|Stretching as an intervention to treat deficits in flexibility is a largely supported, used, and understood practice in physical therapy. The Center for Disease Control and Prevention estimated that one in every 303 live births resulted in cerebral palsy (CP) and that CP is the most common cause of motor disability in children. Cerebral palsy is a non-progressive lesion of the central nervous system that results from brain injury during the first two years of life. As a result of the brain injury, certain muscles may be receiving incorrect stimulus from the brain leading to increased tone, tightening/shortening of the muscles, decreased strength of the muscle, and lack of ability to control the muscle when moving.
A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
