the quality of life for a patient the quality of life for a patient suffering from movement disorders. suffering from movement disorders.
The system/device must provide The system/device must provide evidence that the quality of life has evidence that the quality of life has improved post surgery so that improved post surgery so that insurance companies will continue to insurance companies will continue to fund deep-brain stimulus fund deep-brain stimulus rehabilitation.rehabilitation.
Definition of Quality of LifeDefinition of Quality of Life Quality of life is a measure of the means Quality of life is a measure of the means
that people live within their own that people live within their own environments in ways that are best for environments in ways that are best for themthem
The ultimate goal of deep brain stimulation The ultimate goal of deep brain stimulation surgery is to enable people to live quality surgery is to enable people to live quality lives -- lives that are both meaningful and lives -- lives that are both meaningful and enjoyed, but are also functional mentally, enjoyed, but are also functional mentally, physically and socially.physically and socially.
