The loss of passive joint range of motion (i.e. contracture) is common in stroke and other neurological conditions. More than half of people with stroke or spinal cord injury will develop at least one contracture (Diong et al., 2012; Kwah et al., 2012). Contracture impairs physical function and can cause […]
In stroke-induced hemiparesis, muscles such as the plantar flexors undergo dramatic alterations that involve both physical shortening (decrease in fascicle length) and viscoelastic loss of extensibility (Kwah et al., 2012). This muscle disorder has been termed spastic myopathy (Gracies, 2015) and is commonly treated with stretching techniques. However, the effectiveness […]
Over the past 4.5 years, researchers from all over the world have written non-technical summaries on their research for the Motor Impairment Blog. Consequently, the Blog contains a rich archive of information on topics such as muscle strength and weakness, falls and balance, sensation, pain, motor control, and research methods. […]
Little is known about the small intrinsic foot muscles and their function during walking and running. In this video, Prof Andrew Creswell of the University of Queensland talks about the results of his research in which he has utilized imaging ultrasound and intramuscular electromyography to study the role of intrinsic […]
In young people with cerebral palsy, strength training increases the forces that their muscles produce. But does that mean that strength training helps young people with cerebral palsy walk better? Professor Nicholas Taylor talks about strength training and mobility in young people with cerebral palsy.
People who have had a stroke may develop disabling spasticity and contracture. In the upper limb, spasticity and contracture sometime manifest as a characteristic postural deformity: in standing, the relaxed arm is held with the shoulder adducted and internally rotated, the elbow flexed and pronated, and the wrist and fingers […]
