摘要

背景：在多发性硬化症（pwMS）患者内收肌痉挛的治疗中，了解肌肉的力学特性是如何改变的是很重要的。方法对42例双侧pwMS进行评价。采用改良Ashworth量表（MAS）测定髋内收肌痉挛程度，将pwMS分为MAS0、MAS1、MAS1+、MAS2四组。使用MyotonPro®（Myoton AS，爱沙尼亚）从(i)腹部、（ii）肌腱肌和（iii）肌腱部位测定肌肉的机械性能（张力、刚度、弹性）。从腹部和肌腱肌部位获得的测量结果进行了比较，关于MAS，肌肉的音调和僵硬度有差异(p <；0.05)。腹部和腱肌部位的弹性值无差异(p >；0.05)。MAS0和MAS2肌腱肌部位的张力和僵硬度不同(p <；0.05)。所有的肌张力计值在MAS的肌腱部位都有差异(p <；0.05)。弹性与MAS之间的关系仅存在于肌腱区域，两者之间呈中度负相关(r = 0.358, p <；0.05)。随着痉挛性的发展，粘弹性性质的变化从收缩结构向非收缩结构推进。在肌腱区域的机械影响不仅局限于张力和刚度，它也影响弹性。在选择治疗痉挛的技术时，应根据痉挛的严重程度考虑肌肉的区域特征。

Characterization of the mechanical changes of adductor muscles in the lower extremities for patients with multiple sclerosis

Background

It is important to know how the mechanical properties of the muscles change in the management of adductor spasticity in patients with Multiple Sclerosis (pwMS).

Methods

This study was conducted by evaluating forty-two pwMS bilaterally. The Modified Ashworth Scale (MAS) was used to determine the hip adductor spasticity level, and pwMS were divided into four groups (MAS0, MAS1, MAS1+, MAS2) regarding the MAS grade. MyotonPro® (Myoton AS, Estonia) was used to determine mechanical properties (tone, stiffness, elasticity) of the muscle from the (i) belly, (ii) musculotendinous, and (iii) tendon sites of the muscle.

Findings

The measurements obtained from the belly and musculotendinosus sites of the muscle were compared concerning the MAS, there was a difference in the tones and stiffness of the muscle (p < 0.05). There was no difference in elasticity values of belly and musculotendinosus sites (p > 0.05). Musculotendinosus sites' tone and stiffness were different between MAS0 and MAS2 (p < 0.05). All of the myotonometer values were differences in tendon sites regarding the MAS (p < 0.05). The relationship between elasticity and the MAS was only present in the tendon region, and a moderate negative correlation was observed between them (r = 0.358, p < 0.05).

Interpretation

As spasticity progresses, the change in viscoelastic properties advances from contractile structures to non-contractile structures. Mechanical influence in the tendon area is not only confined to tone and stiffness, it also affects elasticity. In the techniques chosen for the management of spasticity, the regional characteristics of the muscle should be taken into consideration according to the severity of spasticity.

期刊介绍： Clinical Biomechanics is an international multidisciplinary journal of biomechanics with a focus on medical and clinical applications of new knowledge in the field. The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and technologies. Clinical Biomechanics aims to strengthen the links between laboratory and clinic by publishing cutting-edge biomechanics research which helps to explain the causes of injury and disease, and which provides evidence contributing to improved clinical management. A rigorous peer review system is employed and every attempt is made to process and publish top-quality papers promptly. Clinical Biomechanics explores all facets of body system, organ, tissue and cell biomechanics, with an emphasis on medical and clinical applications of the basic science aspects. The role of basic science is therefore recognized in a medical or clinical context. The readership of the journal closely reflects its multi-disciplinary contents, being a balance of scientists, engineers and clinicians. The contents are in the form of research papers, brief reports, review papers and correspondence, whilst special interest issues and supplements are published from time to time. Disciplines covered include biomechanics and mechanobiology at all scales, bioengineering and use of tissue engineering and biomaterials for clinical applications, biophysics, as well as biomechanical aspects of medical robotics, ergonomics, physical and occupational therapeutics and rehabilitation.
