The ability to walk safely, easily, and in an aesthetically pleasing manner is a skill learned early and highly prized. Although it is typically taken for granted, gait is key to mobility and functional independence and at the core of our ability to carry out many activities of daily living. In older adults and patients with neurological deficits, ease and safety in walking may become compromised, and gait is often viewed as abnormal, ., as a disorder. While not an inevitable part of aging, gait disorders are common among older adults and in patients with neurological disease. By some estimates, as much as 20% of non-institutionalized older adults.
