痙攣量化的方法之一是生物力學評估,由先前之研究發現在
牽張過程中,被牽張肢體慣性力矩會影響反射力矩之量測,並對痙攣量化
評估造成不利,因而本研究目的在於建立肌肉痙攣數學模型,並判認出系
統的參數,以了解肌肉痙攣的機轉,並由人體實驗來驗證,吾人所建立的
模型之可靠性。本研究建立了三種模型分別為:線性模型及兩個非線性模
型,而非線性模型的主要差別,在於受測者是以躺姿,所以必須考慮重力
的因素,而相同的是將肘屈肌牽張反射模擬成一個非線性彈簧。由解剖生
理我們了解,當中風病人有肌肉痙攣產生時,是由兩部份的牽張反射所產
生的,一為與速度有關之反射,另一為與位置有關之反射,藉由本研究發
展之肌肉痙攣模型,可以清楚的分解出這兩部份。將有助於對肌肉痙攣機
轉的了解。由實驗結果顯示藉由肌肉痙攣模型,我們可以判認出與速度無
關之反射力矩,而扭剛性係數可以量化肌肉痙攣程度。在臨床上將有助於
中風病人之診斷、評估及復健。

The biomechanical assessment is one of the methods of quant-
ify themuscle spasticity in stroke patients. From previous
stu- dies, we know that during the stretch process, inertial
torque of the limb will influence accuracy of the reflex torque
measur- ement and it is an adverse influence for quantitative
of muscle spasticity. Therefore the goal of this research are
to build a mathematical model of the spasticity of muscle and
to identify the parameters . By using the model one can
explore the mechan- ism of spasticity from subject
experiments. Three models were developed in this research, one
is a linear model the others are nonlinear models. The major
difference between the two nonlinear models is the modeling of
gravitational torque. In current experiments the subjects were
tested under supine position and the effect of gravitational
torque must be considered. The other nonlinear element is to
model dynamics of the stretched flexors of the elbow. From the
physiologic anatomy one may find that the spasm of muscles for
the strokes is due to stretch reflex of affected muscle. The
reflex loop can be modeled as two parts, one is velocity
dependent and the other is position dependent. From the model
developed in this thesis, one can decompose the reflex torque
into two parts and it may be helpful in understanding the
mechanism of mucle spasticity. The results indicate that by
using the models respectively, one can identify, the velocity
independent reflex torque, the position-dependent torque, the
gravitation torque and the inert- ial torque. The coefficient
of torsion stiffness can position dependent torque used to
quantify the spasticity of muscle. It will be clinically
helpful on the diagnosis, assessment and re- habilitation of
stroke patients.
