Objectives To determine the reliability and validity of Modified Heckmatt scale in assessing muscle echotexture spasticity. Design Prospective, observational, 2-center study. Two residents 2 ultrasound experienced staff physicians each rated 100 images that were also analyzed using quantitative gray-scale. Setting Academic ambulatory spasticity clinic. Participants (N=50) included 45 patients w...

BACKGROUND AND PURPOSE There is currently no consensus on (1) the percentage of patients who develop spasticity after ischemic stroke, (2) the relation between spasticity and initial clinical findings after acute stroke, and (3) the impact of spasticity on activities of daily living and health-related quality of life. METHODS In a prospective cohort study, 301 consecutive patients with clinic...

BACKGROUND Muscle spasticity is a disability caused by damage to the pyramidal system. Standard treatments for spasticity include muscle stretching, antispastic medications, and tendon release surgeries, but treatment outcomes remain unsatisfactory. Anodal transcranial direct current stimulation (tDCS) in patients with muscle spasticity is known to result in significant improvement in spastic t...

OBJECTIVE The adverse events (AEs) with botulinum toxin type-A (BoNTA), used for indications other than spasticity, are widely reported in the literature. However, the site, dose, and frequency of injections are different for spasticity when compared to the treatment for other conditions and hence the AEs may be different as well. The objective of this study was to summarize the AEs reported in...

BACKGROUND AND OBJECTIVE The increase in resistance to passive muscle stretch in a paretic limb due to an upper motor neurone lesion is often referred to as muscle spasticity. However, this terminology is inaccurate and does not take into account the complex pathogenesis of the condition or describe the factors that contribute to the clinically observed changes in muscle tone. In this report we...

Spasticity has been defined as a motor disorder characterized by a velocity-dependent increase in tonic stretch reflex (muscle tone). Muscle tone consists of mechanical-elastic characteristics, reflex muscle contraction and other elements. The aims of this study were to determine whether to assess spasticity quantitatively, and to characterize biomechanical and electromyographic spasticity asse...

Introduction Intervention to lengthen the musculotendinous unit, or to reduce its activity, are commonly performed in children with cerebral palsy (CP) with joint passive range being used as a surrogate outcome measure of musculotendinous unit length. The development of muscle deformity in children with CP is often attributed to spasticity, which has been defined variably as a velocity-dependen...

BACKGROUND The development of spasticity with age in children with cerebral palsy (CP) has, to our knowledge, not been studied before. In 1994, a register and a health care program for children with CP in southern Sweden were initiated. In the programme the child's muscle tone according to the modified Ashworth scale is measured twice a year until six years of age, then once a year. We have use...

Background. Arm spasticity is a challenge in the care of chronic stroke survivors with motor deficits. In order to advance spasticity treatments, a better understanding of the mechanism of spasticity-related neuroplasticity is needed. Objective. To investigate brain function correlates of spasticity in chronic stroke and to identify specific regional functional brain changes related to rehabili...
