Chronic transformation of muscle in spasticity: a peripheral contribution to increased tone

Chronic transformation of muscle in spasticity: a peripheral contribution to increased tone

A Hufschmidt et al. J Neurol Neurosurg Psychiatry. 1985 Jul.

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.
