概括

这项研究量化了多发性硬化症患者的脚抵抗和肌肉活动,发现性是双边的,取决于速度. 结合异动力学和EMG测量,可以检测出微妙的变化,以便早期管理.

科学领域:

神经科学是一个神经科学.
生物力学生物力学
康复科学康复科学康复科学

背景情况:

多发性硬化症 (MS) 通常会导致四肢硬和,影响运动功能.
量化对被动运动 (RPM) 和肌肉活动的抵抗对于理解MS (PwMS) 患者的性至关重要.

研究的目的:

在PwMS中使用表面电肌图 (sEMG) 来量化脚足部屈曲器对被动运动 (RPM) 和肌肉活动的抵抗.
为了区分PwMS与性的被动和反射度组件.

主要方法:

通过使用异动力动力计,以5°/s至210°/s的速度进行了被动脚背部曲.
表面电肌图 (sEMG) 与扭矩测量同时记录了脚部 flexor 肌肉活动.
脚根据RPM在5°/s的速度被归类为具有较高或较低的抗性.

主要成果:

在较高的速度 (180°/s和210°/s) 时,在较弱和较强的脚中,RPM显著增加.
sEMG活动在两只四肢的速度之间显著增加,并且以相似的方式增加.
脚阻力 (APT) 通过侧面和速度进行预测,而sEMG则仅通过速度进行预测.

结论:

在PwMS中,度表现出双边特征,具有不同的被动和反射度.
综合的异动力学和sEMG分析可以识别PwMS的微妙,亚临床变化.
早期发现这些变化可以指导量身定制的管理策略,以改善结果.

Alterations in Muscle Tone ll

Alterations in Muscle Tone ll

Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...

Alterations in Muscle Tone lll

Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...
