Muscle activation during, repetitive movements in normal and spastic man
Muscle activation during, repetitive movements in normal and spastic man
The relationship between voluntary movement and passive stretch responses was investigated. Thirty-three normal subjects, 26 patients with spasticity of various causes, twelve with Parkinsonism and eight with dystonia volunteered as subjects for this study. The integrated error score at 1 and 2 minutes and surface electromyograms were recorded during a predictable sinusoidal tracking task. The patterns of the profiles of EMG activity in patients with different types of increased muscle tone were established for the conditions of the task. This method was then used to evaluate two different types of treatment. The results showed that stretch responses were not a major factor in the impairment of voluntary movement in any of the groups of subjects. In spasticity, evidence was presented which suggests that patients had lost the ability to activate their triceps muscles selectively.

Abstract
The relationship between voluntary movement and passive stretch responses was investigated. Thirty-three normal subjects, 26 patients with spasticity of various causes, twelve with Parkinsonism and eight with dystonia volunteered as subjects for this study. The integrated error score at 1 and 2 minutes and surface electromyograms were recorded during a predictable sinusoidal tracking task. The patterns of the profiles of EMG activity in patients with different types of increased muscle tone were established for the conditions of the task. This method was then used to evaluate two different types of treatment. The results showed that stretch responses were not a major factor in the impairment of voluntary movement in any of the groups of subjects. In spasticity, evidence was presented which suggests that patients had lost the ability to activate their triceps muscles selectively.
