The present study focuses on the ability of participants with spastic hemiparesis caused by cerebral palsy to adjust an ongoing movement. Typical symptoms associated with the disorder would lead one to expect that people with spastic hemiparesis would be unable to adjust their movements quickly and proportionally to a sudden change in the environment with their spastic arm. The results of the p...

[Purpose] To examine the distribution of and relationship between the Gross Motor Function, Manual Ability, and Communication Function Classification Systems in different limbs of children with spastic cerebral palsy. We also investigated whether the four predicting variables of gender, age, manual ability, and gross motor classifications could significantly predict effective and non-effective ...

The upper motor neuron (UMN) syndrome is a collection of interactive positive signs (associated with spastic hypertonia) and negative signs, such as muscle weakness and loss of voluntary control. In clinical practice, the distinction between active and passive functions allows identifying appropriate treatment objectives. During the last decades, many studies have evaluated the possibility to t...

The effect of a specific EMG biofeedback treatment protocol on quantified changes in neuromuscular measures and functional activities was examined among the upper extremities of 22 chronic stroke patients who each received 60 feedback training sessions. These data were compared with changes measured from a Control Group of 9 (no treatment) patients. Those patients receiving feedback training sh...

Appropriate interlimb coordination of the lower extremities is particularly important for a variety of functional human motor behaviors such as jumping, kicking a ball, or simply walking. Specific interlimb coordination patterns may be especially impaired after a lesion to the motor system such as stroke, yet this has not been thoroughly examined to date. The purpose of this study was to invest...

objective spastic cerebral palsy (cp) is one of the most difficult and disabling conditions that requires medical attention and treatment. the aim of this study was to assess the efficacy and safety of oral tizanidine in treating spasticity in children with spastic cp. materials & methods sixty children with spastic cerebral palsy were enrolled in a double-blind, placebo-controlled, randomized ...

A 4-year-old girl presented with increasing falls and progressive limb stiffness noticed for 2 months. There was no history of cognitive decline, seizures, or vision impairment. Examination revealed spastic quadriparesis, with no sensory or cerebellar abnormalities. A suggestive MRI scan of the brain (figure) and reduced galactocerebrosidase activity in leukocytes confirmed the diagnosis of lat...

This study characterizes tonic and phasic stretch reflex and stiffness and viscosity changes associated with spastic hemiparesis. Perturbations were applied to the ankle of 27 hemiparetic and 36 healthy subjects under relaxed or active contracting conditions. A nonlinear delay differential equation model characterized phasic and tonic stretch reflex gains, elastic stiffness, and viscous damping...

AIM In children with bilateral spastic cerebral palsy (CP), periventricular leukomalacia (PVL) is commonly identified on magnetic resonance imaging. We characterized this white matter condition by examining callosal microstructure, interhemispheric inhibitory competence (IIC), and mirror movements. METHOD We examined seven children (age range 11y 9mo-17y 9mo, median age 15y 10mo, four females...

Mechanism of coronary spasm was examined regarding endothelium-related relaxation and contraction produced by smooth muscle cells of spastic vessels isolated from Göttingen miniature pigs. In these pigs, coronary artery spasm was documented angiographically in vivo three months after endothelial denudation, and spastic and control segments of the coronary artery were suspended in organ chambers...
