Spasticity after stroke: physiology, assessment and treatment

A Thibaut, C Chatelle, E Ziegler, MA Bruno… - Brain injury, 2013 - Taylor & Francis
Background: Spasticity following a stroke occurs in about 30% of patients. The mechanisms
underlying this disorder, however, are not well understood. Method: This review aims to …

Pathophysiology of spasticity in stroke

D Burke, J Wissel, GA Donnan - Neurology, 2013 - AAN Enterprises
Spasticity is defined clinically by increased muscle tone and tendon jerk hyperreflexia in
patients who are at rest. However, the excitability of spinal circuits changes during …

The physiological basis of neurorehabilitation-locomotor training after spinal cord injury

M Hubli, V Dietz - Journal of neuroengineering and rehabilitation, 2013 - Springer
Advances in our understanding of the physiological basis of locomotion enable us to
optimize the neurorehabilitation of patients with lesions to the central nervous system, such …

Operant conditioning of a spinal reflex can improve locomotion after spinal cord injury in humans

AK Thompson, FR Pomerantz… - Journal of …, 2013 - Soc Neuroscience
Operant conditioning protocols can modify the activity of specific spinal cord pathways and
can thereby affect behaviors that use these pathways. To explore the therapeutic application …

Passive muscle properties are altered in children with cerebral palsy before the age of 3 years and are difficult to distinguish clinically from spasticity

M Willerslev‐Olsen, J Lorentzen… - … medicine & Child …, 2013 - Wiley Online Library
Aim Clinical determination of spasticity is confounded by the difficulty in distinguishing reflex
from passive contributions to muscle stiffness. There is, therefore, a risk that children with …

Background Spastic paresis in cerebral palsy (CP) is characterized by increased joint
stiffness that may be of neural origin, ie improper muscle activation caused by eg …

The effect of post-stroke lower-limb spasticity on the control of standing balance: inter-limb spatial and temporal synchronisation of centres of pressure

JC Singer, A Mansfield, CJ Danells, WE McIlroy… - Clinical …, 2013 - Elsevier
Background Challenges in stability control are common post-stroke. Although lower-limb
spasticity is a common sensorimotor consequence post-stroke, its potential to further …
