To develop a reliable and objective technique for quantifying spastic hypertonia, ten
chronically hemiplegic patients with varying degrees of spasticity were studied on three …

Spastic hypertonia has been defined as a motor disorder characterized by a velocity-
dependent increase in tonic stretch reflexes (muscle tone) with exaggerated tendon jerks …

A delayed consequence of a lesion affecting the upper motor neuron pathways is the
appearance of some forms of motor overactivity, including spasticity. Many of these are …

Spacticity is a hallmark of upper motor neuron lesion, which is easily identified but is difficult
to quantify and treat. The Ashworth scale lacks reliability. Available biomechanical and …

Background and Purpose. Studies in subjects with spastic hypertonia indicate that the
higher resistance to stretch in the spastic muscles is not only due to hyperactive stretch …

Introduction Spasticity may be defined as a velocity-sensitive increase in the resistance of
muscles to passive stretch associated with exaggerated tendon jerks resulting from upper …

Static and dynamic stiffnesses of voluntarily activated elbow muscles were compared in
spastic and contralateral arms of 15 subjects with spastic hemiparesis. Stiffnesses were …

Spasticity is considered an important neural contributor to muscle hypertonia in children with
cerebral palsy (CP). It is most often treated with antispasticity medication, such as Botulinum …

The measurement of spasticity has always presented a problem to clinicians and
researchers alike. As yet, there is no literature addressing the reproducibility of the existing …
