This book is an informative guide for both the patient and therapist, and  provides a series of exercises that target the most important muscles  for those with spastic paresis. Actively practicing the exercises  prescribed in this self-rehabilitation manual will allow the patient to  see continued improvement in their muscle functioning. Spastic paresis is the consequence of a central nervous system disorder such as a stroke, traumatic brain or spinal cord injury, multiple sclerosis, or a tumor of the nervous system, conditions that may have occurred in childhood or adulthood. In spastic paresis two problems coexist: the word  paresis  means that when the brain sends a command to a muscle to contract, this order is incompletely received by the muscle; the word  spastic  indicates that at the same time muscles cannot relax normally and have a tendency to be spontaneously overactive.
