概括

初级侧面硬化症 (PLS) 诊断可能并不总是在2-deoxy-2-[18F]-D-葡萄糖正子发射断层扫描 (FDG-PET) 上显示初级运动皮层低代谢. 这项研究强调了PLS异质性,表明需要更精确的诊断工具.

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...
