title: Testing and modelling of spasticity.
abstract: The aim of this investigation was to develop a clinically applicable method for quantitative evaluation of spasticity about the knee and to determine the minimum instrumentation necessary for a quick and simple estimation of spasticity. Skeletal muscle spasticity is assessed by physical therapists as increased resistance of a particular muscle group to manually induced passive movement. In this study the passive movement was produced by the force of gravity while the resistance was observed from the joint goniogram. Spasticity of the knee extensors was measured on patients with spinal cord injuries. Records of severe, moderate, and slight spasticity are presented in the paper. A mathematical model has been developed describing the behaviour of healthy and spastic extremity.
