Évaluation de la mesure de la spasticité par le pendulum test Evaluation of pendulum testing of spasticity
2002
Objectives: To identify valid measurements of spasticity derived from the pendulum testof the leg in a representative population of spastic patients. Material and methods: Pendulum testing was performed in 15 spastic and 10 matched healthy subjects. The reflex-mediated torque evoked in quadriceps femoris, as well as muscle mechanical parameters (viscosity and elasticity), were calculated using mathematical modelling. Correlation with the two main measures derived from the pendulum test reported in the literature (the Relaxation Index and the area under the curve) was calculated in order to select the most valid. Results, discussion: Among mechanical parameters, only viscosity was found to be significantly higher in the spastic group. As expected, the computed integral of the reflex-mediated torque was found to be larger in spastics than in healthy subjects. A significant non-linear
