Abstract
Mechanical properties of relaxed lower leg muscles were assessed by torque measurements during imposed constant velocity dorsiflexion-plantarflexion cycles. At low angular velocities, they exhibited an elastic and an energy-consuming, velocity-independent (plastic) resistance. In most patients with long-standing spasticity, both of these were enhanced. The results support the hypothesis of secondary structural changes of muscles in spasticity.
摘要
通过在施加的恒速背屈 - 跖屈循环过程中测量扭矩来评估放松状态下小腿肌肉的力学性能。在低角速度下，它们表现出弹性和耗能的、与速度无关的（塑性）阻力。在大多数患有长期痉挛的患者中，这两种阻力都增强了。这些结果支持了痉挛状态下肌肉继发性结构变化的假说。
