The diverse exercise goals of the aging population present several challenges to physicians. Whereas some Masters athletes aim to set personal time records, sedentary elderly persons may look to exercise to help maintain independence and combat functional decline. This review article examines the common cardiovascular and neuromuscular physiological changes associated with aging and how regular exercise is used to improve physiological parameters and functional abilities. Exercise precautions specific to the elderly population are discussed. Exercise recommendations for persons with osteoarthritis and after joint arthroplasty also are presented.
Context:Chronic traumatic encephalopathy (CTE) is a rare progressive neurologic disorder that can manifest as a combination of cognitive, mood and behavioral, and neurologic symptoms. Despite clinically apparent symptoms, there is no imaging or other diagnostic test that can confirm diagnosis in living subjects. Diagnosis can only be confirmed postmortem by specific histopathologic features within the brain tissue identified on autopsy. CTE represents a unique tauopathy that is distinct from other neurodegenerative diseases.Evidence Acquisition:PubMed was searched from 1990 to 2013 for sport concussion and chronic traumatic encephalopathy. Articles were also identified from bibliographies of recent reviews and consensus statements.Study Design:Clinical review.Level of Evidence:Level 5.Results:Although CTE is postulated to occur as a result of repetitive mild traumatic brain injury, the specific etiology and risk factors have not yet been elucidated, and postmortem diagnosis makes causality difficult to determine.Conclusion:When counseling athletes and families about the potential association of recurrent concussions and the development of CTE, discussion of proper management of concussion is cornerstone. Unfortunately, to date, there is no equipment that can prevent concussions; however, rule changes and legislation may decrease the risk. It is imperative that return to play is medically supervised by a provider trained in the management of concussion and begins only once symptoms have resolved. In addition, athletes with permanent symptoms should be retired from contact sport.
Participation in contact sports exposes the athlete to a risk of cervical spine injury. Temporary neurological injuries manifesting as radiating arm pain or paresthesias, such as transient quadriparesis and stingers, present unique challenges for the sports medicine physician and will be reviewed in detail. The initial management of these conditions must recognize signs and symptoms of spinal cord injury and prevent further neurological sequelae. Evaluation will often include advanced imaging of the cervical spine in addition to serial neurological examinations. This review concludes with rational return-to-play guidelines for contact sport athletes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
