Physical inactivity has been recognised as one of the common modifiable risk factors for non-communicable diseases such as heart disease, stroke, cancer, chronic respiratory diseases and diabetes. Increased level of physical activity is very effective for health maintenance. In this book, experts from all over the world present evidence for therapeutic physical activities illustrated by different cases. Physical activity can serve as both a preventive measure and a rehabilitation tool. The contents of this book cover the benefits of physical activity from young children with cerebral palsy to older adults with Parkinson's disease. Some chapters focus on specific illness, such as asthma; others study more popular problems like lower back pain. Furthermore, fall risks increase with age. It is a growing problem among the elders, their family, the community, the governments, and the world at large. There is a chapter in this book discussing this issue specifically. Individuals with one of the impairments touched upon in this book, as well as their families, doctors and other health workers can benefit from its contents. The topics of this book include kidney disease, coronary or peripheral artery disease, asthma, vestibular impairments, obstructive sleep apnea, cancer, lower back pain, Alzheimer's disease, dementia, Parkinson's disease, risk of falls, autism spectrum disorder, and cerebral palsy. Students and researchers can use this book as reference when they investigate the effects of physical activity as a preventive measure or therapeutic modality for other populations.
