Specialists in neurology and rehabilitation present the first book dedicated solely to the diagnosis and treatment of what is most often called spasticity, but sometimes upper motor neuron syndrome or muscle overactivity. They define the process for the diagnosis, the basic science behind its pathophysiology, the measurement tools used for evaluation, and the available treatment options. Among the topics are the epidemiology of spasticity in the adult and child, assessing spasticity in the upper extremity, botullinum toxin in the treatment of lower limb spasticity, surgery, genetic causes, spasticity due to multiple sclerosis, spasticity due to traumatic brain injury, and animal models.
